Look at the bolded part of each sentence. Below each sentence, three possible substitutions for the `"bolded"` part are given. If one of them (a) ,(b) or (c) is better than the bolded part, indicate your response on the Answer Sheet against the corresponding letter (a),(b) or (c). If none of the substitutions improves the sentence, indicate (d) as your response on the Answer Sheet. Thus a "No improvement" response will be signified by the letter (d)
