"Almost all of them could be selected, but the correct will be what the examiner has in his mind. These are not multiple choice questions (MCQs) rather best choice questions (BCQs)"

you are absolutely right I was thinking the same that all these meanings are inter-connected, more or less they seem to be same but one has to pick the best amongst those. Thanks for making it Aariz. Please help us with the idioms and adjectives too.
