You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] which company started earlier, Black Diamond Equipment or la sportiva?

[Assistant] Let's start by looking at some similar examples.

[Tool] No examples found

[Assistant] Since we couldn't find any similar examples, let's proceed by searching for the entities "Black Diamond Equipment" and "La Sportiva" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Black Diamond Equipment (wd:Q2905359): Manufacturer of equipment for climbing, skiing, and mountain sports
2. anthracite, also known as black diamond, stone coal, Kilkenny coal, hard coal, crow coal (wd:Q182458): hard coal with a volatile component (gas) of less than 10 %
3. Black Diamond, also known as Black Diamond, Washington, Black Diamond, WA (wd:Q1191152): city in King County, Washington, United States
4. Black Diamond, also known as Black Diamond, FL, Black Diamond, Florida (wd:Q570406): census designated place in Citrus County, Florida, United States
5. carbonado, also known as black diamond (wd:Q429950): toughest form of natural diamond; it is an impure form of polycr...ne diamond consisting of diamond, graphite, and amorphous carbon
6. Black Diamond (wd:Q880216): former town in Alberta, Canada

9. Black Diamond (wd:Q784842): 2008 sophomore studio album by Buraka Som Sistema
10. Black Diamond (wd:Q3398877): Kiss song

[Assistant] The first result, "Black Diamond Equipment" (wd:Q2905359), seems to be the correct entity. Now, let's search for "La Sportiva".

[Tool]
Top 10 entity alternatives:
1. La Sportiva (wd:Q3821214): Outdoor Sporting Goods Company
2. Sociedad Sportiva Argentina, also known as La Sportiva (wd:Q39081671): defunct sports club in Buenos Aires
3. La Domenica Sportiva (wd:Q3208328): Italian TV series or program
4. SS Lazio, also known as S.S. Lazio, SSLazio, S.S.Lazio, SSL, S.S.L. (wd:Q2609): football section of the sports club based in Rome, Lazio, Italy

10. Associazione Sportiva La Fratellanza 1874 (wd:Q100527922)

[Assistant]
The first result, "La Sportiva" (wd:Q3821214), seems to be the correct entity. Now, let's look for the founding dates of these companies. We can use the property "founded" (P571) to find this information.

Let's check the triples for both entities to see if they have a "founded" date.

First, for Black Diamond Equipment:

[Tool]
Got 1 row and 3 columns:
| subject                               | property             | object                              |
| ------------------------------------- | -------------------- | ----------------------------------- |
| Black Diamond Equipment (wd:Q2905359) | inception (wdt:P571) | 1989-12-01T00:00:00Z (xsd:dateTime) |

[Assistant] The founding date of Black Diamond Equipment is December 1, 1989. Now, let's check the founding date for La Sportiva.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[Assistant] The property "temporal range end" (wd:P524) looks promising as it could indicate when the dinosaurs went extinct. Let's check the value of this property for the entity "dinosaur" (wd:Q430).

[Tool] Got no rows and 1 columns

[Assistant] It appears that the "temporal range end" property does not have a direct value for the "dinosaur" entity. Let's try to find out if there is a specific event or period associated with the extinction of dinosaurs. We can look for significant events (wd:P793) related to the "dinosaur" entity.

[Tool] Got no rows and 1 columns

[Assistant] It seems that there are no significant events directly linked to the "dinosaur" entity. However, we can try to find the extinction event that is commonly associated with the end of the dinosaurs. Let's search for the entity "Cretaceous–Paleogene extinction event" and see if it is linked to dinosaurs.

[Assistant]
From the list of properties and values associated with the "Cretaceous-Paleogene mass extinction" event (wd:Q55811), we can see that:

- The event is an instance of an "extinction event" (wd:Q55814).
- The point in time of the event is approximately 66 million years ago.
- The immediate cause of the event is the "Chicxulub impactor" (wd:Q5096573).

Let's construct a SPARQL query to retrieve these details and provide a clear answer to the user's question.

[Tool]
Got 1 row and 2 columns:
| timePeriod                              | cause                            |
| --------------------------------------- | -------------------------------- |
| -66000000-01-01T00:00:00 (xsd:dateTime) | Chicxulub impactor (wd:Q5096573) |

[Assistant]
Based on the results, the "Cretaceous-Paleogene mass extinction" event, which is widely recognized as the cause of the extinction of dinosaurs, occurred approximately 66 million years ago and was caused by the "Chicxulub impactor."

Here is the final SPARQL query and answer:

```sparql

[Assistant]
We have found the correct entity for Pink Floyd, which is `wd:Q2306`. Now, let's find the properties that might indicate the formation date of these bands. We will search for properties related to "formation" or "founded" for both entities.

First, let's search for properties related to "formation" or "founded" for Queen.

[Tool]
Top 10 property alternatives:
1. inception, also known as initial release date, founded in, founded on, founded on date, founding date (wd:P571 as p/wdt): time when an entity begins to exist; for date of official opening use P1619, start time
2. location of formation, also known as place of incorporation, originates from, place of establishment, place of formation, place of foundation (wd:P740 as p/wdt): location where a group or organization was formed, location of creation
3. work period (start), also known as start working, flourished (start), start time for work, start date of activity, fl. (start) (wd:P2031 as p/wdt): start of period during which a person or group flourished (fl. = "floruit") in their professional activity, start time, floruit

No other items found

[Assistant] The property `inception` (P571) seems to be the most relevant for the formation date of Queen. Let's now search for the same property for Pink Floyd.

[Tool]
Top 10 property alternatives:
1. inception, also known as initial release date, founded in, founded on, founded on date, founding date (wd:P571 as p/wdt): time when an entity begins to exist; for date of official opening use P1619, start time
2. has part(s), also known as has component, incorporates, has ingredient, has ingredients, has member (wd:P527 as p/wdt): part of this subject; inverse property of "part of" (P361). See also "has parts of the class" (P2670).
3. location of formation, also known as place of incorporation, originates from, place of establishment, place of formation, place of foundation (wd:P740 as p/wdt): location where a group or organization was formed, location of creation
4. work period (start), also known as start working, flourished (start), start time for work, start date of activity, fl. (start) (wd:P2031 as p/wdt): start of period during which a person or group flourished (fl. = "floruit") in their professional activity, start time, floruit

6. country of origin, also known as origin country, place of origin, originates from, country, CoO (wd:P495 as p/wdt): country of origin of this item (creative work, food, phrase, product, etc.), significant place, country

No other items found

[Assistant]
The property `inception` (P571) is also the most relevant for the formation date of Pink Floyd. Now, let's construct a SPARQL query to compare the formation dates of Queen and Pink Floyd.

We will select the formation dates for both bands and then compare them to determine which band was formed earlier.

[Tool]
Got 1 row and 2 columns:
| queenFormationDate                  | pinkFloydFormationDate              |
| ----------------------------------- | ----------------------------------- |
| 1970-01-01T00:00:00Z (xsd:dateTime) | 1964-01-01T00:00:00Z (xsd:dateTime) |

[Assistant]
Based on the results, Pink Floyd was formed earlier than Queen. Pink Floyd was formed on January 1, 1964, while Queen was formed on January 1, 1970.

Now, let's finalize the answer with an ASK query to confirm this result.

We will use an ASK query to check if the formation date of Pink Floyd is earlier than the formation date of Queen.

[Tool] True

[Assistant]
The ASK query confirms that Pink Floyd was indeed formed earlier than Queen.

Therefore, the answer to the question "Which band is created earlier, Queen or Pink Floyd?" is:

**Pink Floyd**

Here is the final SPARQL query and answer:

```sparql
ASK WHERE {
  wd:Q2306 wdt:P571 ?pinkFloydFormationDate .
  wd:Q15862 wdt:P571 ?queenFormationDate .
  FILTER(?pinkFloydFormationDate < ?queenFormationDate)
}
```

Answer: **True**

So, Pink Floyd was formed earlier than Queen.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] What is the coordinate location of Shenzhen ?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
In which city is the headquarter of Air China?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q51747 wdt:P159 ?uri
}

Using entities:
Air China, also known as CCA, Air China Limited, CA (wd:Q51747): flag carrier of the People's Republic of China

Using properties:
headquarters location, also known as headquarters locality, seat, headquarters town, HQ, HQ location (wd:P159 as wdt): city or town where an organization's headquarters is or has been situated. Use P276 qualifier for specific building, significant place

[Assistant] From the example, we can see that the property `headquarters location` (P159) is used to find the city where an organization's headquarters is located. However, for finding the coordinate location of a city, we need a different property. Let's search for the property that represents the coordinate location.

[Tool]
Top 10 property alternatives:
1. coordinate location, also known as point on a map, gps coordinates, gps location, latitude, location (wd:P625 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): geocoordinates of the subject. For Earth, please note that only WGS84 coordinating system is supported at the moment
2. this zoological name is coordinate with, also known as coordinate name (wd:P2743 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): links coordinate zoological names, different from
3. coordinates of depicted place, also known as depicted item geolocation, geolocation of object, object geolocation (wd:P9149 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): coordinates of the place depicted in the work (or Commons image)
4. location map (wd:P1943 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): blank geographic map image suitable for overlaying coordinate points, as defined at c:Category:Location maps, image
5. genomic start, also known as start coordinate, genomic from, Genloc From, from, Genloc Start (wd:P644 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): genomic starting coordinate of the biological sequence (e.g. a gene)
6. set in environment, also known as set in location, takes place in, setting location, playing in, narrative set in (wd:P8411 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): environment (geographic feature, building type, etc.) the narrative work is set in, significant place, depicts
7. narrative location, also known as set in location, set in, setting, setting location, setting of work (wd:P840 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): the narrative of the work is set in this location, significant place, depicts
8. location of discovery, also known as found in, location of discovered object, place of discovery, site of discovery, source (wd:P189 as pqn/pqv/psn/psv/prn/prv/p/pr/ps/pq/wdt/wdtn): where the item was located when discovered, significant place

Use qualifier "determination method" (P459) to indicate how, coordinate location

[Assistant] The top result is `coordinate location` (P625), which seems to be the correct property for finding the geocoordinates of a place. Now, let's find the entity for Shenzhen.

[Tool]
Top 10 entity alternatives:
1. Shenzhen, also known as Sham Chun (wd:Q15174): Sub-provincial division in China

10. Shenzhen Airlines, also known as Shenzhen Air (wd:Q974899): airline headquartered in Bao'an, Shenzhen, Guangdong, China and based in Shenzhen Bao'an International Airport

[Assistant]
The first result, `Shenzhen` (Q15174), is the entity representing the city of Shenzhen. Now, let's construct a SPARQL query to find the coordinate location of Shenzhen using the property `coordinate location` (P625).

Here is the initial SPARQL query:

```sparql
SELECT ?coordinate WHERE {
  wd:Q15174 wdt:P625 ?coordinate .
}
```

I will now execute this query to get the coordinate location of Shenzhen.

[Tool]
Got 1 row and 1 column:
| coordinate                                   |
| -------------------------------------------- |
| POINT(114.054000 22.535000) (geo:wktLiteral) |

[Assistant]
The coordinate location of Shenzhen is `POINT(114.054000 22.535000)`.

Here is the final SPARQL query and answer:

```sparql
SELECT ?coordinate WHERE {
  wd:Q15174 wdt:P625 ?coordinate .
}
```

Answer: The coordinate location of Shenzhen is `POINT(114.054000 22.535000)`.

Now, I will provide the final answer using the `answer` function.

[User] How many spouses do head of states have on average?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
How often did Jane Fonda marry?

SPARQL:
SELECT ( COUNT( DISTINCT ?uri ) as ?c ) WHERE {
  wd:Q41142 wdt:P26 ?uri .
}

Using entities:
Jane Fonda, also known as Jane Seymour Fonda, Jayne Seymour Fonda, Hanoi Jane (wd:Q41142): American actress and activist, television actor, autobiographer, film producer, voice actor, stage actor, film actor, writer, model, actor

Using properties:
spouse, also known as married partner, married to, marry, partner, spouses (wd:P26 as wdt): the subject has the object as their spouse (husband, wife, partn...etc.). Use "unmarried partner" (P451) for non-married companions, significant person, relative

Example 2:
Question:
How many emperors did China have?

SPARQL:
SELECT ( COUNT( DISTINCT ?uri ) as ?count ) WHERE {
  ?uri wdt:P39 wd:Q268218
}

Using entities:
Emperor of China, also known as Huang-ti, Huang Ti, Son of Heaven, thearch, Ti (wd:Q268218): sovereign of Imperial China

Using properties:
position held, also known as function, held position, holds position, job, office held (wd:P39 as wdt): subject currently or formerly holds the object position or public office

Example 3:
Question:
How many children did Benjamin Franklin have?

SPARQL:
SELECT ( COUNT( DISTINCT ?uri ) as ?c ) WHERE {
  wd:Q34969 wdt:P40 ?uri .
}

Using entities:

[Assistant] Based on these examples, we need to identify the entities and properties relevant to our question. We need to find the head of states and then count their spouses. Let's first search for the entity "head of state".

[Tool]
Top 10 entity alternatives:
1. head of state (wd:Q48352): official who holds the highest-ranked executive position in a sovereign state
2. Head of State (wd:Q1592282): 2003 American comedy film by Chris Rock
3. Head of State (wd:Q65225964): 2016 Armenian film
4. Başkan, also known as chairman, head of state, mayor, president (wd:Q60982271): Elected administrative position

10. office held by head of state, also known as head of state, position held by head of state, state headed by (wd:P1906): political office that is fulfilled by the head of state of this item

[Assistant]
From the search results, the most relevant entity for "head of state" is `wd:Q48352`. Now, let's find the property that indicates the number of spouses. We can use the property "spouse" (`wdt:P26`).

Next, we need to construct a query to find the average number of spouses for head of states. We will start by finding the head of states and then count their spouses.

Let's first list some head of states to ensure we have the correct entities and properties.

[Tool]
Got 38 rows and 3 columns, showing the first 10 rows below:
| subject                             | property                | object                    |
| ----------------------------------- | ----------------------- | ------------------------- |

[Assistant]
We have a list of head of states. Now, let's construct a query to count the number of spouses for each head of state and then calculate the average number of spouses.

Here is the initial query to count the number of spouses for each head of state:

```sparql
SELECT ?headOfState (COUNT(?spouse) AS ?spouseCount)
WHERE {
  ?headOfState wdt:P39 wd:Q48352 .
  ?headOfState wdt:P26 ?spouse .
}
GROUP BY ?headOfState
```

Let's execute this query to see the results.

[Tool]
Got 7 rows and 2 columns:
| headOfState                                        | spouseCount |
| -------------------------------------------------- | ----------- |
| Etazeta of Bithynia (wd:Q1289132)                  | 1 (xsd:int) |
| Jean-François Rewbell (wd:Q1685535)                | 1 (xsd:int) |
| Bảo Đại (wd:Q223771)                               | 4 (xsd:int) |
| Red Cloud (wd:Q312721)                             | 1 (xsd:int) |
| John, Margrave of Brandenburg-Küstrin (wd:Q648201) | 1 (xsd:int) |
| Vijaya (wd:Q888673)                                | 1 (xsd:int) |
| Llop I de Pallars (wd:Q9023677)                    | 1 (xsd:int) |

[Assistant]
We have the counts of spouses for each head of state. Now, let's calculate the average number of spouses. We can do this by summing up the `spouseCount` values and dividing by the number of head of states.

Here is the updated query to calculate the average number of spouses:

```sparql
SELECT (AVG(?spouseCount) AS ?averageSpouseCount)
WHERE {
  {
    SELECT ?headOfState (COUNT(?spouse) AS ?spouseCount)
    WHERE {
      ?headOfState wdt:P39 wd:Q48352 .
      ?headOfState wdt:P26 ?spouse .
    }
    GROUP BY ?headOfState
  }
}
```

Let's execute this query to get the average number of spouses.

[Tool]
Got 1 row and 1 column:
| averageSpouseCount    |
| --------------------- |
| 1.42857 (xsd:decimal) |

[Assistant]
The average number of spouses for head of states is approximately 1.43.

Here is the final SPARQL query and the answer:

```sparql
SELECT (AVG(?spouseCount) AS ?averageSpouseCount)
WHERE {
  {
    SELECT ?headOfState (COUNT(?spouse) AS ?spouseCount)
    WHERE {
      ?headOfState wdt:P39 wd:Q48352 .
      ?headOfState wdt:P26 ?spouse .
    }
    GROUP BY ?headOfState
  }
}
```

The average number of spouses for head of states is approximately 1.43.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] What is the Chinese zodiac animal that follows the ox?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
Which species does an elephant belong?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q7378 wdt:P279 ?uri .
}

Using entities:
elephant (wd:Q7378): large terrestrial mammals with trunks from Africa and Asia

Using properties:
subclass of, also known as rdfs:subClassOf, sort of, subcategory of, subgenre of, subtype of (wd:P279 as wdt): this item is a subclass (subset) of that item; ALL instances of ...stance of volcanic landform); Everest is an instance of mountain

[Assistant] None of the examples found seem directly relevant to our question about the Chinese zodiac. Let's try searching for the entity representing the Chinese zodiac.

[Tool]
Top 10 entity alternatives:
1. Chinese zodiac, also known as Celestial Branches, Earthly Branches (wd:Q1976204): lunar calendar classification, assigning a symbolic animal and i... year for a repeating cycle of twelve forming the Earthly Branch
2. Chinese Zodiac, also known as CZ12 (wd:Q391143): 2012 film directed by Jackie Chan

9. Dog (Chinese zodiac sign) (wd:L363339-S2)
10. rabbit (Chinese zodiac animal) (wd:L1116272-S2)

[Assistant] The first result, "Chinese zodiac" (wd:Q1976204), seems to be the most relevant. Now let's look for the property that links the animals in the zodiac to their order or sequence.

[Tool]

No other items found

[Assistant] It looks like we didn't find a specific property that indicates the order of the animals in the Chinese zodiac. However, we can try to find the animals themselves and then determine their order. Let's search for the ox in the Chinese zodiac.

[Tool]
Top 10 entity alternatives:
1. ox (Chinese zodiac animal) (wd:L1116270-S2)
2. Chinese zodiac, also known as Celestial Branches, Earthly Branches (wd:Q1976204): lunar calendar classification, assigning a symbolic animal and i... year for a repeating cycle of twelve forming the Earthly Branch
3. Ox, also known as Ox (zodiac) (wd:Q599644): 2nd sign of Chinese zodiac

No other items found

[Assistant]
The property "followed by" (wdt:P156) seems to be the most appropriate for finding the animal that comes after the ox in the Chinese zodiac. Let's construct a SPARQL query to find the animal that follows the ox.

Here is the SPARQL query:

```sparql
SELECT ?nextAnimal WHERE {
  wd:Q599644 wdt:P156 ?nextAnimal .
}
```

Let's execute this query to find the answer.

[Tool]
Got 1 row and 1 column:
| nextAnimal         |
| ------------------ |
| Tiger (wd:Q740762) |

[Assistant]
The Chinese zodiac animal that follows the ox is the tiger.

Here is the final SPARQL query and answer:

```sparql
SELECT ?nextAnimal WHERE {
  wd:Q599644 wdt:P156 ?nextAnimal .
