##  [Subject-verb agreement: Advanced](/en/quiz/jeu-quiz-sva-advanced-eng)

Writing is a little like math. Let us explain! In math, we know that two sides of an equation must be equal—in a sense, they have to agree. In writing, subjects and present-tense verbs must also agree: if the subject is singular, so is the verb; if the subject is plural, so is the verb. In the following sentences, see if you can choose the verb that agrees with its subject.
