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.

Passage: Yale has a complicated relationship with its home city; for example, thousands of students volunteer every year in a myriad of community organizations, but city officials, who decry Yale's exemption from local property taxes, have long pressed the university to do more to help. Under President Levin, Yale has financially supported many of New Haven's efforts to reinvigorate the city. Evidence suggests that the town and gown relationships are mutually beneficial. Still, the economic power of the university increased dramatically with its financial success amid a decline in the local economy.
Why do New Haven city officials like Yale?

Passage: In cases where the criminalized behavior is pure speech, civil disobedience can consist simply of engaging in the forbidden speech. An example would be WBAI's broadcasting the track "Filthy Words" from a George Carlin comedy album, which eventually led to the 1978 Supreme Court case of FCC v. Pacifica Foundation. Threatening government officials is another classic way of expressing defiance toward the government and unwillingness to stand for its policies. For example, Joseph Haas was arrested for allegedly sending an email to the Lebanon, New Hampshire city councilors stating, "Wise up or die."
What did George Carlin send to the city council in New Hampshire?

Passage: The unproven Riemann hypothesis, dating from 1859, states that except for s = 2, 4, ..., all zeroes of the -function have real part equal to 1/2. The connection to prime numbers is that it essentially says that the primes are as regularly distributed as possible.[clarification needed] From a physical viewpoint, it roughly states that the irregularity in the distribution of primes only comes from random noise. From a mathematical viewpoint, it roughly states that the asymptotic distribution of primes (about x/log x of numbers less than x are primes, the prime number theorem) also holds for much shorter intervals of length about the square root of x (for intervals near x). This hypothesis is generally believed to be correct. In particular, the simplest assumption is that primes should have no significant irregularities without good reason.
When was the function hypothesis proposed?
