Read the following article and select the best answer. Article: Digital technology -- email and smart phones especially--have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it, and only 35 percent say it's tolerated. Skeptical bosses will likely have their doubts reinforced by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while "working" remotely, while 35 percent have done housework,and 28 percent have cooked dinner. It is true, however, that working at home makes people much more efficient , because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush. The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker. More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who haven't worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough ability to change or be changed easily to suit a different situation to manage their time efficiently. Question: Why do some employers hesitate to allow remote working? - They are used to face-to-face communication. - They want to stick to their routine practice. - They have little trust in modem technology. - They fear losing control of their workers.
They fear losing control of their workers.

Read the following article and select the best answer. Article: Australia, the last continent, was discovered by ships belonging to some European nations in the seventeenth century. These nations were less interested in changing it into a colony than in exploring it. As in the early history of the United States, it was the English who set up the settlements in Australia. This history and the geography of these two British colonies have some other things in common as well. Australia and the United States are about the same in size, and their western lands are both not rich in soil. It was the eastern coast of Australia and American that the English first settled, and both colonies soon began to develop towards the west. However, this westward movement took place more because the English were searching for better land than because the population was increasing. Settlements of the western part of both countries developed quickly after gold was discovered in America in 1849 and in Australia two years later. Although the development of these two countries has a lot in common, there are some striking differences as well. The United States gained its independence from England by revolution while Australis won its independence without having to go to war. Australia, unlike the United States, was firstly truned into a colony by English prisoners and its economic development was in wheat growing and sheep raising. By 1922, for example, Australia had fifteen times more sheep than it had people, or almost half as many sheep as there are people today in the United States. Yet, in spite of these and other main differences, Australia and the United States have more in common with each other than either one has with most of the rest of the world. Question: Who turned Australia into a colony? - Britain. - Several European countries. - The United States of America. - None of the above.
Britain.
