This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Question: Passage: Many pesticides can be grouped into chemical families. Prominent insecticide families include organochlorines, organophosphates, and carbamates. Organochlorine hydrocarbons (e.g., DDT) could be separated into dichlorodiphenylethanes, cyclodiene compounds, and other related compounds. They operate by disrupting the sodium/potassium balance of the nerve fiber, forcing the nerve to transmit continuously. Their toxicities vary greatly, but they have been phased out because of their persistence and potential to bioaccumulate.:239–240 Organophosphate and carbamates largely replaced organochlorines. Both operate through inhibiting the enzyme acetylcholinesterase, allowing acetylcholine to transfer nerve impulses indefinitely and causing a variety of symptoms such as weakness or paralysis. Organophosphates are quite toxic to vertebrates, and have in some cases been replaced by less toxic carbamates.:136–137 Thiocarbamate and dithiocarbamates are subclasses of carbamates. Prominent families of herbicides include phenoxy and benzoic acid herbicides (e.g. 2,4-D), triazines (e.g., atrazine), ureas (e.g., diuron), and Chloroacetanilides (e.g., alachlor). Phenoxy compounds tend to selectively kill broad-leaf weeds rather than grasses. The phenoxy and benzoic acid herbicides function similar to plant growth hormones, and grow cells without normal cell division, crushing the plant's nutrient transport system.:300 Triazines interfere with photosynthesis.:335 Many commonly used pesticides are not included in these families, including glyphosate.

Answer: What did glyphosate take the place of?


Question: Passage: Spielberg won the Academy Award for Best Director for Schindler's List (1993) and Saving Private Ryan (1998). Three of Spielberg's films—Jaws (1975), E.T. the Extra-Terrestrial (1982), and Jurassic Park (1993)—achieved box office records, originated and came to epitomize the blockbuster film. The unadjusted gross of all Spielberg-directed films exceeds $9 billion worldwide, making him the highest-grossing director in history. His personal net worth is estimated to be more than $3 billion. He has been associated with composer John Williams since 1974, who composed music for all save five of Spielberg's feature films.

Answer: How much have all Spielberg-directed films combined earned in adjusted gross?


Question: Passage: Until 18 December 2010, Eton College was an exempt charity under English law (Charities Act 1993, Schedule 2). Under the provisions of the Charities Act 2006, it is now an excepted charity, and fully registered with the Charities Commission, and is now one of the 100 largest charities in the UK. As a charity, it benefits from substantial tax breaks. It was calculated by the late David Jewell, former Master of Haileybury, that in 1992 such tax breaks saved the School about £1,945 per pupil per year, although he had no direct connection with the School. This subsidy has declined since the 2001 abolition by the Labour Government of state-funded scholarships (formerly known as "assisted places") to independent schools. However, no child attended Eton on this scheme, meaning that the actual level of state assistance to the School has always been lower. Eton's retiring Head Master, Tony Little, has claimed that the benefits that Eton provides to the local community free of charge (use of its facilities, etc.) have a higher value than the tax breaks it receives as a result of its charitable status. The fee for the academic year 2010–2011 was £29,862 (approximately US$48,600 or €35,100 as of March 2011), although the sum is considerably lower for those pupils on bursaries and scholarships.

Answer:
What is the largest charity in the UK?
