SAT Reading & Writing: Subject-Verb Agreement with Intervening Phrases

41+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    The SAT aggressively tests subject-verb agreement by placing long, confusing phrases between the actual subject and its verb.

  • 2

    These intervening phrases are often prepositional phrases ("of the studies", "in the lab") or nonessential clauses ("who was recently promoted").

  • 3

    STRATEGY: Cross out or bracket off the intervening phrase to clearly see the core subject and verb.

  • 4

    Example: "The cache of ancient coins, discovered by historians last year, WERE sold." (Incorrect. Cross out the middle; "The cache... were sold" is wrong. It should be "was").

  • 5

    Modifiers do not change the number of the subject.

Common mistakes
  • Matching the verb to the noun immediately preceding it (which is often part of a prepositional phrase) instead of the true subject.
