[Q]: Article: Offering a powerful new tool against terrorism, researchers have found a way to detect lies in the liar's blushing face. The technique, described in the journal Nature, uses a thermal camera to detect the sudden shift of blood flow in the face. The system performed as a traditional polygraph , the scientists report. Pushed by technological advances and with fresh interest since Sept.11, the discovery is part of the development in the scientific study of detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new methods that might take the place of the polygraph, from brain scans, to slight changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding says, when a person tells a lie, there is a sudden change of blood to the area around the eyes. Although the change is not ordinary visible, the blood warms the skin, causing bands of color1 to appear through a camera sensitive to heat. One advantage of the camera can provide answers quickly, and doesn't require a highly trained expert to operate it or explain its results. In theory, this new technology could be used anywhere large numbers of people need to be quickly screened. But some scientists say the technology would need to be improved before it is ready for use, for it is possible that there are other reactions that cause a sudden change in blood flow in the face and there is also the danger that people will learn to fool the machine, the same way they try to fool polygraph examiners by controlling their breathing or taking drugs to relax themselves.
Question: Compared with a traditional polygraph, the new tool's progress lies in the fact that _ .
Options: (A) it is moveable (B) it is easier to operate (C) it gives correct conclusion (D) it can only be used in public places.
Asnwer: D
[A]: No

[Q]: Article: Rebecca, who is a 25-year-old woman, has a rare condition. She can remember all the events she has experienced in her life. The events are so vivid, as if they happened just moments ago. But her vivid memories often become a reality. Rebecca said, "When I relive memories, the emotions come back. So if it's something that happened when I was younger, my emotions are about what I felt then. I also re-experience pain. For example, I remember falling over and hurting my left knee when I was three. When talking about it now, I'm getting pain in my left knee." However, there are times when Rebecca's memories prove to be too overwhelming, and she has learnt relaxation and mindfulness techniques to solve. "At school, it is a _ . I'm not very quick at processing things, so there is always so much going through my mind. At night, I have to sleep with the radio on and a soft light. If it's too dark or quiet, my mind just recalls all these memories and I can't sleep," Rebecca said. In addition, Rebecca has no control over whether the memories she recalls will be positive or negative - recalling painful experiences with such vividness that she has suffered from post-traumatic stress disorder. Rebecca said, "Recently, I went back to my old school for my sister's high school graduation. Being in that building again brought all those memories flooding back. I burst into tears and had to leave." Rebecca and her mother Mrs. Barnes got in touch with the University of California in 2011. It was there that Rebecca knew she had Highly Superior Autobiographical Memory (HSAM). It's reported that Rebecca is one of just 80 people worldwide, who have HASM. "Finding out about HASM has been such a positive experience. Now, Rebecca has been more positive and able to do things independently, which has been excellent," Mrs. Barnes said.
Question: What's wrong with Rebecca?
Options: (A) She hardly sleeps well at night. (B) She usually gets hurt easily by others. (C) She can't distinguish between reality and dreams. (D) Her vivid memories lead her to experience sufferings.
Asnwer: C
[A]: No

[Q]: Article: In his 1930 essay "Economic Possibilities for Our Grandchildren ", John Keynes, a famous economist, wrote that human needs fall into two classes: absolute needs ,which are independent of what others have , and relative needs ,which make us feel superior to our fellows. He thought that although relative needs may indeed be insatiable , this is not true of absolute needs. Keynes was surely correct that only a small part of total spending is decided by the desire for superiority. He was greatly mistaken, however, in seeing this desire as the only source of insatiable demands. Decisions to spend are also driven by ideas of quality which can influence the demands for almost all goods, including even basic goods like food. When a couple goes out for an anniversary dinner, for example, the thought of feeling superior to others probably never comes to them. Their goal is to share a special meal that stands out from other meals. There are no obvious limits to the _ of demand for quality. For example, Porsche, a famous car producer, has a model which was considered perhaps the best sport car on the market Priced at over $120,000, it handles perfectly well and has great speed acceleration. But in 2004, the producer introduced some changes which made the model slightly better in handling and acceleration. People who really care about cars find these small improvements exciting. To get them, however, they must pay almost four times the price. By placing the desire to be superior to others at the heart of his description of insatiable demands, Keynes actually reduced such demands. However, the desire for higher quality has no natural limits.
Question: According to the passage, John Keynes believed that _ .
Options: (A) desire is the root of both absolute and relative needs (B) absolute needs come from our sense of superiority (C) relative needs alone lead to insatiable demands (D) absolute needs are stronger than relative needs
Asnwer: C
[A]:
Yes
