Answer 1

answer a) is one data answer, but if you asked 100 people, you would likely get 40 answers different
answer b) the simple answer is at stadiums, but if you want locations, you can get many answers.
answer c) If you asked 100 folks, you would get 100 different answers.
answer d) again, 100 folks will give 100 different answers.

All are ripe for statistical analysis: Is this a trick question?
