Q: Article: I am in my father's house in Connecticut, sitting at a crowded table with my brother, my two sisiters and all our partners, talking about a tree. "He doesn't want it cut down." My sister says when my father has gone to bed and none of us speaks of the tree in his presence. "He says he usef to climb it when he was a boy." When I was last here, a year and a half ago, for my father's 90th birthday, Hurricane Irene drove seawater into the roads. The large tree that hangs over the houses swayed alarmingly, but it stayed up. Last October, Hurricane Sandy acused a great deal of damage. Six months on, many of the surrounding houses are on sale, but the tree that hangs over the house still stands. "That tree," my brother says, "has survived the two worst storms of the last 100 years." Though my brother thinks highly of the amazing staying power of the tree, my sister says that the tree should never have been planted: it stops light from reaching the house. My other sister's partner says that all trees fall down eventually. There is plenty of evidence for what he says: throughout the neighborhood, the ramains of similarly sized trees lie on their sides, with their roots in the air. During this discussion, I offer to pay a quarter of whatever is required to remove the tree. "A guy I talked to," my brother says, "told me it could cost us$10,000." As night wears on, the discussion becomes increaslingly meaningless. There is no point in reaching any kind of agreement, since the decision is not for us to make. It's my father's tree, and he has refused to cut down the only thing in the neighborhood older than him.
Question: When does the discussion take place?
Options: (A) After lunch (B) After supper (C) At the weekend (D) Before their father's 90th birthday

A: B

Q: Article: All things change except barbers, the ways of barbers, and the surroundings of barbers. These never change. What one experiences in a barber's shop the first time he enters one is what he always experiences in barbers' shops afterward till the end of his days. I got shaved this morning as usual. A man approached the door from Jones Street as I approached it from Main--a thing that always happens. I hurried up, but it was of no use; he entered the door one little step ahead of me, and I followed in and saw him take the only empty chair, the one headed by the best barber. It always happens so. I sat down, hoping that I might sit in the chair belonging to the better of the remaining two barbers, for he was a bit ahead. I watched the probabilities with strong interest. When I saw that No. 2 was gaining on No. 1, my interest grew to solicitude . When No. 1 was gradually losing the race, my solicitude rose to anxiety. When No. 1 caught up again, and both were about to finish and say "Next!" first, my very breath stood still with the _ . But when I saw that he had lost the race by a single instant, I rose angrily and quitted the shop, to keep from falling into the hands of No. 2; for I have none of that firmness that enables a man to look calmly into the eyes of a waiting barber and tell him he will wait for his fellow-barber's chair. I stayed out fifteen minutes, and then went back, hoping for better luck. Unfortunately, all the chairs were occupied now, and four men sat waiting, silent, and looking bored, as men always do who are waiting their turn in a barber's shop. I sat down and waited. At last my turn came. A voice said "Next!" and I give in to No. 2, of course. It always happens so. I smiled and said that I was in a hurry, and it affected him as strongly as if he had never heard it. He explored my hair with his claws and suggested that it needed trimming . I said I did not want it trimmed. He explored again and said it was pretty long for the present style. I said I had had it cut only a week before. He stopped for a moment, and then asked "who cut it?" I stared at him from the mirror and replied "You did!". Then a dog-fight attracted his attention, and he ran to the window and stayed and watched it...
Question: The author left the barber's shop mainly because _ .
Options: (A) he would like to wait for "No. 1" outside (B) he would rather be served by the best barber (C) he lacked the courage to tell "No. 2" his intention (D) he was angry at the slow speed of "No. 1"

A: C

Q: Article: FDA proposed the most sweeping food safety rules in decades, requiring farmers and food companies to be more cautious in the wake of deadly outbreaks in peanuts, cantaloupe ,and leafy greens. The long-overdue regulations are aimed at reducing the estimated 3,000 deaths a year from foodbome illness. Just since last summer, outbreaks of listeria in cheese and salmonella in peanut butter, cantaloupe and mangoes have been linked to more than 400 illnesses and as many as seven deaths, according to the Centers for Disease Control. The actual number of those sickened is likely much higher. The FDA's proposed rules would require farmers to take new precautions against contamination ,to include making sure workers5 hands are washed, irrigation water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show _ are keeping their operations clean. Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in some of the large-scale outbreaks that have hit the country in recent years. In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives ,for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at the Colorado farm where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses ,inspectors found samples of salmonella throughout a New Mexico peanut processing plant and multiple obvious safety problems ,such as birds flying over uncovered trucks of peanuts and employees not washing their hands. Under the new rules, companies would have to lay out plans for preventing those sorts of problems and how they would correct them. "The rules go very directly to preventing the types of outbreaks we have seen/,said Michael Taylor, FDA's deputy commissioner for foods.
Question: The main task of FDA is probably _
Options: (A) to protect and promote the public health (B) to help those sickened recover (C) to research on food safety measures (D) to deal with water pollution

A:
A
