Explanation:
Conditional sentences are elucidated as the sentences that expresses a condition and the consequences associated with it. These sentences are also employed to express the hypothetical situations or factual implications as well.
The given sentences exemplify <u>'second conditional sentence' as they express two ideas simultaneously either to reflect a hypothetical situation(that is unlikely to be true) or a future situation(with a very low probability)</u>. In these sentences, the 'if' clause is written in past simple tense and the another clause uses 'would + V1' to state the another idea. Thus, the above sentences are filled as per this rule.
