a grammar test question Hi could someone help explain this question. The anwser is a, but why b is not possible？ I think the answer b can be interpreted as the action of making coffee was in progress and spanning which included the action of going home.

When John got home from work, _____. a. she made a cup of coffee b. she was making a cup of coffee c. she makes a cup of coffee d. she has made a cup of coffee Thank you

How to know to use preposition "to + V-ing" in this sentence Hello could someone explain how to know to use preposition to+Ving in this sentence. Even half a century ago, Marshall McLuhan, who came closer than most to seeing what was coming, warned, “When things come at you very fast, naturally you lose touch with yourself.” The "to seeing" I found that prep+Ving are normally used in below cases, 1. phrasal verb 2. part of noun + preposition combination ex. "addiction to" 3. part of adjective + preposition combination ex. "opposed to" However, I see it doesn't fit in those cases. How to know that in this case we have to use preposition+Ving (does the sentence have some sort of preposition marker so we know preposition should be used) Below is my understanding. Preposition phrase and infinitive phrase can function as adj In this case a preposition phrase "to seeing what was coming" acts as adj and modifies "most" (most people). But an infinitive phrase "to see…" also can act as adj. What is the different between them acting as adj ? Thks
