Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects about 60,000 people in Africa a year. British and Canadian experts say drugs could attack the parasite causing the illness needs to survive. They say the drug could be ready for human medical test in about 18 months. The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system. It has similar symptoms to malaria , making it difficult to diagnose. Left untreated, it moves to the brain, resulting in mental confusion and final death The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies. Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases." He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease. The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection. The research in Dundee was _ by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada. The two drugs currently available to treat sleeping sickness both have problems. One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said. Question: We can learn from the passage that _ . Options: A: big drug companies play an important role in the research of the new drug B: people who get infected with the disease are mentally disturbed C: among 200 people infected with the disease, 5 may die because of the old drug D: Professor Paul Wyatt may be a professor at the University of York
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Deception is something that people do all the time ,and it plays an important role in military strategy. Now some researchers are trying to figure out how to get robots to do it, by looking at the behavior of squirrels and birds. At Georgia Tech, a team led by Ronald Arkin , a professor at the School of interactive Computing, studied the literature on squirrels hiding their acorns .Squirrels will hide their food m a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by running to a fake location. Ronald Arkin and his Ph. D. student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a "predator " machine by doing what ei squirrel does: showing the enemy a false location for an important resource. The team also looked at how other animals in this case,a species of bird called Arabian babbler~ drive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping wings and making noises. The babblers don't ever actually fight the animal they want to drive off; they just make enough noises and flaps around enough so that it seems that attacking a babbler isn't worth it They found that the deception works when the group reaches a certain size--essentially, when enough birds arrive to convince the enemy that it's best to back off . Davis modeled that behavior in software using a military scene and found that it worked even if the group didn't have the firepower to confront the enemy directly. The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead an enemy down a fake trail or make itself look more dangerous than it actually is. Question: What is the main idea of the passage? Options: A: Animals' behaviors are researched to be applied to the study of military robots. B: Robots, fooling tricks are applied to the study of animals'behaviors. C: Birds and squirrels are the animals that are good at deception. D: Researchers are interested m animals'military-related behaviors.
Answer: A

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Face-to-face communication involves much more than the spoken word.In fact, we often communicate our feelings to others through our body language without realizing we are doing so.We communicate through posture, gesture and facial expression.But the eyes also play an important part in this unspoken language.William Shakespeare called the eyes "a window to the soul," and you can learn to look through that window and better understand a person's body language by reading eye movement. Begin a conversation and ask a simple question.Watch carefully for eye movement during the response.If the person looks up, he or she is thinking or forming pictures.This is also a sign of a visual thinker.Looking up and to the left shows recalling a memory, while looking up and to the right could show imaginative construction or lying. If the person looks down, this could be a sign of obedience or even blame.Looking down and to the left can show a person talking to themselves.Looking down and to the right can show that they are feeling strong emotion. Looking sideways can indicate distraction or checking out a potential threat, hut a sideways glance can also show anger.In addition, eyes that look side to side often show shiftiness and lying. A glance usually indicates a desire for something.Glancing at a door could show a desire to leave the room, while a glance, at a person could indicate a desire to talk to them.A glance is also used when it is forbidden to look at something. A person who is lying to you may hold eye contact longer than normal.In addition, this person might smile with his mouth but not with his eyes.Smiling with the eyes is difficult to do if the emotion is not genuine. Rapid blinking of the eyes can occur when a person is thinking, and this can also be another sign of lying.Again, a person who is aware of this sign might overcompensate and stare. Question: The writer wrote this passage to _ . Options: A: introduce the different meanings of the body languages B: teach us how to use eyes to express ourselves C: explain the importance of body languages D: tell us how to read eye movement
Answer:
D
