This sentence refers to the individual efforts of each crew member. The Gregg Reference Manual provides excellent explanations of subject-verb correspondence (section 10:1001). Each verb must correspond to its subject in number (singular or plural). Subject-verb disagreement is one of the most frequently tested errors on the SAT. If you are a native English speaker, the best way to look for disagreements between subject and verb is to find the subject and verb (ignore all intermediate words) and say them together. When they write, you cut your sentences to play the Whokicked who? Exercise. Look at the subject-verb-object core (Who hit whom?) and see if it is clear and powerful the Although normally the subject comes before the verb, but inverted sentences have the subject according to the verb. For example, sentences that begin There is . or there are. Are reversed. To check the subject-verb agreement in these sentences, “do not revert them” first.
