It feels like there can be more than one correct answer to the way these questions are posed [closed]

Solution 1:

No, it is not a reasonable test: there are usually many “correct” answers, not just one alone, in those examples.

This is yet another dumb guessing game where the student must pick what the instructor wants them to, not what is right. It does not uniquely reflect actual grammatical English as invariably chosen by native speakers in all possible contexts.

So the test isn’t worth diddly squat.
