Q: Read the following article and select the best answer. Article: Over two hundred years ago, Adam Smith introduced some ideas which brought about a world revolution.If we enjoy a high standard of living in modem society, we owe much to this Scottish economist and philosopher.If we enjoy driving in beautiful cars, wearing fashionable shoes, or flying away to distant places for exciting holidays, we should perhaps pay thanks to the man who made it all possible. What was Adam Smith's contribution? Like so many ideas which have surprising effects, his was a simple one.He watched workers practicing their craft of pi11 making.One man would heat the strip of metal, stretch it out, cut off a suitable length, shape it, cool it and finally smooth and shine it.Smith drew attention to the advantages which could be gained if these various tasks were performed by different workers.Let one be responsible for preparing the metal.Another for stretching and cutting.Another for shaping.Another for finishing.He described the technique as the Division of Labor; in this way workers repeat the same actions again and again.Smith made the world believe that specialization could solve the problem of poverty and want. What was the result? The Industrial Revolution.Productivity was greatly increased.For Britain, where the revolution started, there was a prosperity which made it the richest country in the nineteenth century.British trains and railway lines spread out like a spider's web across the world.British ships were used to carry the new goods from one comer of the world to another. The revolution is not over.It is still with us, but now it is a worldwide phenomenon .Everywhere, factories are producing large numbers of similar products, and are in continuous production.What were called mass - production lines yesterday are called robotic productions today.The pace of change is increasing.And if these techniques have brought us prosperity, they have also brought us a little misery in overcrowded towns, boring jobs and, most of all, unemployment. Question: We can learn from the text that the Industrial Revolution _ . - led to Adam Smith's idea of specialization - was finished in the nineteenth century - also has its side --effects in society - put an end to poverty in the world
A: also has its side --effects in society

Q: Read the following article and select the best answer. Article: The Vienna-based researchers showed that dogs will stop doing a simple task when not rewarded if another dog, which continues to be rewarded, is present. The experiment consisted of taking pairs of dogs and getting them to present a paw for a reward.On giving this "handshake" the dogs received a piece of food.One of the dogs was then asked to shake hands, but received no food.The other dog continued to get the food when it was asked to perform the task. The dog without the reward quickly stopped doing the task, and showed signs of anger or stress when its partner was rewarded. To make sure that the experiment was really showing the interaction between the dogs rather than just the frustration of not being rewarded, a similar experiment was conducted where the dogs performed the task without the partner.Here they continued to present the paw for much longer. Dr Frederike Range from the University of Vienna says this shows that it was the presence of the rewarded partner that was the greater influence on their behaviour. "The only difference is one gets food and the other doesn't, they are responding to being unequally rewarded." she said. The researchers say this kind of behaviour, where one animal gets frustrated with what is happening with another, has only been observed in primates before. Studies with various types of monkeys and chimpanzees show they react not only to seeing their partners receiving rewards when they are not, but also to the type of reward. The dog study also looked at whether the type of reward made a difference.Dogs were given either bread or sausage, but seemed to react equally to either.Dr Range says this may be because they have been trained. Question: What would the dogs do if they presented their paw alone? - They would go on with the performance much longer. - They would be too shy to present their paw. - They would miss their partners. - They would compare what they got with that of others.
A: They would go on with the performance much longer.

Q: Read the following article and select the best answer. Article: Apple is to open a research lab in the southern Chinese city of Shenzhen, according to Tim Cook, its chief executive, as it seeks to boost sales in the country and improve ties with the authorities. Beijing has been encouraging foreign technology companies to carry out more high-end work on the mainland as part of efforts to revitalize local industry. It will be Apple's second facility in China. It already has a new research and development facility in Beijing. The two R&D centers were "aimed at strengthening relationships with local partners and universities as we work to support talent development across the country", Apple said in a statement. A closer relationship with the Chinese authorities has been a priority following setbacks for the US technology company this year. The iPhone has been losing market share to high-end handsets made by local competitors including Huawei, Vivo and Oppo, which topped the rankings in the second quarter, while Apple languished in fifth place, according to Canalys data. Analysts said the announcement of the R&D centre was Mr. Cook's latest attempt to gain favour with Beijing, following the US group's $1billion investment in Didi Chuxing, the Chinese car-hailing company, in May. Apple has had to change its approach in China as it faces rising nationalism and high-quality local competition, according to Ge Jia, a tech blogger, who wrote yesterday: "It's time for Apple to cast aside their pride." "Their previous strategy of only selling devices to China without leaving anything behind is not working any more and they are starting their process of localisation in China through the Shenzhen lab." Question: Which of the following is true? - There is only one research facility in China. - Apple has always been in good relationship with Chinese authorities. - Huawei has ranked to No.1 in the second sales quarter. - Apple is changing its strategy in order to boost sales.
A: Apple is changing its strategy in order to boost sales.
