TASK DEFINITION: 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.
PROBLEM: Passage: Turner Classic Movies also airs regularly scheduled weekly film blocks, which are periodically preempted for special themed month-long or seasonal scheduling events, such as the "31 Days of Oscar" film series in the month preceding the Academy Awards and the month-long "Summer Under the Stars" in August; all featured programming has their own distinctive feature presentation bumper for the particular scheduled presentation. The Essentials, currently hosted by Osborne and Sally Field as of 2015[update], is a weekly film showcase airing on Saturday evenings (with a replay on the following Sunday at 6:00 p.m. Eastern Time), which spotlights a different movie and contains a special introduction and post-movie discussion.

SOLUTION: When does 15 Days of Oscar occur?

PROBLEM: Passage: Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.

SOLUTION: What is always possible to do?

PROBLEM: Passage: Morality plays emerged as a distinct dramatic form around 1400 and flourished until 1550. The most interesting morality play is The Castle of Perseverance which depicts mankind's progress from birth to death. However, the most famous morality play and perhaps best known medieval drama is Everyman. Everyman receives Death's summons, struggles to escape and finally resigns himself to necessity. Along the way, he is deserted by Kindred, Goods, and Fellowship - only Good Deeds goes with him to the grave.

SOLUTION:
What is the least famous morality play from the medieval period?
