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 businesses are founded by the person in charge of Tesla?

[Assistant]
Okay, let's break this down. First, I need to find the person in charge of Tesla. Then, I need to find businesses founded by that person.

Here's my plan:

1.  Search for "person in charge of Tesla" to identify the relevant entity.
2.  Find the "founder" property.
3.  Find the businesses founded by the person identified in step 1.

Let's start by searching for the person in charge of Tesla.

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 swordfighter in the lord of the rings marry a half-elven and belong to rangers of the north?

[Assistant]
Okay, let's break this down. We need to find a swordfighter from Lord of the Rings who married a half-elven and is a member of the Rangers of the North.

1.  **Find swordfighters in Lord of the Rings:** We can start by searching for "Lord of the Rings" and "swordfighter" to see if we can identify relevant entities and properties.
2.  **Find half-elven characters:** We can search for "half-elven" to identify relevant entities.
3.  **Find Rangers of the North:** We can search for "Rangers of the North" to identify relevant entities.
4.  **Combine the information:** We can then combine these pieces of information to construct a SPARQL query that retrieves the desired entity.

Let's start by searching for "Lord of the Rings" to get the Wikidata entity.

[Assistant] `characters (wd:P674)` looks promising. Let's use this to find characters in Lord of the Rings.

[Tool] Got no rows and 3 columns

[Assistant]
That didn't work. It seems like the property `characters` is used the other way around. Let's try to find instances of characters that appear in the Lord of the Rings. We can use `instance of (wdt:P31)` to find characters and `characters (wdt:P674)` to link them to the Lord of the Rings.

Since we don't have a direct property for "swordfighter", we can look for characters who have a property related to weapons or fighting. Let's start by finding characters in the Lord of the Rings and then explore their properties.

```sparql
SELECT ?character WHERE {
  ?character wdt:P674 wd:Q15228.
  ?character wdt:P31 wd:Q5 . # Q5 is human
}
```
I'm adding the `wdt:P31 wd:Q5` to filter for humans.

[Tool] Got no rows and 1 columns

[Assistant] It seems like `wdt:P674` is not the correct property to link characters to the Lord of the Rings. Let's try to find the "main subject" of the Lord of the Rings and then find characters related to that subject.

[Tool] Got no rows and 3 columns

[Assistant] Okay, let's try a different approach. Let's search for "character in Lord of the Rings" to see if we can find a specific category or instance.

Let's try to find the instances using a SPARQL query.
```sparql

}
```

[Tool] Got no rows and 1 columns

[Assistant] It seems like we are having trouble finding the characters directly linked to "Lord of the Rings". Let's try to find some known characters and then work our way backward. We know Aragorn is a character in Lord of the Rings, a swordfighter, and a Ranger of the North. Let's search for Aragorn.

[Tool]
Top 10 entity alternatives:
1. Aragorn, also known as Strider, Thorongil, Telcontar, Elessar, Aragorn II (wd:Q180322): fictional character from J.R.R. Tolkien's legendarium, military leader, swordfighter

10. Aragorn Place, also known as Aragon Place (wd:Q110528035): residential street

[Assistant] Okay, we found Aragorn (wd:Q180322). Now let's check if he is a swordfighter, married to a half-elven, and a Ranger of the North. We can use `instance of (wdt:P31)` to check if he is a swordfighter, `spouse (wdt:P26)` to check his spouse, and search for properties related to "Ranger of the North".

[Assistant] We can see that Aragorn is a "military leader (wd:Q1402561)" and "King of the Reunited Kingdom (wd:Q16594772)". Let's check his spouse.

[Tool]
Got 1 row and 3 columns:
| subject              | property         | object             |
| -------------------- | ---------------- | ------------------ |
| Aragorn (wd:Q180322) | spouse (wdt:P26) | Arwen (wd:Q206018) |

[Assistant] Aragorn's spouse is Arwen (wd:Q206018). Let's check if Arwen is a half-elf.

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

| Arwen (wd:Q206018) | instance of (wdt:P31) | literary character (wd:Q3658341)       |
| Arwen (wd:Q206018) | instance of (wdt:P31) | fantasy film character (wd:Q117289741) |

[Assistant] Arwen is indeed a half-elven (wd:Q2035494). Now we need to confirm that Aragorn is a swordfighter and a Ranger of the North. We already know he is a military leader. Let's search for "sword" related properties for Aragorn.

[Tool]
Top 10 property alternatives:
1. armament, also known as armed with, ship armament, weapon, wields (wd:P520 as wdt/p): equippable weapon item for the subject, has facility
2. instance of, also known as unitary element of class, has type, unique individual of, type, item of type (wd:P31 as wdt/p): that class of which this subject is a particular example and mem...is a subclass of mountain (and an instance of volcanic landform)

No other items found

[Assistant] `armament (wdt:P520)` seems relevant. Let's see if Aragorn has a sword as armament.

[Tool]
Got 2 rows and 3 columns:
| subject              | property            | object                 |
| -------------------- | ------------------- | ---------------------- |
| Aragorn (wd:Q180322) | armament (wdt:P520) | Narsil (wd:Q20149)     |
| Aragorn (wd:Q180322) | armament (wdt:P520) | Andúril (wd:Q14917772) |

[Assistant]
Aragorn has Narsil and Andúril as armaments, which are swords. So, he is a swordfighter.

Now, let's check if he is a Ranger of the North. We can try to find a statement about his affiliation or membership. Since we couldn't find a direct property, let's use a SPARQL query to search for any statements that connect Aragorn to "Ranger" or "Rangers of the North".
```sparql
SELECT ?property ?object WHERE {
  wd:Q180322 ?property ?object.
  FILTER (CONTAINS(LCASE(STR(?object)), "ranger"))
}
```

[Tool] Got no rows and 2 columns

[Assistant] Let's try searching for "Rangers of the North" directly.

[Tool]
Top 10 entity alternatives:
1. Rangers of the North (wd:Q2292830): Human group from J. R. R. Tolkien's legendarium
2. Rangers of the North: The Kingdom of Arthedain (wd:Q65058758)

10. Norm of the North (wd:Q16253705): 2016 film directed by Trevor Wall

[Assistant] We found Rangers of the North (wd:Q2292830). Let's see if we can link Aragorn to this entity.

[Tool]
Top 10 property alternatives:
1. child, also known as has son, kids, mother of, kid, issue (wd:P40 as wdt/p): subject has object as child. Do not use for stepchildren—use "relative" (P1038), qualified with "type of kinship" (P1039), significant person, relative

No other items found

[Assistant]
Let's try a SPARQL query to find if Aragorn is a member of the Rangers of the North.
```sparql
SELECT ?property WHERE {
  wd:Q180322 ?property wd:Q2292830.
}
```

[Tool]
Got 1 row and 1 column:
| ?property               |
| ----------------------- |
| ethnic group (wdt:P172) |

[Assistant]
Okay, Aragorn's `ethnic group (wdt:P172)` is Rangers of the North (wd:Q2292830).

So, Aragorn is a swordfighter, married to a half-elven (Arwen), and belongs to the Rangers of the North.

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.
