I'm taking a test and have to guess the right answer to the question after the article. Article: A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated. Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic's ice cover. For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change. The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006. Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated. The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth's atmosphere. They say their study suggests the gases may have more of an effect than had been thought. Question: If the ice melts at the present speed, by the end of this century the ice loss in the Arctic Ocean will be _ according to newer studies. Options: A: 22.5% B: 35% C: 72% D: 100%

I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever wondered why you sometimes take an almost immediate liking to a person you have just met? We often get the first impression of a person based on the color1 of a person's skin or the manner in which he or she dressed. Meaning is conveyed not only by words or verbal languages but also by nonverbal communication systems, such as body behaviors. Nonverbal communication is important because we use the actions of others to learn about their affective emotional states .Our emotions are reflected in our posture, face, and eyes--be it fear, joy, anger, or sadness--so we can express them without ever saying a word .For this reason, most of us rely heavily on what we learn through our eyes. Nonverbal communication is significant in human interaction because it is usually responsible for the first impressions. More importantly, those first messages usually influence the perception of everything else that follows. Even how we select friends and sexual partners is grounded in first impressions with nonverbal communication. Nonverbal communication is important because it is culture-related. It is based on different beliefs, religions, values and customs in different cultures. When, where, how, and to whom people display his or her specific nonverbal behaviors is greatly affected by culture and context. Culture determines what the appropriate nonverbal behavior is. For example, feelings of friendship exist everywhere but their expression varies. It may be appropriate in some countries for man to embrace each other and for women to hold hands; in other countries these displays of affection may be shocking. Each culture has its own specific interpretation on nonverbal communication. What is acceptable in one culture may be completely unacceptable in another. One culture may determine that snapping fingers to call a waiter is acceptable; another may consider this gesture rude. Question: Which of the following statements is not True ? Options: A: Meaning can be conveyed both by words and body language. B: We can use nonverbal communication to learn about a person's emotional states. C: We often get the first impression by what a person says. D: The first impression can affect what we will do in the following.

I'm taking a test and have to guess the right answer to the question after the article. Article: Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station. Once inside,the cow is rewarded with food.As the cow eats,a robotic arm cleans and connects the animal to the milking machine.A few minutes later,milking is complete.The gate is opened,the cow is released and the next cow enters. The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day. The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked. The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests. Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still,she says the price of robotic milking systems will continue to limit their use. Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars.The second cost 150 000. Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day. Question: Besides milking cows,the robotic system also can _ . Options: A: adjust the temperature of milking stations B: judge the quality of fresh milk C: improve the appetite of cows D: keep fresh milk for two weeks
