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.

Input: Consider Input: Passage: Unlike the Baroque style that it replaced, which was mostly used for palaces and churches, and had little representation in the British colonies, simpler Georgian styles were widely used by the upper and middle classes. Perhaps the best remaining house is the pristine Hammond-Harwood House (1774) in Annapolis, Maryland, designed by the colonial architect William Buckland and modelled on the Villa Pisani at Montagnana, Italy as depicted in Andrea Palladio's I quattro libri dell'architettura ("Four Books of Architecture").

Output: What style was widely represented in British colonies?


Input: Consider Input: Passage: The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.

Output: When did the FDA Amendment become a law?


Input: Consider Input: Passage: On July 26, 1931, at a convention in Columbus, Ohio, Rutherford introduced the new name—Jehovah's witnesses—based on Isaiah 43:10: "Ye are my witnesses, saith Jehovah, and my servant whom I have chosen"—which was adopted by resolution. The name was chosen to distinguish his group of Bible Students from other independent groups that had severed ties with the Society, as well as symbolize the instigation of new outlooks and the promotion of fresh evangelizing methods. In 1932, Rutherford eliminated the system of locally elected elders and in 1938, introduced what he called a "theocratic" (literally, God-ruled) organizational system, under which appointments in congregations worldwide were made from the Brooklyn headquarters.


Output: In what year did Rutherford take over leadership of the Watch Tower Society?
