Which question would lead to the BEST topic for a report about why the job of the President of the United States is so important?
A) How long can a person be the president?
B) How old must a person be to run for president?
C) What experience is necessary to become president?
D) What is the biggest task the president must complete?

D probably.

Explanation:

I say D because the tasks the president does has an impact on the country. It might have something that changes the country, or something that keeps it from danger. The task is most important because you never know where our country is next without a leader to lead us with several things that need to be fixed.

I hope that was a good explanation.

d. it adversely affected american productivity
