Struggling with subject-verb agreement errors on the Writing Section of the SAT?
Prepositional phrases and the preposition “of” might be to blame!
The subject of a verb is never in a prepositional phrase! On the SAT, the object of the preposition will usually agree with the verb, while the true subject of the sentence is in disagreement.
Erroneous sentence: The results of the medical test was negative.
The prepositional phrase makes it sound like “test” is the subject of the verb “was,” but it’s not–”test” is part of a prepositional phrase, and the subject of a verb is never in a prepositional phrase. The actual subject in this sentence is “results.”
Correction: The results of the medical test were negative.
