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 the film Red Notice was released?

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

[Tool]
Example 1:
Question:
Who is the editor of Forbes?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q25161472 wdt:P98 ?uri .
}

  ?uri wdt:P31 wd:Q11424 .
  ?uri wdt:P161 wd:Q48410 .
  ?uri wdt:P161 wd:Q40523 .
}

Using entities:

Example 3:
Question:
How many scientists graduated from an Ivy League university?

SPARQL:
SELECT ( COUNT( DISTINCT ?uri ) AS ?c ) WHERE {
  ?uri wdt:P106 wd:Q901 .
  ?uri wdt:P69 ?university .
  wd:Q49113 wdt:P527 ?university .

educated at, also known as graduated from, graduate of, place of education, school attended, schooled at (wd:P69 as wdt): educational institution attended by subject, affiliation

[Assistant]
From the examples, I see that to find the release date of a film, we need to identify the film entity and then find the property related to its release date.

Step 1: Identify the entity for the film "Red Notice."
Step 2: Identify the property for the release date of a film.
Step 3: Query the release date of the film "Red Notice."

I will start by searching for the entity "Red Notice" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Red Notice (wd:Q58815001): 2021 film directed by Rawson Marshall Thurber

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 did World War II officially end?

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

[Tool]
Example 1:
Question:
What is the founding year of the brewery that produces Pilsner Urquell?

SPARQL:
SELECT ?date WHERE {
  wd:Q948831 wdt:P571 ?date .
}

Using entities:
Plzeňský Prazdroj, also known as Měšťanský pivovar Plzeň, Pilsner Urquell Brewery, Plzeňský prazdroj, Plzensky Prazdroj as (wd:Q948831): Czech brewery company

Using properties:
inception, also known as initial release date, founded in, founded on, founded on date, founding date (wd:P571 as wdt): time when an entity begins to exist; for date of official opening use P1619, start time

Example 2:
Question:
Which professional surfers were born in Australia?

SPARQL:
SELECT ( COUNT( DISTINCT ?uri ) AS ?c ) WHERE {
  ?uri wdt:P19 ?birtplace .
  ?birtplace wdt:P17 wd:Q408 .
  ?uri wdt:P106 wd:Q13561328 .

}

Using entities:
association football club, also known as association soccer club, F.C., FC, football club, soccer club (wd:Q476028): sports club devoted to association football (soccer)
Premier League, also known as England Premier League, English Premier League, English Premiership, EPL, PL (wd:Q9448): English men's association football top league

Using properties:

Using properties:
has part(s), also known as has component, incorporates, has ingredient, has ingredients, has member (wd:P527 as wdt): part of this subject; inverse property of "part of" (P361). See also "has parts of the class" (P2670).

Example 3:
Question:
how much is the total population of european union?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q458 wdt:P1082 ?uri .
}

Using entities:

Using properties:
population, also known as inhabitants, human population (wd:P1082 as wdt): number of people inhabiting the place; number of people of subject

[Assistant]
The examples show that to find what something is made of, we can look for the property "has part(s)" (wdt:P527) which indicates the components or ingredients of a subject.

Step 1: Identify the entity for "Fujiyama."
Step 2: Query the property "has part(s)" (wdt:P527) for the entity "Fujiyama" to find what it is made of.

I will start by searching for the entity "Fujiyama" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Mount Fuji, also known as Mt. Fuji, Mt Fuji, Fujiyama, Fuji-yama, Fuji-san (wd:Q39231): volcano in Yamanashi and Shizuoka Prefectures, Japan

10. Tomofumi Fujiyama, also known as Fujiyama Tomofumi (wd:Q38277863): Japanese association football player (1994-), association football player

[Assistant]
The term "Fujiyama" can refer to multiple entities, but the most common and relevant one is Mount Fuji (wd:Q39231), which is also known as Fujiyama. Since the question is about what Fujiyama is made of, it is likely referring to Mount Fuji, the volcano.

Next, I will search for properties related to "composition" or "made of" for the entity Mount Fuji (wd:Q39231). I will search for properties of this entity with a query related to "composition" or "material."

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 question is about the event that killed the most people in the years 1910 to 1920. This implies we are looking for an event (likely a disaster, war, or epidemic) with a high death toll within a specific time range.

Step 1: Identify the property for "number of deaths" or "death toll" related to events.
Step 2: Identify the property for the "start time" and "end time" or "point in time" of the event.
Step 3: Filter events that occurred between 1910 and 1920.
Step 4: Sort by the number of deaths and get the event with the highest number.

I will start by searching for the property related to "number of deaths" or "death toll."

[Tool]
Top 10 property alternatives:
1. number of deaths, also known as dead, qty fatalities, qty deaths, number of fatalities, fatalities (wd:P1120 as pr/wdtn/pq/pqn/pqv/p/prn/psn/wdt/psv/prv/ps): total (cumulative) number of people who died since start as a direct result of an event or cause

10. number of survivors, also known as survivors (wd:P1561 as pr/wdtn/pq/pqn/pqv/p/prn/psn/wdt/psv/prv/ps): number of people surviving an event

[Assistant]
The property "number of deaths" (wdt:P1120) is the most relevant for the death toll of an event.

Next, I will search for properties related to the time of the event, such as "start time," "end time," or "point in time." I want to confirm the exact properties to use for filtering the event's date range.

[Tool]
Top 10 property alternatives:
1. start time, also known as start date, since, valid, join time, joined (wd:P580 as pr/wdtn/pq/pqn/pqv/p/prn/psn/wdt/psv/prv/ps): time an entity begins to exist or a statement starts being valid, point in time

[Assistant]
The property "start time" (wdt:P580) is suitable for the start date of an event.
The property "end time" (wdt:P582) is commonly used as the counterpart to "start time" for the end date of an event.

I will now construct a SPARQL query to find events that have a start time and end time between 1910 and 1920, and order them by the number of deaths (wdt:P1120) in descending order to get the event with the highest death toll. I will limit the result to one event.

I will also include the label of the event for readability.

[Tool]
Got 1 row and 3 columns:
| event         | eventLabel | deaths             |
| ------------- | ---------- | ------------------ |
| wd:Q124001869 |            | 2000 (xsd:decimal) |

[Assistant]
I found an event (wd:Q124001869) that killed 2000 people between 1910 and 1920, but it does not have an English label.

I will now try to get the English label of this event explicitly to provide a more understandable answer.

[Tool] Got no rows and 1 columns

[Assistant]
The event wd:Q124001869 does not have an English label in the knowledge graph.

I will now try to find other events with a high death toll in the years 1910 to 1920 to see if there is a better-known event with a label. I will increase the limit to 5 and check their labels.

[Tool]
Got 5 rows and 3 columns:
| event                                    | eventLabel                       | deaths             |

| Dublin lock-out (wd:Q448920)             | Dublin lock-out (en)             | 2 (xsd:decimal)    |

[Assistant]
The events with the highest death tolls between 1910 and 1920 in the knowledge graph have relatively low numbers compared to historical knowledge (e.g., World War I). The highest recorded death toll in the data is 2000 for an event without an English label.

I will now check if World War I (which occurred from 1914 to 1918) is in the knowledge graph and what its death toll is, as it is historically known to be the deadliest event in that period.

[Tool]
Top 10 entity alternatives:
1. World War I, also known as WWI, WW I, WW1, WW 1, World War One (wd:Q361): global war originating in Europe, 1914–1918
2. Isdud in World War I, also known as Isdud during the first world war (wd:Q132977443)
3. World War I (wd:Q131911377): global way originating in Europe,1914-1918
4. World War I (wd:Q3823675): 2005 video game
5. Information Warfare in World War I (wd:Q55871435): scholarly article by Jonathan Reed Winkler published 2009 in The Journal of Military History
6. World War I Irrupts (wd:Q103811797): scientific article published in 2014
7. World War II, also known as 2nd World War, WWII, WW II, WW2, WW 2 (wd:Q362): 1939–1945 global conflict
8. World War III, also known as 3rd World War, WWIII, WW III, WW3, WW 3 (wd:Q363): hypothetical future global conflict
9. Armistice of Compiègne, also known as Armistice of 11 November 1918, WWI Armistice, World War I Armistice, Armistice of Compiegne (wd:Q253224): armistice during First World War between Allies and Germany
10. causes of World War I, also known as World War I origins, WWI causes, World War I causes, cause of World War I (wd:Q310802): factors that led to the outbreak of World War I

[Assistant] The entity for World War I is wd:Q361. I will now check the number of deaths (wdt:P1120) for World War I.

[Tool]
Got 1 row and 1 column:
| deaths                 |
| ---------------------- |
| 17000000 (xsd:decimal) |

[Assistant]
World War I (wd:Q361) has a recorded death toll of 17,000,000 people, which is significantly higher than the other events found between 1910 and 1920.

I will now finalize the answer stating that World War I is the event that killed the most people in the years 1910 to 1920.

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] In which countries is the Himalayas located?

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

[Tool]
Example 1:
Question:
Give me all films produced by Steven Spielberg with a budget of at least $80 million.

SPARQL:
SELECT DISTINCT ?uri WHERE {
  ?uri wdt:P162 wd:Q8877 ; wdt:P31 / wdt:P279 * wd:Q11424 ; wdt:P2130 ?cost .
  FILTER ( ?cost > 80000000 )
}

Using entities:
film, also known as cinematic work, moving picture, movie, motion pictures, motion picture (wd:Q11424): sequence of images that give the impression of movement, stored on film stock
Steven Spielberg, also known as Steven Allan Spielberg, Spielberg (wd:Q8877): American filmmaker (born 1946), science fiction writer, television producer, executive producer, film screenwriter, businessperson, art collector, film director, film producer, entrepreneur, screenwriter, film editor, film actor, director, producer, writer, actor

Using properties:
producer, also known as music producer, record producer, produced by, film producer, creative producer (wd:P162 as wdt): person(s) who produced the film, musical work, theatrical produc...etc.) [for production company, use P272, video games - use P178]
capital cost, also known as budget, cost, unit cost (wd:P2130 as wdt): amount of money spent on building or producing an object
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
instance of, also known as unitary element of class, has type, unique individual of, type, item of type (wd:P31 as wdt): that class of which this subject is a particular example and mem...is a subclass of mountain (and an instance of volcanic landform)

Example 2:
Question:
Which countries are connected by the Rhine?

SPARQL:
SELECT DISTINCT ?uri ?x ?y WHERE {
  wd:Q584 wdt:P17 ?uri .
  ?uri wdt:P31 wd:Q6256 .
}

Using entities:
Rhine (wd:Q584): river in Western Europe to the North Sea
country, also known as countries (wd:Q6256): distinct territorial body or political entity

Using properties:
country, also known as sovereign state, state, land, host country (wd:P17 as wdt): sovereign state that this item is in (not to be used for human beings), located in the administrative territorial entity
instance of, also known as unitary element of class, has type, unique individual of, type, item of type (wd:P31 as wdt): that class of which this subject is a particular example and mem...is a subclass of mountain (and an instance of volcanic landform)

Example 3:
Question:
What is the highest volcano in Africa?

SPARQL:
SELECT DISTINCT ?s1 WHERE {
  ?s1 wdt:P30 wd:Q15 .
  ?s1 wdt:P31 / wdt:P279 * wd:Q8072 .
  ?s1 wdt:P2044 ?o1 .
}
ORDER BY DESC ( ?o1 )
LIMIT 1

Using entities:
Africa, also known as African continent (wd:Q15): continent
volcano (wd:Q8072): natural, surface vent or fissure usually in a mountainous form

Using properties:
elevation above sea level, also known as MAMSL, MASL, height, elevation above mean sea level, elevation (wd:P2044 as wdt): height of the item (geographical object) as measured relative to sea level
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
continent (wd:P30 as wdt): continent of which the subject is a part, located in/on physical feature
instance of, also known as unitary element of class, has type, unique individual of, type, item of type (wd:P31 as wdt): that class of which this subject is a particular example and mem...is a subclass of mountain (and an instance of volcanic landform)

[Assistant]
From the examples, I see that to find countries where a geographical feature is located, we can use the property "country" (wdt:P17) with the entity representing the geographical feature.

Next, I will search for the entity representing the Himalayas in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Himalayas, also known as Himalaya, Himálaya, Himalaya Mountains, Himálaya Mountains, Himalayan Mountains (wd:Q5451): mountain range in Asia
2. The Himalayas, also known as Himalayas (wd:Q21546296): 2015 film directed by Lee Seok-hoon
3. Himalayas (wd:Q85766587): Welsh rock band
4. Himalayas (wd:Q100353676): painting by Gaganendranath Tagore
5. Himalayas (wd:Q100374811)
6. Himalayas (wd:Q100403347): painting collection of National Gallery of Modern Art, Bangalore
7. Himalayas (wd:Q20441754): painting by Eliot Clark
8. Himalayas (wd:Q20469856): painting by Sidney Nolan
9. Himalayas (wd:Q20469983): painting by Sidney Nolan (AGNSW, 96.1989)
10. Himalayas (wd:L1125498-S1)

[Assistant] The entity "Himalayas" as a mountain range in Asia is wd:Q5451. Now I will find the countries where the Himalayas are located using the property "country" (wdt:P17).
