I don't mean to challenge the authority, but I think choice C is better than choice B. Here are some of my thoughts on Q.19. 1. "who was reported to have drunk twenty-five cups of tea at one sitting." modifies Samuel Johnson. To parallel with "was reported to have drunk", "did not seem to have bothered" seems better. 2. Samuel Johnson died even before Balzac was born. Thus "did not seem to have bothered" correctly stated that the action of bother happened before the action seem, which is in past tense as drank ... and died... in the first part of the sentence. 19.Balzac drank more than fifty cups of coffee a day and died of caffeine poisoning; furthermore, caffeine did not seem to bother Samuel Johnson, the great writer and lexicographer, who was reported to have drunk twenty-five cups of tea at one sitting. (A) furthermore, caffeine did not seem to bother (B) however, caffeine did not seem to bother (C) however, caffeine did not seem to have bothered (D) furthermore, caffeine did not seem to have bothered (E) in addition, caffeine did not seem to bother |
