Question: Article: Every spring Beijing is choked by huge sandstorms.The sky turns a strange and frightening yellow colour as clouds of sand sweep down from the deserts of Mongolia and north-western China.Strong winds blow up the dust and cover everything in sight--in 2006,a storm dumped 330,000 tonnes of dust on Beijing in one night. The number of sandstorms has grown alarmingly over the years as the deserts have expanded.This is partly man-made and partly because of climate .Many grasslands have been overgrazed by sheep and goats,or ploughed up,leaving the soil dangerously exposed.Too much water has been taken out of rivers,and the situation is made worse by increasingly long-lasting droughts that have affected the northern half of China as the climate grows warmer and drier.The result is probably the worst loss of rich land to deserts in the world and a dust bowl of extremely large proportions.The nearest sand dunes to Beijing are now only 70 km away and drifting closer each year.At this rate,the desert will reach the city by 2040,and Beijing could become the world's first modern city to disappear under sand.To hold back the deserts,a huge programme of forest planting called the Great Green Wall has been under way for over 30 years.The barrier is planned to be 4,500 km long when completed in several decades ,but the drought is having a very bad effect on the trees and the deserts carry on growing.
Question: All the following are the reasons for the expansion of the deserts EXCEPT _ .
Options: (A) the soil of the grasslands is exposed (B) too much water in rivers has been used (C) it doesn't rain for a long time (D) the climate in northern China is colder and drier
Asnwer: D

Answer: Yes

Question: Article: Every year seals would crowd ashore in Farne Island and give birth to their pups. Between early October and early December, 1,500 seal pups will be born. Almost half of them will not make it past the first three weeks of life. "The pups have to stay out of the water for the first three weeks, when they have their white coat, which is not very waterproof," explains the warden ,who spends nine months on the Island. "But when you're born in November on a rock in the North Sea, it's a tough start to life," he said. Storms often wash young pups into the water. And occasionally, young, inexperienced mothers abandon their pups and head out to sea. "We lost 41% last year," said David Steel, the National Trust's head warden on the Farne Islands. "Mother Nature certainly keeps them in check." Despite the early challenges for every newborn seal, the population is healthily and slowly and steadily growing. There are almost 4,000 seals on a set of islands, which is named a Special Area of Conservation(SAC), meaning it is protected under EU regulations. This successful human safeguarding of the seals' habitat is huge turnaround . Just a few decades ago, the seal population was deliberately _ The animals used to be thought of as a threat to local fish stocks. During the late 1960s and 1970s, thousands of seals were shot in a cull that aimed to protect the local fishing industry. According to the National Trust, between 1962 and 1983 approximately 2,000 adult females and 3,000 pups were shot. But, as the fishing industry collapsed, it was gradually replaced by tourism. Today, several companies use fishing boats to take groups of people to visit the islands and admire the scenery, seabirds and, of course, the seals that make their homes in this bleakly beautiful place.
Question: In the first three weeks after they were born, almost half of the seal pups _ .
Options: (A) would be abandoned by their mothers (B) would be protected by the wardens (C) couldn't live independently (D) would die mostly in the sea water.
Asnwer: B

Answer: No

Question: Article: Faces that activate the same regions of the brain again and again are more likely to be remtembered. Practice makes perfect when it comes to remembering things, but exactly how that works has long been a mystery. A study published in Science recently indicates that reactivating neural patterns over and over again my store items into the memory. People find it easier to recall things if material is presented repeatedly at well-spaced intervals rather than all at once. For example, you're more likely to remember a face that your've seen on some occasions over a few days than one that you've seen once in one long period. One reason that a face linked to many different contexts -such as school, work and home- is easier to recognize than one that is associated with just one setting, such as a party, could be that there are some ways to access the memory. This idea, called the encoding variability hypothesis ,was proposed by psychologists about 40 years ago. Each different context or setting activates a clear set of brain regions; the hypothesis suggests that it is these differing neural responses that improve the memory. But neuroimaging research led by Russell Poldrack, a scientist at the University of Texas. Austin, now suggests that the opposite is true--items are better remembered when they activate the same neural patterns with each exposure. Poldrack's team measured brain activity in 24 people using functional magnetic resonance imaging. The subjects saw 120 unfamiliar faces, and each one repeated four times at varying intervals during the scan. One hour later, they were shown the faces again, mixed with 120 new ones, and asked to rate the familiarity of each. The researchers then looked at the brain responses that had been recorded when the subjects wee first shown the faces, focusing on 20 brain regions associated with visual perception and memory. Face that were later recognized evoked similar activation patterns at each repetition in nine of the regions, particularly those associated with object and face perception; faces that were later forgotten did not produce such pattern to the same extent in people's mind
