Explanation:

The model sentence uses a structure with a past perfect tense and a contrastive element. We need to arrange the given phrases to match that structure. First, introduce "Mark's sister" and her previous state ("had seemed a little testy before"), then add the contrast "but only at this moment" and the resulting clarity ("did the reason become clear to him").

Answer:

Mark's sister had seemed a little testy before, but only at this moment did the reason become clear to him.
