Underlined nouns in the Written Expression section may be incorrect because they are plural but should be singular, or because they are singular but should be plural. Sometimes it is clear that a singular subject is incorrectly used because the verb is plural, or that a plural noun is used incorrectly because the verb is singular. In this type of item, the verb will not be underlined, because this is not a verb error. Sometimes it is obvious that a plural or singular noun is needed because of the determiners that precede the noun. Certain determiners are used only before singular nouns while other determiners are used only before plural nouns.
