B Krumpers - plural -> verb = travel, since it's referring to more than one of them performing that action. Won't be D because the noun 'crowd' is singular even though it refers to multiple persons.
b. Krumpers from around the country travel to Los Angeles each year to display their talent and raise money for inner-city youth.
A plural verb agrees with a plural subject. In B, the subject is Krumpers. The /s/ at the end of Krumpers tells us there is more than one so it is plural. The verb that agrees with Krumpers is travel, so travel must be a plural verb. In A the subject is Tommy - he is singular. In C the subject is Lil' C or Miss Prissy. Since it's one or the other not both, the verb must be singular. In D the subject crowd is also singular because a crowd is one group even though it is made up of many people. Only singular verbs agree with singular subjects so none of these other options have a plural verb.
This paragraph lacks sentence variety because the writer, started sentence after sentence the <em>same way</em>. didn't include structure with proper legth or that provides emphasis. <em>Prepositional phrase, adverbial clause, adverbs</em> (absolutely; naturally) or some<em> connective</em> (therefore; and; besides etc) are great help to <em>avoid monotony.</em>
