Concept:The subject of a clause must agree in number with its verb. A singular subject requires a singular verb form.Explanation:The sentence has three labelled parts. Part (a) introduces the main clause. The error lies in part (b). The subject of the clause beginning with "that" is "the attention". This subject is singular. The verb used in part (b) is "give", which is a plural verb. This does not agree with the singular subject. The correct verb should be "gives" to match the singular subject. No errors exist in parts (a) or (c). Part (c) "that makes" correctly agrees with its subject "it". Therefore, the sentence should be corrected by changing "give" to "gives" in part (b).Answer:(b)
