Explanation:
The use of the correct form of the verb in a sentence corresponds with the structure or form of the sentence. This means that depending on the sentence structure and the verb used, the corresponding verbs given in brackets will be used.
In the givens sentences, the verbs in the brackets are changed according to how the verbs in the same sentence are used or structured. This means that if the one verb is in the past tense, then the corresponding verb will also be in the past tense, and if it is in a perfect tense, then the verb will again be in a perfect tense and so on.
Thus, the given sentences with their correct corresponding verbs are as follows-
1. If I was rich, I <em>would travel</em> around the world.
2. Zoe <em>wouldn't have gone</em> to Iceland if she’d known how expensive it was going to be.
