Change them to the passive voice.
In the sentences that you have written, is the active form of the verb or the passive form better? Which is more direct in its wording? Which, then, is the better form to use regularly?
Exercise 100—Number and Person
The number of the verb is decided by the number of the subject. If the subject is a singular noun, or a pronoun that stands for a singular noun, it requires a singular verb; if the subject is plural, it requires a plural verb. As a rule, there is no difference between the singular and the plural forms of the verb except in the form for the third person singular; as,
| I say | We say |
| You say | You say |
| He says | They say |
But as the third person of the verb is the one most often used, it must be carefully noted.
The following subjects of verbs are singular and require a singular verb to accompany them:
1. A collective noun that denotes a group of objects acting as one thing; as,
The crowd is scattering.
