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 some of the words: several are always plural, so we can use the general plural pronoun. Everyone is always singular and therefore has a singular pronoun. It is not him or her, because they are used as an object. It must be him or her. The precursor is neither (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. No one can be singular or plural, depending on the name of the prepositional sentence (the pilot). Since it is plural (driver), the pronoun is plural (possessive). Some (like all, most, many and none) can be singular or plural, depending on the noun in the prepositional sentence (of the children). In this case, the children are plural, so the pronoun is plural. It is also the possessive pronoun, that is, the mothers of the children.
In this case, the noun is singular (roof), so the pronoun is singular. Everyone is the precursor, and it`s always singular, so it takes a singular pronoun. We use her or her as male or female is not specified. The first is the subject and is singular. And it`s in relation to a man (uncle), so it`s being. Someone is the precursor and is always treated as a singular, so he takes the singular pronoun. As no gender is known, we use it or we use it. .
