> "What is heaviest, gasoline or water?" It depends on the amount. Two pounds of gasoline are heavier than one pound of water. Yes, I get that they are asking about density, not mass. My point is that tests need to be carefully written. I remember once during an early online screening at a multinational they asked something like Alice went shopping in the morning and bought apples. What did she buy? A) Apples. B) Oranges. C) All of the above. D) None of the above. With the information provided, the only answer we can reject is D, because we know that she did in fact but apples. However, it is possible that she also bought oranges (and/or something else), in which case answers B and C would also be correct. We don't have enough information. Bear in mind this was a test for recently graduated software engineers, who are supposed to be trained in logic, so I spent a few seconds puzzled wondering why the question was worded so strangely. I did answer A and moved on.
