Two of the questions seemed to me to have plausibly false presuppositions. It seems to me that there probably is no such thing as general intelligence, which makes it hard to say whether or not IQ tests are a good measure of it. And the third to last question presupposes that there are some predictable trends in the stock market - as far as I know, this is pretty much false, though there are plenty of irrationalities in the stock market that are driven by features of human psychology that make these prices tend not to track the value of the stock.

Also, I wasn't sure what to say for the chimpanzee question.
