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.

Example Input: Passage: While no other Timely character would achieve the success of these "big three", some notable heroes—many of which continue to appear in modern-day retcon appearances and flashbacks—include the Whizzer, Miss America, the Destroyer, the original Vision, and the Angel. Timely also published one of humor cartoonist Basil Wolverton's best-known features, "Powerhouse Pepper", as well as a line of children's funny-animal comics featuring popular characters like Super Rabbit and the duo Ziggy Pig and Silly Seal.
Example Output: Which characters matched the success of the big three?

Example Input: Passage: Television money had also become much more important; the Football League received £6.3 million for a two-year agreement in 1986, but when that deal was renewed in 1988, the price rose to £44 million over four years. The 1988 negotiations were the first signs of a breakaway league; ten clubs threatened to leave and form a "super league", but were eventually persuaded to stay. As stadiums improved and match attendance and revenues rose, the country's top teams again considered leaving the Football League in order to capitalise on the growing influx of money being pumped into the sport.
Example Output: How much was the deal worth when it was renewed in 1986?

Example Input: Passage: There is some controversy surrounding the effect of dietary fat on the development of cardiovascular disease. People are often advised to keep a diet where less than 30% of the energy intake derives from fat, a diet that contains less than 7% of the energy intake in the form of saturated fat, and a diet that contains less than 300 mg/day of cholesterol. Replacing saturated with mono- polyunsaturated fat is also recommended, as the consumption of polyunsaturated fat instead of saturated fat may decrease coronary heart disease. Olive oil, rapeseed oil and related products are to be used instead of saturated fat.
Example Output:
How many mg of fat is suggested for a healthy person's diet?
