Choose the most appropriate answer in the numbered 13 Options:Choose the option that best completes the gap(s).
Last Monday his father asked me, _____ .
Options:Select the option that best explains the information conveyed in the sentence.
I think she takes her guardian's support for granted?
Options:Professor Ikin emerged from the charm incident a changed man. During the preceding months when his wife had talked persistently about Dr. Okoro and his American friends he had paid little heed to her. He assumed that nagging was her way of life. Dr. Okoro did not constitute a threat to him; they were not in the same department so they could not be competing for the headship of the department. Even if they thought the same subject, Okoro could surely not deem to be a rival to him. He was an Associate Professor while Okoro had only just become a Lecturer Grade II. If he had yielded to his father’s pressure to marry early he might have produced a child as old as Dr. Okoro. Two member of the Provisional Council had had intentionally dropped broad hints that he was lined up to take over from Dr. Wilson as Vice Chancellor. He did not therefore need to any more notice of Dr. Okoro’s attitude towards him than a cow take notice of a fly perching on its back.
It was true Dr. Okoro got on well with the Americans who happened to be at the helm of the affair of Songhai. But what could they do for him? At best, in the teeth of strong opposition from all quarters, they could make him a Senior Lecturer. Even that will require the approval of the Provisional Council, and Okoro should not take for granted that half the members would not accept him as a child born today who would attain full maturity tomorrow. Professor Ikin knew what displeased the Americans about him – it was his lack of a Ph.D., but he hoped that over the years they would learn to judge a man by what he produces rather than by the degrees he has accumulated. If they did not, it was just too bad because only an earthquake could move him away from Songhai at such a crucial stage of its development.
Despite the fact that the Americans liked Dr. Okoro, he may not be made a senior lecturer because Options:The young are not listening to their elders, and perhaps they never have. But now it happens that, with many of them, the reason may be medical. The young aren’t listening because they can’t hear. Just as nagging parents have long suspected, otologists (hearing specialist) now report that youngsters are going deaf as a result of blasting their eardrums with electronically amplified rock ‘n’ roll.
The hearing specialists used to worry about loud noise as a cause of deafness only in industrial and military situations. They knew that eight hours of daily exposure, year in and year out, to the din of the proverbial boiler factory, would eventually result in permanent hearing loss. Riveters were particularly susceptible. Then they learned that the same thing happened to aviators. After the advent of jets, the hazard applied to the ground crews at airport and flight-deck personnel aboard aircrafts – hence the introduction of insulated noise absorbing plastic earmuffs.
In discotheques and rock ‘n’ roll joints, the trouble is not so much in the instrument themselves, or the close quarters. The blame goes to the electronic amplifiers. An old-fashion military ban, playing a march in Ramat Park, generated as much sound. But the sound was not amplified and was dissipated in the open air. A trombonist sitting in front of a tuba player might be a bit deaf for an hour or so after a concert, and then his hearing returns to normal. A microphone hooked up to a public address system did not appreciably increase the hearing hazard. What he did was multiple microphones and speakers, and the installation of internal microphones in such instruments as guitars and bouzoukis.
What is the difference between an old - fashioned military band on the one hand and discotheque and rock 'n' roll joints on the other? Options:In each of this question choose the option opposite in meaning to the word or phrase underlined:
The soldiers tried in their dogged defence of the city.
