I'm taking a test and have to guess the right answer to the question after the article. Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner. Question: Which of the following statements is TRUE? Options: A: The dogs were not all provided with the entire face, B: According to their size, the dogs were given either upper or lower halves. C: The dogs could read even small changes that accountancy facial expressions after some training. D: The dogs couldn't read strangers facial emotions.

I'm taking a test and have to guess the right answer to the question after the article. Article: Just the mention of the TOEFL, GRE and GAMT exams brings a thought of long hours of dull paper work. But that idea is becoming increasingly out of date. As planned, computerized tests will begin next year which will bring a series of changes from test psychology to scoring techniques. From computer - equipped rooms, examinees will answer the questions on a computer. If they are sure about their choices, they can pass to the next question by pressing the entry "next". Then another question will be randomly selected from a vast test item bank and appear on the screen. After answering all the questions, examinees can choose the entry "quit" if they are not satisfied with their performance, or "score" if they want to see the result. Scores will be calculated immediately and appear on the screen. By that point, student's marks are official--there is no going back. Since they greatly shorten the painful waiting process-which used to be two or three months, computerized tests have won worldwide popularity. Besides, there will be no rushing to the registration offices( )for these exams. Computerized tests will be given every workday in an exam center with all three kinds of tests being held in the same room. All test takers need to do is to call the exam center and book their seats for a particular day. In addition it will become technically possible to apply new testing procedures. In the past,each examinee had the same set of test items despite differences in their ability. Under a computerized system, however, if the computer judges an answer is right, a question of a relatively difficult nature will follow. But if an examinee continues to give wrong answers and is judged as un-qualified by the computer system, he will be automatically _ the chance to go further in the test. Question: If an examinee is not satisfied with his performance _ . Options: A: he can admit defeat and give it up B: he can ask the computer to give some advice C: he can ask another chance within a few days D: he is allowed to do it once again

I'm taking a test and have to guess the right answer to the question after the article. Article: In the September of my gap year, I left school to take a semester-long outdoor leadership course run by the National Outdoor Leadership School (NOLS) in the region of South America called Patagonia. The concept of the course is to give students a chance to really develop both outdoor skills and life skills. The NOLS does an amazing job in designing their courses so that students get a full range of experiences from which they can learn many new things. We spent the first part of our semester obtaining our Wilderness First Responder certificates. This involved a 10-day, 80-hour, EMT taught course at the NOLS base camp in Patagonia. We learned many medical skills that all could be applied to everyday environments as well as the wilderness we were about to enter. After the first part of the semester, we set off on a 30-day sea expedition along the coast of the southern tip of Chile. During this expedition we learned a lot of useful skills for our future life. What excited me most was to see a large glacier pouring right out into the sea. It was unlike anything I had ever seen, and the satisfaction of reaching such a remote place all with my own power was amazing. The next part of our semester was another 30-day expedition traveling through the Andes mountain range of southern Chile and Argentina. Again we learned many technical outdoor skills and some great life skills, such as how to be effective leaders and how to function as a single group. The highlight of this part was being able to ice climb on a glacier using anchors and ropes that we set up ourselves. The final part of the NOLS semester was a 10-day small group expedition. This was an opportunity for us to get into small groups of 4 or 5 and put all the skills we had developed over the course. We planned our own routes, prepared our own clothes and equipment, and _ our plans without the help of instructors. It was a great sense of achievement to be out there on our own and ensure safety with our own knowledge. I really enjoyed my first experience of my...
