Be careful with this, especially if the subject and the verb or pronoun are separated by long change clauses. One of the above questions exploits this particular trap. 2) Split #1: the theme, “not a serious mathematician,” is unique. Thus, it requires a singular verb, “was.” Decisions (A) – (B) – (D) make the mistake of using “were” so they are wrong. While this choice of answer corrects the initial error of the subject`s adverb chord, by changing the plural verb dismissed with the singular verb dismisses, a new one is created. The singular theme of theatrical production does not agree with the plural verb. We can talk about “no students,” “a few students,” “most students,” “every student,” “every student,” or “all students.” It`s pretty easy to find – those with “students” are unique, and those with students are plural. This becomes more difficult when a sentence or amending clause intervenes (“no student, not even… “any student, including … “), but of course, if the names in the modifier are singular or if the plural does not affect the verb – the verb must correspond in number to the subject and only to the subject. One of the most common tricks that testers play on us when correcting GMAT phrases is that we lack a missing match between a subject and his verb.
This may seem so fundamental to any language that we could hardly miss it. In many cases, this is true. For example, it is quite easy to realize that it should be “the book” or “the books are”. However, one of the testers` tools is to place the subject away from the verb to confuse us. We start with the first of the two structures – the Y-Thema X. Let`s take the following example: Now we can see much more clearly that the singular subject does not correspond to the plural verb. The right singular verb for this phrase would be “is,” not “being.” Split #4: verb time. In choice (E), the verbs “had had” and “that was giving” are not correct for this context.
This is another problem of selecting responses (E). The correct answer is the only one where all verbs correspond in number with their objects and in the present according to the structure of the sentence. The agreement between thematic verb may seem very simple, but it will certainly be tested for corrections of GMAT sentences. You can apply many of the same considerations as pronoun-antecedent agreement for these issues.
