Read the following article and select the best answer. Article: THE human face doesn't lie. We show sadness and happiness through our expressions. But exactly how many emotions can our face make?Scientists used to believe we had six basic facial expressions that tell others how we feel: sad, happy, surprised, fearful, angry and disgusted . But a new study shows that our faces can do more than we think. Scientists from Ohio State University found out that humans can actually make 21 different facial expressions after studying how people move their facial muscles. The scientists took pictures of 230 volunteers making faces in response to different cues .These cues included phrases like "you just got some great unexpected news", which produced a "happily surprised" reaction from volunteers. Other cues included "you smell a bad odor ", which caused "disgusted" faces. In total, around 5,000 pictures were taken of the volunteers. The scientists then studied similarities of these pictures using a computer expression database. _ helped them to define a facial expression. "That tells us that these 21 emotions are expressed in the same way by nearly everyone," said DrAleix Martinez to The Daily Telegraph. For example, to express surprise, 92 percent of volunteers widened their eyes and opened their mouth. And 99 percent raised their cheeks and smiled to show being happy. We are not always aware of our facial expressions, which can hold clues to how we really feel. So these results may have a big impact on medical treatment. If doctors were able to recognize more complex emotions, it would help doctors treat patients suffering from certain diseases. Question: How didscientists from Ohio State University find out the number of facial expressions? - They studied how people move their eyes. - They studied how people move their mouths. - They studied how people move their facial muscles. - They studied how people move their eye balls.
**Answer**

Read the following article and select the best answer. Article: Very few people enjoy exams. I don't, either. And although I tell myself not to worry about them, I always do! So I'm not surprised that my students worry about them, too, even though they usually don't need to. Because they are afraid of failing. However, since it is hard not to worry at all, we all must try not to worry too much. Why? Because worrying makes exams worse! How to do this? Ask the teacher about how to revise and about exam skills--how to work when you are in the exam. Good students don't wait until the week before an exam. They study all through the year. It is not possible to learn everything at the last minute. So don't leave it till then. If you start planning and working for each exam early and you make sure that you understand what you're studying, then, when it is over, you'll be able to say, "What a good exam that was!" Take a short rest during your time of work and revision. If your mind is tired, it won't remember well. Work at the time when you know you'll work at your best. If you're studying in the evening, don't go straight to bed afterwards. Your mind will still be "going round and round"--thinking too much. Do something else, maybe walk or get exercise. Choose something that will relax you, and make you think of other things. If you feel bad, talk to someone about your worries. But don't be too relaxed! Some stress over exams makes you work hard for them. Question: According to the passage, if you feel bad, you'd better _ . - take a short rest - tell someone about your worries - walk or get exercise - keep busy working and forget your worries
**Answer**
tell someone about your worries
