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: Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.
answer:
What does OSL stand for?


question:
Passage: Gender identity forms an important part of identity in psychology, as it dictates to a significant degree how one views oneself both as a person and in relation to other people, ideas and nature. Other aspects of identity, such as racial, religious, ethnic, occupational… etc. may also be more or less significant – or significant in some situations but not in others (Weinreich & Saunderson 2003 pp26–34). In cognitive psychology, the term "identity" refers to the capacity for self-reflection and the awareness of self.(Leary & Tangney 2003, p. 3)
answer:
What type of identity is less important in psychology?


question:
Passage: Under Walter Dill Scott's presidency from 1920 to 1939, Northwestern began construction of an integrated campus in Chicago designed by James Gamble Rogers to house the professional schools; established the Kellogg School of Management; and built several prominent buildings on the Evanston campus, Dyche Stadium (now named Ryan Field) and Deering Library among others. In 1933, a proposal to merge Northwestern with the University of Chicago was considered but rejected. Northwestern was also one of the first six universities in the country to establish a Naval Reserve Officers Training Corps (NROTC) in the 1920s. Northwestern played host to the first-ever NCAA Men's Division I Basketball Championship game in 1939 in the original Patten Gymnasium, which was later demolished and relocated farther north along with the Dearborn Observatory to make room for the Technological Institute.
answer:

What type of campus did Northwestern begin construction of during Walter Dill Scott's vice-presidency?
