SAT Reading and Writing tutoring: find the subject before choosing the verb
In an agreement question, the noun nearest the verb is not necessarily its subject. A sentence may place a plural noun inside a phrase between a singular subject and its verb. Reading the underlying structure can resolve the choice more reliably than choosing what sounds familiar.
Agreement is part of Standard English Conventions. It is distinct from Expression of Ideas, which covers transitions and rhetorical synthesis.
Original teaching exercise
The collection of letters, along with two maps, ______ currently stored in the archive’s climate-controlled room.
Which choice completes the sentence in Standard English?
- are
- is
- were
- have been
Answer: B, “is”. The subject is the singular noun “collection”. “Of letters” describes the collection, and “along with two maps” adds information. Neither makes the subject plural.
Reveal the sentence’s structure
Temporarily set aside the descriptive phrases: “The collection ______ currently stored.” The singular subject takes “is”. Then restore the full sentence to make sure the meaning and grammar still work.
A and C use plural verb forms. D uses “have”, also incompatible with the singular subject here. The fact that the collection contains multiple letters does not change the grammatical number of “collection”.
Notice when the subject really changes
Compare a different sentence: “The letters and the maps are stored in the archive.” Here “letters and maps” forms a plural subject joined by “and”. The correct verb changes because the sentence’s structure changes.
Do not delete phrases mechanically in every question. Identify their role first. A phrase may contain information essential to a question about meaning even when it is not the subject controlling agreement.
Use the mistake to choose practice
If you chose “are” because “maps” was closest, write that reason in your review. Then try fresh agreement questions with different intervening phrases. If you did not know how to identify a subject, work on that skill before adding a strict timer.
Use official practice to see how conventions questions fit the full section. An online SAT Reading and Writing lesson can help you explain the grammatical relationship and check it in a new sentence.
