Read the following sentences and mark the alternative that presents correct examples of if-clauses. i. she would buy the tickets for her trip if she has the money. ii. he would have bought more things at that store if he had had time. iii. if we had gone earlier, we would have found all the stores open. iv. if they have spare time, they would talk to you. v. if i were a boy, i’d turn off my phone.

The following two are correct:

III. If we had gone earlier, we would have found all the stores open.

V. If I were a boy, I’d turn off my phone.

I want to point out one thing about the fifth option.  “If/were” clauses are what are known as “contrary to fact,” and for contrary-to-fact statements, you’ll always need a plural verb regardless of whether or not the subject is plural.  For instance, “I” is singular; however, for contrary-to-fact statements (that use “if” or “wish”), in order for there to be subject-verb agreement, the verb will need to be plural regardless of the number of the subject as we see with the fifth sentence.  

a. the man as a ruler
