Some months have 31 days; how many have 28?
A
Correct answer
Explanation
All 12 months have at least 28 days. February has exactly 28 days (29 in leap years), while all other months have more than 28 days. This is a classic trick question - many people mistakenly answer '1' thinking only of February. But the question asks 'how many have 28?' not 'how many have ONLY 28?' - and every month contains at least 28 days.
