To answer the question "Who plays Roxanne in Ghost Rider?", I need to identify the movie "Ghost Rider" and the character "Roxanne" in the Freebase knowledge graph. Then, I will find the actor who played this role.

First, let's search for the movie "Ghost Rider" in Freebase.

It seems that the search for the actress in "Ghost Rider" is also not yielding any relevant results. Given this, I will try a more direct approach by searching for the character "Roxanne" and the actress who played her in the movie "Ghost Rider" using a combination of searches and properties.

Given that the search for the character "Roxanne" in the context of the movie "Ghost Rider" is not yielding any results, and the searches for the cast members and the actress are also not providing the necessary information, I will take a different approach.

I will manually construct a SPARQL query to find the actress who played the character "Roxanne" in the movie "Ghost Rider" by querying the cast and roles of the movie.

Let's try the following SPARQL query to find the actress who played Roxanne in "Ghost Rider":

```sparql
SELECT ?actor ?actorLabel
WHERE {
  fb:m.06yykb fb:film.film.cast_member ?performance .
  ?performance fb:film.performance.character ?character .

  FILTER(STR(?characterLabel) = "Roxanne")
  OPTIONAL {
    ?actor rdfs:label ?actorLabel .
    FILTER(LANG(?actorLabel) = "en")
  }
}
```

This query will:
1. Find the cast members of the movie "Ghost Rider" (`fb:m.06yykb`).
2. Identify the character played by each cast member.
3. Filter the results to find the character "Roxanne".
4. Return the actress who played the character "Roxanne".

Let's execute this query.

It seems that the SPARQL query did not return any results, indicating that the character "Roxanne" and the corresponding actress might not be represented in the Freebase knowledge graph in the way I expected.

It seems that the SPARQL query to find the main cast members and their roles in the movie "Ghost Rider" did not return any results. This suggests that the data for the cast and characters of "Ghost Rider" might not be structured in the way I expected in the Freebase knowledge graph.

Given the lack of results, I will try a different approach by searching for the actress who played a significant role in the movie "Ghost Rider" and then manually checking if she played the character "Roxanne."

Let's search for the actress who played a significant role in the movie "Ghost Rider" and see if we can identify the actress who played Roxanne.

I will search for the actress "Eva Mendes," who is known to have played the role of Roxanne in "Ghost Rider."

[Assistant]
From the search results, the most relevant entry for the actress "Eva Mendes" is the first one: `fb:m.03_x5t`.

Now, let's verify if Eva Mendes played the character "Roxanne" in the movie "Ghost Rider" by checking the roles she played in the movie.

I will construct a SPARQL query to find the roles played by Eva Mendes in the movie "Ghost Rider" and see if one of them is "Roxanne."

```sparql

This query will:
1. Find the cast members of the movie "Ghost Rider" (`fb:m.06yykb`).
2. Identify the roles played by Eva Mendes (`fb:m.03_x5t`).
3. Return the character and the character label.

The top result for "Hank Baskett" is the American football player Henry Randall "Hank" Baskett III (fb:m.0d81yf). Now, let's find out what team he was on in 2010. We need to look for a property that indicates the team he played for and filter it by the year 2010.

Let's search for the property that indicates the team he played for.

[Tool]
Top 10 property alternatives:
1. Teams (fb:sports.pro_athlete.teams): Sports team roster, Athlete
2. Name (fb:type.object.name): Object, Text
3. Key (fb:type.object.key): Object, Key
4. Position (fb:user.szaijan.fantasy_football.player.position): Position, Player
5. Games (fb:american_football.football_player.games): American football player, Player Game Statistics
6. Official website (fb:common.topic.official_website): Topic, URI
7. Article (fb:common.topic.article): Document, Topic
8. Country of nationality (fb:people.person.nationality): Country, Person
9. Description (fb:common.topic.description): Topic, Text
10. Profession (fb:people.person.profession): Profession, Person

[Assistant]
The property "Teams" (fb:sports.pro_athlete.teams) seems to be the most relevant for finding out the team Hank Baskett played for. Now, let's construct a SPARQL query to find the team he was on in 2010.

We will use the `fb:sports.pro_athlete.teams` property and filter the results by the year 2010.

Let's execute the query:

```sparql
SELECT ?team
WHERE {
  fb:m.0d81yf fb:sports.pro_athlete.teams ?teamMembership .
  ?teamMembership fb:sports.sports_team_roster.from_year ?year .
  FILTER(?year <= 2010)
  ?teamMembership fb:sports.sports_team_roster.to_year ?toYear .
  FILTER(?toYear >= 2010)
  ?teamMembership fb:sports.sports_team_roster.team ?team .
}
```

This query will find the team membership for Hank Baskett where the year range includes 2010.

Let's execute this query.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that the query did not return any results, which suggests that there might be no team membership record for Hank Baskett in 2010 in the Freebase dataset. However, let's try a slightly different approach to ensure we are not missing anything.

We can try to find the team directly associated with Hank Baskett without filtering by the year initially, and then check if there is any information about the year.

Let's execute a simpler query to find the teams Hank Baskett has been associated with:

```sparql
SELECT ?team
WHERE {
  fb:m.0d81yf fb:sports.pro_athlete.teams ?teamMembership .
  ?teamMembership fb:sports.sports_team_roster.team ?team .
}
```

This query will list all the teams Hank Baskett has been associated with, and we can then check if any of these teams correspond to the year 2010.

Let's execute this query.

[Tool]
Got 5 rows and 1 column:
| ?team                            |
| -------------------------------- |
| Minnesota Vikings (fb:m.051q5)   |
| Minnesota Vikings (fb:m.051q5)   |
| Philadelphia Eagles (fb:m.05tg3) |
| Indianapolis Colts (fb:m.03wnh)  |
| Philadelphia Eagles (fb:m.05tg3) |

[Assistant]
The query returned multiple teams that Hank Baskett has been associated with, including the Minnesota Vikings, Philadelphia Eagles, and Indianapolis Colts. To determine which team he was on in 2010, we need to filter these results by the year 2010.

Let's refine our query to include the year filter again, but this time we will explicitly check the `from_year` and `to_year` properties for each team membership to see if they include 2010.

Here is the refined query:

```sparql
SELECT ?team
WHERE {
  fb:m.0d81yf fb:sports.pro_athlete.teams ?teamMembership .
  ?teamMembership fb:sports.sports_team_roster.team ?team .
  ?teamMembership fb:sports.sports_team_roster.from_year ?fromYear .
  ?teamMembership fb:sports.sports_team_roster.to_year ?toYear .
  FILTER(?fromYear <= 2010 && ?toYear >= 2010)
}
```

This query will filter the team memberships to only those that include the year 2010.

Let's execute this query.

[Tool] Got no rows and 1 columns

[Assistant]
It seems that even with the refined query, there are no results indicating that Hank Baskett was on any team in 2010 according to the Freebase dataset. This could mean that the data for 2010 is not available or that Hank Baskett was not actively playing in the NFL during that year.

Given the lack of results, we can conclude that the Freebase dataset does not provide the information needed to answer the question accurately.

I will provide a final answer stating that the data is not available in the Freebase dataset.

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.

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 language do they speak in malta?

[Assistant] To answer the question about the language spoken in Malta, I need to identify the entity for Malta and then find the property that indicates the official or commonly spoken languages of a country. Let's start by searching for the entity representing Malta.

[Assistant]
The properties "Languages spoken" (fb:location.country.languages_spoken) and "Official Language" (fb:location.country.official_language) seem relevant for finding the languages spoken in Malta. I will use these properties in a SPARQL query to retrieve the languages.

Let's start with the "Official Language" property:

```sparql
SELECT ?language WHERE {
  fb:m.04v3q fb:location.country.official_language ?language .
}
```

I will execute this query to see the results.

[Tool]
Got 2 rows and 1 column:
| ?language                       |
| ------------------------------- |
| English Language (fb:m.02h40lc) |
| Maltese Language (fb:m.04t3_)   |

[Assistant]
The query returned the official languages of Malta, which are English (fb:m.02h40lc) and Maltese (fb:m.04t3_).

Next, I will check if there are any additional languages spoken in Malta using the "Languages spoken" property:

```sparql
SELECT ?language WHERE {
  fb:m.04v3q fb:location.country.languages_spoken ?language .
}
```

I will execute this query to see if it returns any additional languages.

[Tool]
Got 1 row and 1 column:
| ?language                       |
| ------------------------------- |
| English Language (fb:m.02h40lc) |

[Assistant]
The query for "Languages spoken" returned only English (fb:m.02h40lc), which is already included in the official languages. Therefore, the official languages of Malta are the primary languages spoken in the country.

To provide a clear and concise answer, I will combine the results and format them appropriately.

Here is the final SPARQL query and answer:

```sparql
SELECT ?language WHERE {
  VALUES ?property { fb:location.country.official_language fb:location.country.languages_spoken }
  fb:m.04v3q ?property ?language .
}
```

The languages spoken in Malta are English and Maltese.

| fb:m.0clxxj1 |

[Assistant]
The query returned an identifier for the geolocation of the Gobi Desert, `fb:m.0clxxj1`. To get the actual coordinates, we need to query for the latitude and longitude of this geolocation.

Let's find the latitude and longitude properties and then use them in a SPARQL query.

4. Type (fb:type.object.type): Object, Type

No other items found

[Assistant] The properties `fb:location.geocode.latitude` and `fb:location.geocode.longitude` are the ones we need to get the coordinates. Let's construct a SPARQL query to retrieve both the latitude and longitude for the geolocation of the Gobi Desert.

[Tool]
Got 1 row and 2 columns:
| ?latitude | ?longitude |
| --------- | ---------- |
| 42.59     | 103.43     |

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] who is michael j fox wife?

[Assistant] To answer the question about who Michael J. Fox's wife is, I'll start by searching for Michael J. Fox in the Freebase knowledge graph to find his identifier. Once I have his identifier, I can look for the property that indicates his spouse or wife.

[Tool]
Top 10 entity alternatives:
1. Michael J. Fox, also known as Joe Rasnick, Mike Fox, Mike, Michael J. Fox, OC, Michael J. Fox (fb:m.0hz_1): Michael Andrew Fox, OC, known as Michael J. Fox, is a Canadian-A...e years for his recurring role as crafty attorney Louis Canning., Celebrity

10. Michael J. Fox (fb:m.011hxr0): Musical Recording

No other items found

[Assistant] The top result for Michael J. Fox is `fb:m.0hz_1`. Now, I will search for the property that indicates his spouse or wife. I expect it to be something like "spouse" or "wife".

[Tool]
Top 10 property alternatives:
1. Spouse (or domestic partner) (fb:people.person.spouse_s): Marriage, Person
2. Profession (fb:people.person.profession): Profession, Person
3. Country of nationality (fb:people.person.nationality): Country, Person
4. Gender (fb:people.person.gender): Person, Gender
5. Name (fb:type.object.name): Object, Text
6. Member of (fb:music.group_member.membership): Musical Group Membership, Musician
7. Date of birth (fb:people.person.date_of_birth): Date/Time, Person

10. Place of birth (fb:people.person.place_of_birth): Location, Person

No other items found

[Assistant]
The property `fb:people.person.spouse_s` seems to be the correct one for indicating Michael J. Fox's spouse. Now, I will construct a SPARQL query to find out who his wife is.

Let's execute the query:

```sparql
SELECT ?wife ?wifeLabel
WHERE {
  fb:m.0hz_1 fb:people.person.spouse_s ?wife .
  OPTIONAL { ?wife rdfs:label ?wifeLabel }
}
```

This query will return the IRI of Michael J. Fox's wife and optionally her label.

[Tool]
Got 1 row and 2 columns:
| ?wife        | ?wifeLabel |
| ------------ | ---------- |
| fb:m.02kkmrn |            |

[Assistant]
The query returned the IRI `fb:m.02kkmrn` for Michael J. Fox's wife, but the label is missing. To get more information about this person, I will run another query to fetch the label and any other relevant details.

Let's execute the following query:

```sparql
SELECT ?wife ?wifeLabel
WHERE {
  fb:m.02kkmrn rdfs:label ?wifeLabel .
}
```

This query will return the label for the IRI `fb:m.02kkmrn`.

[Tool] Got no rows and 2 columns

[Assistant]
It appears that the label for the IRI `fb:m.02kkmrn` is not available in the Freebase knowledge graph. However, we can still provide the IRI as the answer.

To finalize the answer, I will use the IRI `fb:m.02kkmrn` and note that the label is not available.

Here is the final SPARQL query and answer:

```sparql
SELECT ?wife
WHERE {
  fb:m.0hz_1 fb:people.person.spouse_s ?wife .
}
```

The answer to the question "Who is Michael J. Fox's wife?" is `fb:m.02kkmrn`.

[Assistant]
It seems that even searching for the character "Meg" in "Family Guy" is not yielding any results. Given the constraints and the lack of results, it might be that the specific information about the voice actor for Meg in Season 1 of "Family Guy" is not available in Freebase.

### Conclusion
Since the search for the character "Meg" and the voice actor associated with her in "Family Guy" did not yield any results, I will have to conclude that the information is not available in the Freebase knowledge graph.

I will provide my best attempt at a SPARQL query and explain why it did not work.

### Best Attempt at SPARQL Query
```sparql
PREFIX fb: <http://rdf.freebase.com/ns/>

SELECT ?voiceActor
WHERE {
  fb:m.027gynh fb:film.film.cast_member ?performance .
  ?performance fb:film.performance.character ?character .
  ?character rdfs:label "Meg"@en .
  ?performance fb:film.performance.actor ?voiceActor .
}
```

This query attempts to find the voice actor who played the character "Meg" in Season 1 of "Family Guy" (`fb:m.027gynh`). However, the search for the character "Meg" and the associated performance did not yield any results, indicating that the data is not present in Freebase.

### Explanation
The information about the voice actor for Meg in Season 1 of "Family Guy" is not available in the Freebase knowledge graph. Therefore, I cannot provide a SPARQL query that returns the correct answer.

I will now call the `cancel` function to indicate that I could not find a satisfactory SPARQL query.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:

qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 year did houston rockets win their first championship?

[Assistant]
The property "Championships" (fb:sports.sports_team.championships) seems to be the most relevant for finding the championships won by the Houston Rockets. Now, I will construct a SPARQL query to retrieve the years when the Houston Rockets won their championships.

Let's start with a simple query to see if we can get the championship events:

```sparql
SELECT ?championship
WHERE {
  fb:m.0jmfb fb:sports.sports_team.championships ?championship .
}
```

I will execute this query to see the results.

[Tool]
Got 2 rows and 1 column:
| ?championship                 |
| ----------------------------- |
| 1994 NBA Finals (fb:m.08x9cq) |
| 1995 NBA Finals (fb:m.08x9k6) |

[Assistant]
The query returned the championship events for the Houston Rockets, specifically the 1994 and 1995 NBA Finals. To determine the year of their first championship, I need to extract the year from these events. I will now refine the query to include the year of each championship event.

I will use the `rdfs:label` property to get the label of the championship event, which typically includes the year. Here is the updated query:

```sparql
SELECT ?championship ?year
WHERE {
  fb:m.0jmfb fb:sports.sports_team.championships ?championship .
  ?championship rdfs:label ?label .
  BIND(SUBSTR(?label, 1, 4) AS ?year)
}
ORDER BY ASC(?year)
LIMIT 1
```

This query will return the year of the first championship won by the Houston Rockets. Let's execute it.

[Tool]
Got 1 row and 2 columns:
| ?championship                 | ?year |
| ----------------------------- | ----- |
| 1994 NBA Finals (fb:m.08x9cq) | 1994  |

[Assistant]
The query has successfully returned the year of the first championship won by the Houston Rockets, which is 1994.

Therefore, the Houston Rockets won their first championship in 1994.

Here is the final SPARQL query and answer:

```sparql
SELECT ?championship ?year
WHERE {
  fb:m.0jmfb fb:sports.sports_team.championships ?championship .
  ?championship rdfs:label ?label .
  BIND(SUBSTR(?label, 1, 4) AS ?year)
}
ORDER BY ASC(?year)
LIMIT 1
```

Answer: The Houston Rockets won their first championship in 1994.
