Read the paragraph.

[1] tia and jackie are partners in science class. [2] they have a big project to complete and are having trouble agreeing on an idea. [3] jackie would prefer to study geology, but tia is more interested in human biology. [4] ultimately, they decides to study fossilization.

which sentence has a subject-verb agreement error?

The answer is: Sentence 4.

Sentence 4 has a subject-verb agreement error. The subject in that sentence is plural ("they") while the verb is conjugated in the third person singular ("decides").

According to the Subject-verb agreement rule, subjects and verbs must agree with one another in number. Thus, a singular subject takes a singular verb while a plural subject takes a plural verb.

The correct version of sentence 4 is the following: "Ultimately, they decided to study fossilization." The reason behind this is that the subject is plural so the verb must also be conjugated in the plural form.

- "when these words are put together to convey a meaning it is known as a sentence. a sentence is a group of words that makes complete sense. placing of words in a sentence is very important. the second sentence is a question."
