Consider the following sentence,
"Do you know if Jason ------ French before moving to France?"
Which of the following options best completes it?
b.has been studying
c.will have been studying
d.will be studying
Is it possible that the sentence refers to an event that already happened, that is, Jason already has moved to France, or it can only be used, the way it is phrased, to refer to an event that is still to happen?
How would you rephrase it in the case that Jason has already moved to France?
Explanation:To my non-native ears, at first it seemed like the question could be referring both to event that already happened, and also to an event that is still in the intent phase.
However, after reading native speakers discuss a similar question, they think that choices a. and b. sound immediately wrong, therefore ruling out the possibility that the sentence refers to something that has already happened.
What is the truth then?
