Read the following article and select the best answer. Article: After sunset on our last day at the farm I walked out into the desert. In this, the first pleasant moment for a walk after long hot hours, I thought I was the only thing out of doors. Suddenly I stopped. Before me a rattlesnake lay fixed, its head not yet drawn back to strike but only turned a little to watch what I would do. Many snakes will run away at the sight of a man but this rattlesnake felt no necessity to get out of any-body's way. He held his ground in calm watch-fullness waiting for me to show my intentions. My first aim was to take no notice of him; I had never killed an animal if I was not forced to kill. But I remembered that there were children, dogs and horses at the farm as well as men and women with thin clothes on; my duty was to kill the snake. I went back to the farm and returned with a stick. The rattlesnake had not moved; he lay like a wire but more quickly than I could stride he shot into a bush and set up his rattling, warning me by this that I had made an unreasonable attack and attempted to take his life and that if I insisted he would have no choice but to take mine if he could. For a moment I listened to this terrifying sound and then I struck into the bush with my stick and, chop-ping about, dragged him out of the bush with his back broken. He struck once more at the stick but a moment later his neck was broken and he was soon dead although when I picked him up by the tail his mouth opened, proving that a dead snake may still bite. There was blood in his mouth and poison was dropping; it was not only a dis-gusting sight but a pitiful one too. I dropped the body into a green bush and, as I did so, I saw him in my imagination, crawling over the sands as he might have done if I had let him go. Question: The author had to kill the rattlesnake because_. - it stood in his way - it attempted to take his life - it presented a disgusting sight - its presence was a danger to the people and animals at the farm
its presence was a danger to the people and animals at the farm

Article: Over three million people will do their Christmas shopping entirely online this year without once visiting an actual shop, a poll has found. Overcrowding and long queues in shops are forcing people away from the high street as the hassle of Christmas shopping becomes too much. The number of people turning their backs on the high street is almost one million higher than it was last year, according to the poll by YouGov. Last Christmas 2.4 million shoppers did not do any of their shopping in actual shops. The figure this year is predicted to be around 3.4 million, equal to around 7 percent of the adult population. Over a third of people said that the main turn-off about shopping on the high street is 0ver-crow-ding. Meanwhile almost a quarter said that long queues at the cheek-out are the worst thing about it. Of the 2.065 people pored, even those who are stir taking to the shops plan to spend less time in them this Christmas. Around 31 percent of shoppers who plan to spend at least some time on the high street will spend less than half of their shopping time in actual shops, using the rest of the time to shop remotely via the internet. This compares to 28 percent of people last year. Meanwhile the proportion of people spending over half of their shopping time in high street shops has dropped from 41 percent last year to 39 percent this year. Just 2 percent of people said that they are looking forward to dealing wi.th store staff this festival season. Guy Boxall, senior product marketing manager at Casio Business Solutions Division, which commissioned the research from YouGov, said that despite the fall in people visiting the high street,humans are "social creatures" who actually like spending time together.

(Q).
Read the following article and select the best answer. Article: Sunday is more like Monday than it used to be. Places of business that used to keep daytime "business hours" are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant . A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear. The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used to keep the schools open in all seasons except summer; in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more "flexible," is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other? These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the "law of time" even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years--but unless we meet the truant officer , we may well think that we should go to school due to social custom and parents' demand rather than to the law. As adults we are familiar with "extra pay for overtime working," but less familiar with the fact that what constitutes "overtime" is a matter of legal definition. When we turn the clock forward to start daylight-saving time, have we ever thought to ourselves: "Here is the law in action"? As we shall see, there is a lot of law that has great influence on how we organize and use time: compulsory education law, overtime law, and daylight-saving law -- as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess. Question: According to the passage, most children tend to believe that they go to school because they _ . - need to acquire knowledge - have to obey their parents - need to find companions - have to observe the law
(A).
