Q: Read the article and select the best answer. Article: The world produces about 4 billion metric tons of food a year but 1.2 to 2 billion tons is not eaten, the study by the London-based Institution of Mechanical Engineers said. It is instead thrown away. Experts say food is wasted in both rich and poor countries, but for different reasons. Elliot Woolley teaches sustainable manufacturing at Loughborough University in Britain. He spoke at the Global Conference on Sustainable Manufacturing, which was held earlier this month in Vietnam. Mr. Woolley said in poor countries, food is usually lost while it is still in the field or during storage and transportation. He said that is because food producers there are inefficient. These businesses are unable to operate effectively without wasting materials, time or energy. But he added that once food is sold in developing countries, people usually eat everything they buy. However, people in developed countries throw away as much as half of the food they purchase. In the US, big contributors to waste include supersized portions that customers simply can't manage, and"eat as much as you want"offers in restaurants. In the UK, over-conservative sell-by dates on labels and two-for-one offers of perishable items are key factors, encouraging consumers to buy too much food to start with and to throw away items that have reached their sell-by date, but which are still edible. And efficient farming methods, transport and storage mean that most of the wastage occurs through retail and customer behavior. The British researcher called this custom"adisgrace". Elliot Woolley has created a smartphone app that he says shows users what food they have bought and when the food is about to become unsafe to eat. It also gives information on how people can combine the foods they have to make a meal. The software program is called"Pantry App". Mr. Woolley said that people who used the app reduced the amount of food they wasted by a third. But this result came from a limited experiment -- users only followed their food use for a week. Jeremy... Question: According to Elliot Woolley, the best way to stop wasting food in poor countries is probably . Options: A: making people realize the bad effects of wasting food B: increasing the production and quality of grain C: limiting the transporting and storing of food D: improving their agricultural techniques
A: D

Q: Read the article and select the best answer. Article: University is generally regarded as one of the most important times in a person's life, yet the function of this institution continues to arouse debate. Many believe that arts subjects are too easy, that practical skills are more useful and that a chosen subject for study should be clearly linked to a career. However, this view is far too simplistic. Arts subjects are very difficult. They can prepare students for any number of careers as well as allowing the student to take time to make a decision. The function of the modern university is to cater to different types of student. Arts subjects are not easy. For example, a degree in Literature is not an easy option. No question in a Literature class has a single, simple answer. Debate is conducted in a spirit of openness, texts are very closely analyzed and skills in close reading are developed. Literature is about language, our primary means of communication. Arts subjects require the same concentrated study as any other subject. Arts subjects can prepare students for any number of careers. A degree in an arts subject teaches skills in well organized debates and defence of a position through the provision of evidence. These are applicable to many types of career. Law, for example. The point is that an undergraduate degree in any Arts subject trains the student in analysis and structure. Therefore, Arts graduates can pursue any number of careers. Arts subjects allow the student to take time to choose a career. Love of the subject for its own sake may well be the initial motivation for the Arts undergraduate but because the subject they have chosen is not so clearly linked to a career they have time to reflect, making a decision only when they are absolutely certain. Students who pursue Arts subjects therefore have the leisure to make a carefully considered choice. In conclusion, it is clear that Arts subjects are not a waste of time. They are flexible when it comes to relating them to a career and they allow the student to discover an appropriate career path.... Question: What does the author imply about universities' attitude to students? Options: A: They need to be more understanding of students' needs. B: They need to keep out arts students. C: They need to link courses to careers. D: They need to offer more arts courses.
A: A

Q: Read the article and select the best answer. Article: Any mistake made in the printing of a stamp raises its value to stamp collectors.A mistake on a two-penny stamp has made it worth a million and a half times its face value. Do you think it impossible? Well,it is true.And this is how it happened. The mistake was made more than a hundred years ago in the former British colony of Mauritius,a small island in the Indian Ocean. In l847 all order for stamps was sent to London Mauritius was about to become the fourth country in the world to put out stamps. Before the order was filled and the stamps arrived from England,a big dance was planned by the commander-in-chief of all the armed forces on the island.The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius.Stamps were badly needed to post the letters.Therefore,an islander,who was a good printer,was told to copy the pattern of the stamps.He carelessly put the words "Post Office" instead of "Post Paid", two words seen on stamps at that time,on the several hundred that he printed. Today, there are only twenty-six of these misprinted stamps left-fourteen One-penny Reds and twelve Two-penny Blues, Because there are so few Two-penny Blues and because of their age, collectors have paid as much as$16,800 for one of them. Question: Mauritius printed some stamps too because _ Options: A: London stamps were not well printed B: London would not print them C: Invitations to fl big dance had to be posted quickly D: Mauritius had a very good printer
A: C
