Choose the correct pronoun to go in the gap.
Someone is the antecedent and is always treated as singular so it takes the singular pronoun. As no gender is known, we use he or she.
The antecedent is neither (not boys), and neither is always singular, so it has a singular pronoun. It is his (not his or her) because it is referring to males only.
Each is the antecedent and this is always singular, so it takes a singular pronoun. We use his or her as male or female is not specified.
Several is always plural so we can use the general plural pronoun.
Anybody is always singular so has a singular pronoun. It’s not him or her as these are used as the object. So it must be he or she.
Some (like all, most, a lot, and none) can be singular or plural depending on the noun in the prepositional phrase (of the children). In this case children is plural so the pronoun is plural. It’s also the possessive pronoun i.e. the children’s mothers.
In this case the noun is singular (roof) so the pronoun is singular.
Both is always plural.
None can be singular or plural, depending on the noun in the prepositional phrase (of the drivers). As it is plural (drivers), the pronoun is the plural (possessive).
One is the subject and is singular. And its in relation to a male (uncles) so it is his.
