As you can see, there is no perfect system. As far as questions goes, yes the question "What does 1+1 equal to?" is useless but the question "Please remove the letters X and Y from the following word: cXaYXpiXXtalYisXm" is pretty good right now. The advantage of CAPTCHAv2 is that you create the questions and answers, so unlike the randomly generated implementations which always expect a 6 to 8 letter input. CAPTCHAv2's answer can vary from a single word to a full sentence. I have created a few pages explaining CAPTCHAv2 in greater detail and how to use it as a bot trap.
