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.

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 happened to the dinosaurs ?

[Assistant]
The question "What happened to the dinosaurs?" is asking for an explanation or description of the fate or event that caused the extinction or significant change in the dinosaur population.

Step 1: Identify possible entities and properties:
- Entity: Dinosaurs
- Property: What happened to them? This could relate to extinction, cause of extinction, or events related to dinosaurs.

Step 2: Search for the entity "dinosaurs" in Wikidata to get its identifier.
I will search for "dinosaur" to find the relevant entity.

[Assistant]
The property "significant event" (wdt:P793) seems relevant as it can link the dinosaur entity to notable events, which might include their extinction.

Step 4: I will query for significant events related to dinosaurs (wd:Q430) to see if there is an event describing what happened to them.

[Tool] Got no rows and 2 columns

[Assistant]
There are no significant events directly linked to the dinosaur entity using the property "significant event" (wdt:P793).

Step 5: I will try another approach by looking for the "temporal range end" (wdt:P524) property for dinosaurs, which might indicate the time period when dinosaurs went extinct. Then I can look for events or explanations related to that time period.

[Tool] Got no rows and 1 columns

[Assistant]
There is no direct "temporal range end" property (wdt:P524) value for the dinosaur entity.

Step 6: I will search for the general concept of "extinction of dinosaurs" or "dinosaur extinction" as an event or topic in Wikidata to find relevant information. I will search for the entity "dinosaur extinction."

[Assistant]
There is an entity "extinction event" or "mass extinction" (wd:Q55814) which is a widespread and rapid decrease in the amount of life on earth.

There is also a specific "Cretaceous-Paleogene mass extinction" (wd:Q55811) which is the extinction event ending the Mesozoic Era, the era of dinosaurs.

Step 11: I will check if the dinosaur entity (wd:Q430) is linked to the "Cretaceous-Paleogene mass extinction" event (wd:Q55811) or if this event is described as the cause of dinosaur extinction. I will query for statements linking dinosaurs to this extinction event.

[Tool] Got no rows and 2 columns

[Assistant]
There are no direct properties linking the dinosaur entity (wd:Q430) to the "Cretaceous-Paleogene mass extinction" event (wd:Q55811).

Step 12: I will try to find a general description or statement about the "Cretaceous-Paleogene mass extinction" event (wd:Q55811) to see if it mentions dinosaurs or what happened to them. I will query for the description or statements related to this event.

[Tool]
Got 1 row and 1 column:
| ?description                             |
| ---------------------------------------- |
| extinction event ending the Mesozoic Era |

[Assistant]
The description of the "Cretaceous-Paleogene mass extinction" event (wd:Q55811) is "extinction event ending the Mesozoic Era." This implies it is the event that caused the extinction of dinosaurs, as dinosaurs lived during the Mesozoic Era.

Step 13: I will now construct a SPARQL query that returns the event "Cretaceous-Paleogene mass extinction" as the event that happened to the dinosaurs, along with its description. This will answer the question "What happened to the dinosaurs?" by pointing to the extinction event that ended their era.

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

[Assistant]
To answer the question "How many spouses do head of states have on average?" we need to follow these steps:

1. Identify the entity "head of state" in Wikidata.
2. Find the property that relates a person to their spouse(s).
3. Retrieve the number of spouses for each head of state.
4. Calculate the average number of spouses among all heads of state.

Let's start by searching for the entity "head of state" in Wikidata.

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]
The entity "head of state" is identified as wd:Q48352 in Wikidata, which refers to the official who holds the highest-ranked executive position in a sovereign state.

Next, we need to find the property that relates a person to their spouse(s). Let's search for properties related to "spouse" to identify the correct property.

[Tool]
Top 10 property alternatives:
1. spouse, also known as married partner, married to, marry, partner, spouses (wd:P26 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): the subject has the object as their spouse (husband, wife, partn...etc.). Use "unmarried partner" (P451) for non-married companions, significant person, relative
2. relative, also known as relatives, grandparent, relation, non-binary parent, niece (wd:P1038 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): family member (qualify with "kinship to subject", P1039; for direct family member please use specific property), significant person
3. unmarried partner, also known as romantic partner, partner of, partners, posslq, relationship (wd:P451 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): someone with whom the person is in a relationship without being married. Use "spouse" (P26) for married couples, significant person

10. relation (wd:P2309 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): qualifier to define a property constraint in combination with P2...h the property "relative" is "type of kinship" (P1039), not this

[Assistant]
The property "spouse" is identified as wd:P26 in Wikidata, which relates a subject to their spouse (husband, wife, partner, etc.).

Now, we need to find all individuals who are heads of state (wd:Q48352) and count how many spouses (wdt:P26) each has. Then we will calculate the average number of spouses among these heads of state.

I will write a SPARQL query to retrieve the count of spouses for each head of state and then calculate the average.

[Assistant] I found the Chinese zodiac animals as parts of the Chinese zodiac entity (wd:Q1976204). The animals include Rat (wd:Q721997), Rooster (wd:Q822621), Monkey (wd:Q740674), Rabbit (wd:Q844723), Ox (wd:Q599644), Dog (wd:Q755126), Goat (wd:Q867696), Horse (wd:Q869595), Dragon (wd:Q731434), Tiger (wd:Q740762), and others. However, the order is not clear from this list. I will now try to find the order of these animals in the Chinese zodiac cycle to identify which animal follows the Ox. I will search for the property or statement that indicates the order or position of these animals in the cycle.

[Assistant] The search for properties related to "season" did not return a direct property linking winter months to Germany. I will try searching for properties related to "month" to see if there is any property that links months to seasons or to Germany.

[Tool]
Top 10 property alternatives:
1. month of the year, also known as month of year, month (wd:P2922 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): month of the year during which this item occurs, applies to or is valid in, part of

[Assistant] The property "month of the year" (wdt:P2922) seems relevant as it indicates the month during which an item occurs or is valid. I will now try to find the months that are part of the winter season (wd:Q1311) using this property.

[Tool]
Got 6 rows and 3 columns:
| subject           | property                      | object             |

| winter (wd:Q1311) | month of the year (wdt:P2922) | December (wd:Q126) |
| winter (wd:Q1311) | month of the year (wdt:P2922) | July (wd:Q121)     |

[Assistant]
The months associated with the winter season (wd:Q1311) are January (wd:Q108), February (wd:Q109), December (wd:Q126), and unexpectedly also June (wd:Q120), July (wd:Q121), and August (wd:Q122). The latter three months are typically summer months in the northern hemisphere, so they might be related to winter in the southern hemisphere.

Since the question is about Germany, which is in the northern hemisphere, the relevant winter months should be December, January, and February.

I will now construct a SPARQL query to count the number of months that are part of the winter season in Germany.

[Assistant] The search for properties related to rivers for the Grand Canyon entity did not directly yield a property indicating the river flowing through it. However, the description of the Grand Canyon entity (wd:Q118841) mentions it is carved by the Colorado River. I will now search for the entity "Colorado River" to confirm its relation to the Grand Canyon.

Top 10 entity alternatives:
1. Colorado River, also known as Rio de Buena Guia, Rio Colorado, Rio Colorado del Norte, Rio Colorado Del Norte, Rio Cosnina (wd:Q1265): major river in the western United States and Mexico
2. Colorado River (wd:Q270627): river in Argentina
3. Brazos River, also known as Los Brazos de Dios, Uhkto'wusi'yohe, Tokonohono, The River of the Arms of God, Rio Trinidad (wd:Q903306): river in Texas, United States

9. Colorado river (wd:Q23649107): watercourse in Chile
10. Colorado River, also known as Rio Colorado (wd:Q5148883): river in Rondônia, Brazil

[Assistant] The entity "Colorado River" that is a major river in the western United States and Mexico is wd:Q1265. Now, I will check if there is a direct statement or property linking the Grand Canyon (wd:Q118841) to the Colorado River (wd:Q1265) to confirm that this river flows through the Grand Canyon.

[Assistant] The direct properties of the Colorado River entity do not explicitly mention the Grand Canyon either. Since the Grand Canyon is known to be carved by the Colorado River, I will now try to find a property that links a river to a canyon or a property that indicates a river flowing through a canyon. I will search for properties with the keyword "flows through" or "flows" to find a suitable property.

3. tributary, also known as has inflow of, affluent, receives tributary, receives river, has river inflow (wd:P974 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): watercourse that flows into an other one (for lake inflows use P200)
4. inflows, also known as inflow, lake inflow, river inflows (wd:P200 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): major inflow sources — rivers, aquifers, glacial runoff, etc. Some terms may not be place names, e.g. none

7. next crossing downstream, also known as downstream crossing adjacent (wd:P2674 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): next crossing of this river, canal, etc. downstream of this subject, followed by
8. crosses, also known as under, tunnel under, through, spanning, over (wd:P177 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): obstacle (body of water, road, railway...) which this bridge (ferry, ford) crosses over or this tunnel goes under
9. located in or next to body of water, also known as located on body of water, ocean, on bay, next to lake, on coast of (wd:P206 as wdtn/wdt/p/pqn/prn/pq/pr/psn/prv/psv/ps/pqv): body of water on or next to which a place is located, location

[Assistant] The property "located in or next to body of water" (wdt:P206) seems relevant as it indicates a body of water on or next to which a place is located. I will check if the Grand Canyon (wd:Q118841) is located on or next to the Colorado River (wd:Q1265) using this property.

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.
