Questions 68-73 are based on the following passage. Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous number of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career. ______ The student organizations seem to be effective in ensuring that the students observe university regulations.

Questions 56-60 are based on the following passage. On Thursday afternoon Mrs. Clarke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the Over 60s Club. She always went there on Thursday. It was a nice outing for an old woman who lived alone. At six o’clock she came home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house How Had somebody got in She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry. Had anything been taken She went from room to room, checking. Yes, some things were missing--her small radio, her spare watch, a camera. That was all, she thought; but she couldn’t be sure just yet. She was annoyed, of course, but rather glad that nothing had been thrown about. Over a cup of tea she wondered whether someone might have a key that fitted her front door--"a master key" perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements On the Thursday after that she went out at her usual time, dressed as usual, but she didn’t go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait. It was just after four o’clock when the front door bell rang. Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs Clarke raised the kettle and poured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet. That evening she reported the matter to the police. They were not too pleased, but they came and took away the wire and the skin. "It was only self-protection," she told the officer." An old woman must try to look after herself." With the help of a doctor the police found the man and recovered Mrs Clarke’s things. She has become something of a heroine at the Over 60s Club. The lock on the front door was one which ______.
Charley Foley calls into the Mater Misericordia Hospital to visit his wife. "How are you feeling" he asks, sitting at the bedside, close to Dolly who is smiling up at him, her black hair resting against the white pillows. "I’m fine," Dolly says, quietly. She looks old and tired to Charley; she is deathly pale and has black pouches under her eyes. When she slips her fingers into Charley’s he notices two ugly brown liver spots on the back of her small hand. "You look tired," Charley says. " Aren’t you sleeping" "I was a bit restless last night. " Dolly does not mention the pain: she doesn’t want to upset her husband. "Any word from Linda" she asks. "She phoned again last night. I told her you were grand. I said there was nothing to worry about. " Linda, their eldest, teaches in a university in Galway. Linda will come home for the holiday in August. Their son, Colin, and his children live in Australia. Cohn hasn’t been told that his mother is unwell. Colm’s a worrier: it’s best he’s not upset. Charley gazes dreamily across the chattering hospital ward, bright with pale afternoon sunlight. Other visitors are doing their duties, gathering around the sick, bringing flowers and fruit, offering words of hope and comfort. " Have you seen the doctor again" Charley asks his wife. "Tomorrow maybe. " "Any idea how long they’ll keep you in" Dolly turns away and coughs into a tissue, then settles back. She takes Charley’s hand again. "They’ll let me know on Monday. They have to do lots more tests. They won’t let me home until they know. I’m song to be such a bother. " Dolly’s small chest heaves under her heavy nightdress. Charley thinks of a frightened bird. Sweet Dolores Delarosa he used to call her long ago when they were courting, mocking her sorrowful eyes and the way she took everything too seriously. He can’t help wondering if she made herself sick with worry. Poor Dolly Delarosa! "Don’t let them budge you until you’re absolutely better," he says. "Are you managing all right, darling" "Grand. " Charley is eating out and staying away from the house as much as possible. He’s managing all right. The minutes pass in heated tedium. Charley is watching the visitors and glancing at the small alarm clock beside his wife’s bed. He can hear its distant ticking and still recall the irritating ring when it dragged his wife from bed at the crack of dawn and moments later her breakfast sounds clattering in the kitchen keeping him awake, reminding him that there’s a day’s work ahead and children to be schooled and fed. The kids are all grown up now. Second grandchild is imminent. Time is running out. A grey face in the shaving rein’or reminds Charley of middle age and the rot ahead. Where’s the point in having money if you can’t enjoy it Why can’t clocks take their time What’s the hurry Ah—God have mercy! Dolly Dolorosa. How different might it have been without her Dolly’s eyelids droop. Her mouth opens a fraction. She looks almost dead. Moments pass slowly. "This must be very boring for you," she says, without opening her eyes. "Not at all. It does me good to see you. " "It’s not nice having to visit anybody in hospital. It’s so depressing. " "Nonsense. " Dolly settles her dark head further back against the white pillows. Grimaces for an instant then braves a smile. "You should leave now, Charley. I think I might sleep for a while. " "Are you sure" "Positive. " Charley bounces to his feet. "I’ll come in later," he says. "Please don’t. With it being Saturday the wards will be crammed with people. Leave it till the morning. Come after Mass. " "Is that what you want" "It is, darling. " Doily opens her eyes, smiles like a child. It’s been a long time since Dolly was a child. "You look tired, darling," she says. "Aren’t you sleeping" "I was a bit restless last night. " "Try to take things easy. " Dolly squeezes her husband’s hand; presses her ringed finger against his gold wedding ring. Her fingers are light as feathers. "Off you go, darling," she says. "Try to not worry. " Charley bends and kisses Dolly’s hot forehead. "I’ll see you tomorrow," he says. Dolly’s eyes close. Her fingers slip from his. Charley walks along a polished corridor and finds the exit. Outside in the bright ear park he locates his car and sits inside. He glances around at the visitors coming and going. Nurses walk past, reminding him of butterflies. The underlined word "heaves" in Paragraph 15 probably means
