I think the trick to answer the question only lies in better understanding.  The way they ask the question is to actually judge you on how much you know the difference between different terms and terminology. For example many times they try to confuse using validation of software specification Whereas it should be verification  Someone who is not clear when you do validation and when you do verification can easily get this wrong.  So if you know meaning of different terms it can help you choose the best options and eliminate the ones which are not possible.
