This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Input: Consider Input: Passage: In the USA an estimate was found of 32,500 children (<21 years) that suffer from major paediatric amputation, with 5,525 new cases each year, of which 3,315 congenital. Carr et al. (1998) investigated amputations caused by landmines for Afghanistan, Bosnia and Herzegovina, Cambodia and Mozambique among children (<14 years), showing estimates of respectively 4.7, 0.19, 1.11 and 0.67 per 1000 children. Mohan (1986) indicated in India a total of 424,000 amputees (23,500 annually), of which 10.3% had an onset of disability below the age of 14, amounting to a total of about 43,700 limb deficient children in India alone.

Output: How many amputees in India in all are not children?


Input: Consider Input: Passage: The 8,878 housing units averaged 685.5 per square mile (264.7/km²), of which 6,287 (73.6%) were owner-occupied, and 2,256 (26.4%) were occupied by renters. The homeowner vacancy rate was 1.2%; the rental vacancy rate was 5.2%.  Around 17,769 people (77.1% of the population) lived in owner-occupied housing units and 5,280 people (22.9%) lived in rental housing units.

Output: How many more housing units were owner-occupied than occupied by renters?


Input: Consider Input: Passage: Until the 1950s, the acoustic, nylon-stringed classical guitar was the only type of guitar favored by classical, or art music composers. In the 1950s a few Contemporary classical music composers began to use the electric guitar in their compositions. Examples of such works include Luciano Berios Nones (Berio) (1954) Karlheinz Stockhausens Gruppen (Stockhausen) (1955–57); Donald Erbs String Trio (1966), Morton Feldmans The Possibility of a New Work for Electric Guitar (1966); George Crumbs Songs, Drones, and Refrains of Death (1968); Hans Werner Henzes Versuch über Schweine (1968); Francis Thornes Sonar Plexus (1968) and Liebesrock (1968–69), Michael Tippetts The Knot Garden (1965–70); Leonard Bernsteins Mass (Bernstein) (1971) and Slava! (1977); Louis Andriessens De Staat (1972–76); Helmut Lachenmanns Fassade, für grosses Orchester (1973, rev. 1987), Valery Gavrilin Anyuta (1982), Steve Reichs Electric Counterpoint (1987), Arvo Pärts Miserere (1989/92), György Kurtágs Grabstein für Stephan (1989), and countless works composed for the quintet of Ástor Piazzolla. Alfred Schnittke also used electric guitar in several works, like the "Requiem", "Concerto Grosso N°2" and "Symphony N°1".


Output: How many years did Louis Andriessens De Staat  use classical guitar?
