Originally posted by FormerlyLBFG The questions are inherently flawed, though. They make bad assumptions.
For example, the second question IN NO WAY tells you that the refrigerator you are using is the SAME ONE that you used for the giraffe.
Also, you are not given the dimensions of the refrigerator or of the giraffe to even know if it would even be possible in the first place. (And you'd probably have to kill the giraffe by cutting him into little pieces/etc). Same for the elephant.
Also, the third question assumes the elephant does not escape from the oversized refrigerator (assuming you didn't kill him by chopping him up). It in no way tells you that he does not escape.
Question four in NO WAY tells you that it is even in the same imaginary universe as any of the previous questions. Therefore, any assumptions that it is are null and void and hence so is the question. The correct answer is NOT ENOUGH INFORMATION GIVEN. Are you in the Amazon? Do you have a raft? What time of day is it? etc... again, NOT ENOUGH INFORMATION!
