Like really. Since when do polls such as this only offer "one", "none" and "all"? Should this poll not have checkboxes so that we can vote on multiple answers? If that were the case, I'd just vote for "All of the above" and "No correct choice". That's just as confusing as saying "All of the above", when the option above it is "None of the above". So "All of the above" includes "None of the above". DO they just cancel each other out, leaving us with "One correct choice, One correct choice, More than one correct choice, and No correct choice"? And if you select "All of the above" or "None of the above", does that description include the last option, "Such silly choices that I am not voting on it"? Because that option is not above those ones.... And finally, something to equate this poll to:

Which mathematical equation equals 4?
A) 2 + 2
B) 2 + 2
C) 3 + 1
D) No correct choice (Mathematically impossible)
E) None of the above
F) All of the above (A, B, C, D, E)
G) What a stupid question
Analysis:
'A' is correct
'B' is correct
'C' is correct
'D' is incorrect, since 'A', 'B', 'C' are correct
'E' is incorrect, since 'A', 'B', 'C' are correct
'F' is incorrect, since 'D' and 'E' are incorrect
'G' could theoretically be correct, but it's a
stupid answer to a stupid question, so we'll
say it's incorrect
So... 'A', 'B' and 'C' can be said to be correct.
But 'A' nor 'B' can be correct because they are the
same and both say there is only one answer, which is
incorrect. Therefore, 'C' MUST be the correct answer!!
Correct answer to this question: C
Therefore, correct answer to poll:
*** More than one correct choice ***
