But the real subject is The Pack, not the wolves. Wolves is a prepositional sentence that modifies the subject package. As the package of subjects is singular, the verb should be screaming: thus, there are three rules of conformity of important subjects that must be remembered when a group subject is used as a subject: so far we have worked with compound materials whose different parts are either singular or plural The rest of this unit of study studies the problems of conformity of the subjects that can arise from the placement of words in sentences. There are four main problems: prepositional sentences, clauses that begin with whom, this or what, sentences that begin here or there, and questions. Sometimes a subject may have a verb form, do and follow (instead of preceding it). As stated in the following sentences, this reversal of the usual order occurs for questions requiring a helping verb: the obvious conclusion is that subject-verb conformity errors should be avoided at all costs. However, almost all authors sometimes produce such errors, if you happen to produce a subject-verb match in one of your texts, although you have read and acquired all the rules mentioned here, you are certainly in good company! If majority/minority means a certain percentage, you can use either a singular verb or a plural verb: of course, none of us would ever write ”Subjects need verbs” or ”This tachograph needs new ideas.” We all know that plural subjects accept plural abdelle and singular subjects accept singular abdage. . . .
