Teacher: In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
Teacher: Now, understand the problem? If you are still confused, see the following example:
This list contains the top 25 accounts with the most followers on the social photo-sharing platform Instagram. As of May 2018, the most followed user is Instagram's own account, with over 235 million followers. Selena Gomez is the most followed individual, with over 137 million followers. Ten accounts have exceeded 100 million followers on the site.
Solution: who has the maximum number of followers on instagram
Reason: The answer is talking about the Instagram accounts that have the most followers. The question asking about the maximum number of followers. So this is a good example.

Now, solve this instance: In the United States, the President can issue an executive order for the flag of the United States to be flown at half-staff upon the death of principal figures of the United States government and others, as a mark of respect to their memory. When such an order is issued, all government buildings, offices, public schools, and military bases are to fly their flags at half-staff. Under federal law (4 U.S.C. 7 (f)), the flags of states, cities, localities, and pennants of societies, shall never be placed above the flag of the United States; thus, all other flags also fly at half-staff when the U.S. flag has been ordered to fly at half-staff. There is no penalty for failure to comply with the above law as to enforce such a penalty would violate the First Amendment.
Student:
