SKILL 45: CHECK PRONOUN REFERENCE FOR AGREEMENT
After you have checked that the subject and object pronouns and the possessives are used correctly, you should also check each of these pronouns and possessives for agreement.
The following are examples of errors of this type that you might find on the TOEFL test:
In the first example, the singular pronoun “him” is incorrect because it refers to the plural noun “boys”. This pronoun should be replaced with the plural pronoun “them”. In the second example, the plural possessive adjective “their” is incorrect because it refers to the singular “everyone”. This adjective should be replaced with the singular “his” or “her”.
