Question

Quizplus · Accepted Answer

A subject must agree with its verb in number. This means both need to be singular or both need to be plural. The subject in this sentence (the procedure) is singular so we need a singular verb (is).
The trap here is that the subject (the procedure) is separated from the verb by a plural noun (lives). To avoid this trap, simply find the subject and the verb and make sure they agree. Ignore everything else.
Most doctors agree that the procedure, which could save up to 10,000 lives, is very risky.
