What is your suggestion as for how to think of which preposition is more appropriate to use before "which/whom"? There are two sentences I want to merge with, united becomes one sentence. The second one becomes an identifying/a non-identifying clause which describes the main clause.
What I do, usually, I write the sentences down first or just think about them in my head, and I determine the preposition that comes after the verb/adjective in the second sentence.
So, for example, the sentence before the number 1 (see above), there is a verb "paid" and I can think of the preposition "for", because -> (pay + for + something), then I can assure myself that the correct preposition is for and put it before which. 2 steps basically.
Is there the easiest way to do this, especially for the sentences that has similar construction to number 3 and 5? In that case, I can't determine the correct prepositions because, in my view, it's unkown, meaning I don't know where I should match the preposition with. Someone told me that this is something I should learn by heart, but I believe there must be a way to learn the pattern. Hope you can help me. Thanks. Since, I have the answer key, it's not necessary to directly give me the answers. I only need to know how I should think to choose the correct prepositions.
