3.1 Agreement, Pronouns, and Reference

Why Agreement And Reference Matter

ACT English places grammar inside short prose passages, so agreement and reference errors rarely announce themselves as isolated rule drills. A verb may sit next to a plural noun that is not its subject. A pronoun may appear after two people, two objects, or an entire clause, creating a reference problem. The official ACT English description places these skills under Conventions of Standard English, which includes grammar, usage, and mechanics; in practice, that means the test expects you to revise like an editor, not recite labels.

The high-value habit is to slow down for five seconds when a verb or pronoun is underlined. Do not ask, "What sounds natural?" first. Ask, "What word controls this form?" The answer choice that sounds smooth but attaches to the wrong noun is a classic trap.

Subject-Verb Agreement

A subject controls the number of its verb. Singular subjects take singular present-tense verbs, and plural subjects take plural present-tense verbs. The ACT often hides the subject with an intervening phrase: a prepositional phrase, a relative clause, an appositive, or a parenthetical aside.

Example: The collection of student essays reveals several regional patterns. The subject is collection, not essays, so the singular verb reveals is correct.

Use this quick filter before comparing answer choices:

Compound And Indefinite Subjects

Two subjects joined by and usually create a plural subject: The editor and the designer approve the layout. A compound idea can be singular when it names one unit, but ACT English usually tests the straightforward rule. With or and nor, the nearest subject controls the verb: Neither the posters nor the brochure has the updated date; neither the brochure nor the posters have the updated date.

Indefinite pronouns create many ACT traps. Each, every, either, neither, one, anyone, everyone, and someone are treated as singular in standard ACT-style usage. Each of the cameras has a protective case. The plural noun cameras is only inside the phrase of the cameras; it does not control the verb.

Pronoun Agreement And Case

A pronoun must agree with its antecedent, the noun it replaces. Singular antecedents need singular pronouns; plural antecedents need plural pronouns. If the sentence says, "The committee released their report," ACT English may prefer its report when the committee is acting as one body. If the passage treats individual members separately, a plural rewrite may be better: The committee members released their reports.

Case is about a pronoun's job. Subject pronouns perform actions: I, he, she, we, they, who. Object pronouns receive actions or follow prepositions: me, him, her, us, them, whom. In "The coach thanked Maya and me," the pronoun follows the verb thanked as an object, so me is correct. In "Maya and I reviewed the draft," the pronoun is part of the subject, so I is correct.

The who/whom test is useful when the sentence is tangled. Replace the word with he or him. If he fits, use who; if him fits, use whom. The student who designed the logo won the contest. The artist whom the class interviewed described the process.

Clear Reference

Agreement is not enough if the reference is unclear. ACT English rewards clarity, so a pronoun that could point to more than one noun is vulnerable. In "After Lena showed Priya the sketch, she suggested a revision," the pronoun she could mean Lena or Priya. The clean revision names the person: After Lena showed Priya the sketch, Priya suggested a revision.

Ambiguous reference also appears with this, that, which, and it. A sentence such as "The lab reduced waste by reusing containers, which impressed visitors" is usually clear because which refers to the whole preceding action. But "The lab stored samples near the containers, which were labeled incorrectly" may be unclear if both samples and containers could be labeled. The best ACT answer often replaces the pronoun with the specific noun.

Exam-Day Workflow

1. If a verb is underlined, bracket the subject and cross out interrupters.
2. If a pronoun is underlined, name the antecedent out loud in your head.
3. If two nouns could be the antecedent, prefer the answer that names the noun.
4. Check case only after deciding whether the pronoun is a subject, object, or possessive.
5. Keep the original wording only when it is grammatical and unambiguous.

Traps To Expect

The ACT likes sentences where a plural noun sits immediately before a singular verb, or a singular noun sits immediately before a plural verb. It also likes pronoun choices that sound conversational but fail formal case: "between you and I," "the guide gave Sara and I directions," or "her and Max prepared the display." For possessives, remember that its is possessive and it's means it is or it has. Possessive pronouns do not use apostrophes.

The final check is meaning. A technically grammatical answer can still be wrong if it points the reader to the wrong person, object, or idea. On ACT English, the best answer is the one an editor would leave in a polished passage: matched, concise, and clear.
