In this case, the noun is singular (roof), so the pronoun is singular. The pronoun „he“ should be plural, because its predecessor is the plural meeting of resources. Only two options change „he“ correctly to „they“, but one of them, „because they depend on the reduction of foreign oil“, confuses cause and effect. Resources do not depend on the reduction of foreign oil. The correct answer is, „Because they can reduce our dependence on foreign oil.“ Many are always plural, so we can use the general plural pronoun. The choice of the answer „the person who has most changed the world through his charitable actions or scientific discoveries“ is right because it is the only answer choice that correctly uses „who“ and the singular pronoun „his or her“ to match the singular noun „person“. The original sentence contains an error in the concordance of noun pronouns: the plural pronoun „you“ is used to refer to „the worker“, a singular noun. We must use a singular possessive pronoun to refer to a singular noun, and our decisions in this case are „hers,“ „her,“ and „she.“ It is not used to refer to people, and while „the worker“ is not a gender name, we can say that the worker described in the sentence is a man because the possessive pronoun „to be“ in the sentences „his lost green helmet“ and „made himself happy on the way home.“ For the sentence to be correct, we must replace „theirs“ with „his“, so that the correct answer is: „Just when he finished the work for the day, the worker found his lost green helmet and got happy on the way home.“ In this sentence, the subject is „everyone“, a singular pronoun. Therefore, all pronouns that relate to „everyone“ should be singular. In the underlined part of the sentence, „prepare a plan to which they conform,“ „she“ is plural, not singular. Now that we have identified the problem, we need to figure out how to solve it. Since „everyone“ is gender-neutral, the best way to improve this sentence is to avoid the use of a sexist pronoun (meaning „he“ or „she“) and simply the use of a pronoun.
The correct answer, „prepare a plan and stick to it,“ achieves this goal and is therefore the best way to improve the sentence. In this pronoun-precursor quiz, you are tested on a few types of words that English learners find very difficult and with which they often make mistakes. Here are a few words: the precursor is not (not a boy), and no one is always singular, so he has a singular pronoun. It is to be (not to be or her) because it concerns only men. Some (like all, most, many and none) may be singular or plural, depending on the noun in the prepositional sentence (children). . . .
