Correct Response: B. Syntax refers to the rules governing the way words are combined to form sentences in a language. B contains two syntax errors. In English, an adjective (older) should precede the noun it modifies (brother). Also, a direct object (lunch) should follow the action verb (eats) and precede any adverbial phrases (at home). A, C, and D are incorrect because the errors in these sentences do not relate to syntax. A contains spelling errors. C contains a semantic error in the choice of the quantifier much, which should only be used before an uncountable noun such as money or water. D contains incorrect morphological forms of the verbs bore and sing.
