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:

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.

[Assistant]
From the similar examples, the approach is to:

1. Identify the entity for "Roxanne" (the character) in "Ghost Rider".
2. Identify the entity for "Ghost Rider" (the film).
3. Use the properties related to film performances, such as:
   - fb:film.film.starring (the starring performances in a film)
   - fb:film.performance.actor (the actor in a performance)
   - fb:film.performance.character (the character in a performance)

The query structure will be similar to the examples for "Mary Jane" in "Spider-Man 2".

First, I will search for the entity for "Roxanne" in Freebase.

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 team is hank baskett on 2010?

Using entities:
Hank Baskett, also known as Henry Randall Baskett III (fb:m.0d81yf): Henry Randall "Hank" Baskett III is a former American football w...have co-starred on another show, Kendra on Top, since June 2012., has type American football player

Team (fb:sports.sports_team_roster.team): part of Sports team roster schema, links to type Sports Team
To (fb:sports.sports_team_roster.to): part of Sports team roster schema, links to type Date/Time

[Assistant]
The similar examples provide a clear pattern for how to answer this question. The entity for Hank Baskett is `fb:m.0d81yf`. The relevant properties are:
- `fb:sports.pro_athlete.teams` (links athlete to team roster)
- `fb:sports.sports_team_roster.team` (links roster to team)
- `fb:sports.sports_team_roster.from` and `fb:sports.sports_team_roster.to` (date range for the roster)

We need to find the team(s) Hank Baskett was on during 2010, i.e., where the roster's "from" date is before or during 2010 and the "to" date is after or during 2010.

To make the answer more readable, I'll also try to include the team's label if available.

Let's construct the SPARQL query accordingly.

[Tool] Got no rows and 2 columns

[Assistant]
The query returned no results. This could be due to several reasons: the date format may not match what's in Freebase, or the properties might be slightly different than expected. Let's check what values are actually present for Hank Baskett's team rosters, especially the date properties, to debug further.

First, let's list all properties and values for Hank Baskett's team roster entries.

[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:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#
rdfs: <http://www.w3.org/2000/01/rdf-schema#
owl: <http://www.w3.org/2002/07/owl#
xsd: <http://www.w3.org/2001/XMLSchema#
foaf: <http://xmlns.com/foaf/0.1/
skos: <http://www.w3.org/2004/02/skos/core#
dct: <http://purl.org/dc/terms/
dc: <http://purl.org/dc/elements/1.1/
prov: <http://www.w3.org/ns/prov#
schema: <http://schema.org/
geo: <http://www.opengis.net/ont/geosparql#
geosparql: <http://www.opengis.net/ont/geosparql#

hint: <http://www.bigdata.com/queryHints#
wikibase: <http://wikiba.se/ontology#
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 language do they speak in malta?

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

[Tool]
Example 1:
Question:
what language do the speak in switzerland?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.06mzp ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.06mzp fb:location.country.official_language ?x .
}

Using entities:
Switzerland, also known as La Suisse, Swiss Confederation, Svizzera, Svizra, Schweiz (fb:m.06mzp): Switzerland, officially the Swiss Confederation, is a country in...nally since 1815—and did not join the United Nations until 2002., has type Country

Using properties:
Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema

Example 2:
Question:
what language do the speak in switzerland?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.06mzp ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.06mzp fb:location.country.languages_spoken ?x .
}

Using entities:
Switzerland, also known as La Suisse, Swiss Confederation, Svizzera, Svizra, Schweiz (fb:m.06mzp): Switzerland, officially the Swiss Confederation, is a country in...nally since 1815—and did not join the United Nations until 2002., has type Country

Using properties:
Languages spoken (fb:location.country.languages_spoken): links to type Human Language, part of Country schema

Example 3:
Question:
what to see and do in malta?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.04v3q ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.04v3q fb:travel.travel_destination.tourist_attractions ?x .
}

Using entities:
Malta, also known as Republic of Malta, Isla de Malta (fb:m.04v3q): Malta, officially the Republic of Malta, is a Southern European .... The George Cross continues to appear on Malta's national flag., has type Country

Using properties:
Tourist attractions (fb:travel.travel_destination.tourist_attractions): part of Travel destination schema, links to type Tourist attraction

[Assistant]
From the similar examples, I see that:

- The Freebase entity for Malta is fb:m.04v3q.
- For Switzerland, the properties used to get languages are fb:location.country.official_language and fb:location.country.languages_spoken.

I will use both properties to ensure completeness. I will write a query to get all languages spoken in Malta using both properties, returning the language IRIs and optionally their labels.

Let's proceed step by step:
1. Write a query to get the official languages of Malta.
2. Write a query to get the languages spoken in Malta.
3. Combine results and add optional labels.

First, let's confirm the properties for Malta.

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:
fb: <http://rdf.freebase.com/ns/

wikibase: <http://wikiba.se/ontology#
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] where are the gobi desert located on a map?

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

[Tool]
Example 1:
Question:
where is the gobi desert located?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0ff0d ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0ff0d fb:location.location.containedby ?x .
}

Using entities:
Gobi Desert (fb:m.0ff0d): The Gobi is a large desert region in Asia. It covers parts of no...g clouds from the Indian Ocean from reaching the Gobi territory., has type Geographical Feature

Using properties:
Contained by (fb:location.location.containedby): part of Location schema, links to type Location

Example 2:
Question:
where is burundi located on a map?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0169t ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0169t fb:location.location.containedby ?x .
}

Using entities:
Burundi (fb:m.0169t): Burundi, officially the Republic of Burundi, is a landlocked cou... in the establishment of a republic and one-party state in 1966., has type Country

Using properties:
Contained by (fb:location.location.containedby): part of Location schema, links to type Location

Example 3:
Question:
where is burundi located on a map?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0169t ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0169t fb:base.locations.countries.continent ?x .
}

Using entities:
Burundi (fb:m.0169t): Burundi, officially the Republic of Burundi, is a landlocked cou... in the establishment of a republic and one-party state in 1966., has type Country

Using properties:
Continent (fb:base.locations.countries.continent): links to type Continents, part of Countries schema

[Assistant]
From the similar examples, the Gobi Desert entity in Freebase is fb:m.0ff0d. The property fb:location.location.containedby is used to find the larger locations that contain the Gobi Desert, which is a good way to answer "where is the Gobi Desert located?"

However, the user also asked about "on a map," which could imply geographic coordinates or a map location. To provide a more precise answer, I will also look for properties related to geographic coordinates for the Gobi Desert entity.

First, I will search for properties related to "coordinate" for the Gobi Desert entity.

[Assistant]
From the similar examples, I see that Michael J. Fox's Freebase entity is fb:m.0hz_1. The property for "wife" is likely related to "spouse" or "marriage".

Next, I will search for properties related to "spouse" or "wife" for Michael J. Fox in Freebase.

[Assistant]
The property fb:people.person.spouse_s is the most relevant for "spouse (or domestic partner)", and it links to a type Marriage. To find Michael J. Fox's wife, I need to follow this property and then extract the spouse's identity from the Marriage entity.

Next, I will list some triples where Michael J. Fox is the subject and the property is fb:people.person.spouse_s to see how the data is structured.

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:

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] when does the vietnam war end?

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

[Tool]
Example 1:
Question:
what year did the vietnam war happen?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07_nf ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07_nf fb:time.event.start_date ?x .
}

Using entities:
Vietnam War, also known as American War, Vietnam Conflict, Second Indochina War (fb:m.07_nf): The Vietnam War, also known as the Second Indochina War, and als... operations, involving ground forces, artillery, and airstrikes., has type Military Conflict

Using properties:
Start date (fb:time.event.start_date): links to type Date/Time, part of Event schema

Example 2:
Question:
what countries was the vietnam war between?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07_nf ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07_nf fb:military.military_conflict.combatants ?y .
  ?y fb:military.military_combatant_group.combatants ?x .
}

Using entities:
Vietnam War, also known as American War, Vietnam Conflict, Second Indochina War (fb:m.07_nf): The Vietnam War, also known as the Second Indochina War, and als... operations, involving ground forces, artillery, and airstrikes., has type Military Conflict

Using properties:
Combatants (fb:military.military_combatant_group.combatants): part of Military combatant group schema, links to type Military Combatant
Combatants (fb:military.military_conflict.combatants): links to type Military combatant group, part of Military Conflict schema

Example 3:
Question:
where was the vietnam war located?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07_nf ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07_nf fb:time.event.locations ?x .
}

Using entities:
Vietnam War, also known as American War, Vietnam Conflict, Second Indochina War (fb:m.07_nf): The Vietnam War, also known as the Second Indochina War, and als... operations, involving ground forces, artillery, and airstrikes., has type Military Conflict

Using properties:
Location(s) (fb:time.event.locations): links to type Location, part of Event schema

[Assistant]
From the similar examples, I see that the entity for the Vietnam War is fb:m.07_nf. The property for the start date is fb:time.event.start_date. Since you are asking about the end date, I need to find the corresponding property for the end date of an event.

I'll search for properties related to "end date" for the Vietnam War entity.

[Tool]
Top 10 property alternatives:
1. End date (fb:time.event.end_date): links to type Date/Time, part of Event schema
2. Start date (fb:time.event.start_date): links to type Date/Time, part of Event schema
3. Includes event (fb:time.event.includes_event): part of Event schema, links to type Event
4. Included in event (fb:time.event.included_in_event): part of Event schema, links to type Event
5. Key (fb:type.object.key): part of Object schema, links to type Key
6. Event type (fb:base.culturalevent.event.event_type): part of event schema, links to type Text
7. entity involved (fb:base.culturalevent.event.entity_involved): part of event schema, links to type Topic
8. Location(s) (fb:time.event.locations): links to type Location, part of Event schema
9. entry (fb:user.tsegaran.random.taxonomy_subject.entry): part of Taxonomy Subject schema, links to type Taxonomy Entry
10. Image (fb:common.topic.image): part of Topic schema, links to type Image

No other items found

[Assistant] The property fb:time.event.end_date is the most relevant for finding the end date of the Vietnam War. I will now construct a SPARQL query to retrieve the end date for the Vietnam War (fb:m.07_nf) using this property.

[User] what region of the world is egypt associated with?

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

[Tool]
Example 1:
Question:
what countries are around egypt?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.02k54 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.02k54 fb:location.location.adjoin_s ?y .
  ?y fb:location.adjoining_relationship.adjoins ?x .
  ?x fb:common.topic.notable_types fb:m.01mp .
}

Using entities:
Country, also known as Empire (fb:m.01mp): The type country in Freebase can and should be used with a varie...s with little population or autonomy will be typed as a country.
Egypt, also known as Arab Republic of Egypt (fb:m.02k54): Egypt, officially the Arab Republic of Egypt, is a transcontinen...ater Cairo, Alexandria and other major cities in the Nile Delta., has type Country

Using properties:
Notable types (fb:common.topic.notable_types): part of Topic schema, links to type Type
Adjoins (fb:location.adjoining_relationship.adjoins): part of Adjoining Relationship schema, links to type Location
Adjoins (fb:location.location.adjoin_s): links to type Adjoining Relationship, part of Location schema

Example 2:
Question:
what region of the world is north america in?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.059g4 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.059g4 fb:location.location.containedby ?x .
}

Using entities:
North America (fb:m.059g4): North America is a continent wholly within the Northern Hemisphe... ago. The Classic stage spans roughly the 6th to 13th centuries., has type Continent

Using properties:
Contained by (fb:location.location.containedby): part of Location schema, links to type Location

Example 3:
Question:
where do most of the people in egypt live?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.02k54 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.02k54 fb:location.location.contains ?x .
  ?x fb:topic_server.population_number ?sk0 .
}
ORDER BY DESC ( xsd:float ( ?sk0 ) )
LIMIT 1

Using entities:
Egypt, also known as Arab Republic of Egypt (fb:m.02k54): Egypt, officially the Arab Republic of Egypt, is a transcontinen...ater Cairo, Alexandria and other major cities in the Nile Delta., has type Country

Using properties:
Contains (fb:location.location.contains): part of Location schema, links to type Location

[Assistant]
From the similar examples, especially Example 2 ("what region of the world is north america in?"), it appears that the property fb:location.location.containedby is used to find the broader region or container of a location entity.

Let's verify the entity for Egypt and then use the containedby property to find its associated region.

[Tool]
Top 10 entity alternatives:
1. Egypt, also known as Arab Republic of Egypt (fb:m.02k54): Egypt, officially the Arab Republic of Egypt, is a transcontinen...ater Cairo, Alexandria and other major cities in the Nile Delta., has type Country
2. Egypt (fb:m.02hf3z): The Roman province of Egypt was established in 30 BC after Octav...an economy. Aegyptus was by far the most wealthy Roman province., has type Location
3. Egypt, also known as Egypt, Arkansas, Craighead County / Egypt town (fb:m.0qskb): Egypt is a town in Craighead County, Arkansas, United States. Th...cluded in the Jonesboro, Arkansas Metropolitan Statistical Area., has type City/Town/Village
4. Government of Egypt, also known as Egypt (fb:m.05z01q3): has type Government
5. Egypt (fb:m.08msz0): Egypt is a BBC television drama serial about various archaeologi... Timeless Histories by Chappell music, produced by Clare Isaacs., has type TV Program
6. Egypt, also known as Egypt, Pennsylvania (fb:m.047ln88): Egypt is an unincorporated community in Whitehall Township, Lehi...e Point. The population of Egypt is 2,391 as of the 2010 census., has type City/Town/Village
7. Egypt, also known as Egypten: 1156 f.Kr. Faraos Hemlighet, Egypte 1156 voor Christus: Het raadsel van de koninklijke tombe, Egypte 1156 av. J.-C.: L'énigme de la tombe royale, Egypt 1156 BC: Tomb of the Pharaoh, Egypt 1156 aC: L'Enigma della Tomba Reale (fb:m.04y6gbb): Egypt: 1156 B.C.: Tomb of the Pharaoh is a 1999 adventure video ...t 2: The Heliopolis Prophecy and Egypt 3: The Egyptian Prophecy., has type Video game

9. Egypt (fb:m.01mqqv2): There is/has been more than one band called Egypt over the years... days, making many people believe they were two different bands., has type Musical Group
10. Egypt (fb:m.0frlcr7): has type Musical Group

[Assistant]
The correct entity for the country Egypt is fb:m.02k54. Based on the similar example, we should use the property fb:location.location.containedby to find the region Egypt is associated with.

I will now construct a SPARQL query to find the regions (or broader locations) that contain Egypt.
