I'm not sure how many answers are allowed for this specific question, and I have no idea if this question may appear in an exam or in any exercise.
But first of all, I wonder if it is a good idea to use multiple choice on a question like that. Shouldn't it be allowed and encouraged to use more of one's reasoning ability and creativity to tackle the problem?
Secondly, without a specific context, I would say that all four choices are possible. |
