Which choice completes the text so that it conforms to the conventions of Standard English? The panel of experts ______ reviewing proposals submitted last month.
- A) is ✓
- B) are
- C) were
- D) have been
Why: “The panel” is a singular collective noun acting as one body, so the verb is singular; “of experts” is a prepositional phrase. “are” is plural and agrees with “experts” inside that phrase rather than with “panel.” “were” is plural for the same reason, and its past tense conflicts with review presented as currently under way. “have been” is plural present perfect, so it fails the same agreement test.
