Read the following article and select the best answer. Article: Contrary to popular belief, looking at someone's face alone is not enough to tell us whether they are roaring in celebration or screaming in frustration, researchers claimed.While people may believe they have the ability to read each other's faces, body language is the real clue that shows whether strong emotions someone is feeling are positive or negative. In a study, groups of participants were shown a series of facial expressions such as tennis players photographed just after winning or losing a point. In some cases the volunteers were able to see the player's full body, but in others they were only shown either their face or their body with the other removed. Participants could clearly tell whether the players were winning or losing when they were shown the full picture or just the body, but their guesses were no better than chance when based on the face alone. Those who were allowed to see the full image were convinced they had made their judgment based on the players' facial expressions even though results from the two other groups suggested otherwise. The researchers carried out a second study where participants were shown a wider range of faces showing emotions including joy, pleasure, victory, pain and defeat. Using photoediting software, the researchers attached the faces to bodies expressing the opposite emotion, and asked participants to act out the emotions they saw in the photos. The resulting poses were like the body poses in the photographs but not the facial expressions, demonstrating that people base their interpretation of strong emotions not on the face but the body. Dr Aviezer, who led the study, said, "These results show that when emotions become extremely intense, the difference between positive and negative facial expressions becomes unclear.The results may help researchers understand how our body interacts during emotional situations.For example, individuals may fail to recognize facial expressions, but if they are trained to process important body language, their performance may... Question: What did Dr Aviezer think of the results of the study? - Ridiculous. - Useless. - Unrealistic. - Helpful.
(Answer)

Ques: Read the following article and select the best answer. Article: As we get older, most of us worry about grey hair, wrinkles and maintaining a youthful body. But people often don't realize the voice needs looking after. Here, Mr. Rubin, a voice expert, reveals how to keep your voice youthful. Drink more fluid and avoid spicy food You need water for the vocal cords to vibrate well. The body must be kept hydrated enough to make the vocal cords operate well. Drinking 1.5 liters of water a day at intervals of 15 minutes is very important. Mr. Rubin advises avoiding foods with an annoying effect on the stomach, such as onions, chili, fizzy drinks and chocolate. Rest the throat and talk regularly The vocal cords can be scared if you use your voice during a bad cough. If you have a case of laryngitis with a cold, you should rest your voice for a day or two, and seek medical advice. Simply staying sociable and using your voice is very important. "As older people get less mobile, they can become socially isolated and speak less." says Mr. Rubin. "The elderly need to communicate with people more. By using the vocal cords, they enable the ageing process to slow down. " Improve your posture Good posture is essential to keeping the voice young, so we'd better stand properly. Exercise helps you take deeper breaths as it means there is better airflow through the voice box, producing a stronger tone. Sing in the shower This is one of the best ways to preserve your voice, as it keeps the larynx muscles strong while the steam lubricates the voice box. "Singing is gymnastics for the voice," says Mr. Rubin. Joining a choir is one of the best ways to preserve a youthful tone.

Question: Read the following article and select the best answer. Article: Looking good, feeling good Born to a model mom and a suit maker dad, fashion was actually in my blood. I always had a strong desire to dress in a certain way and to stand out from the crowd. I made my own toys when I was a young child and sewed my first skirt at just 10 years old. A friend's mother took one look at my skirt and told me that I should be a patternmaker. In high school I started making my own clothes, mostly changing other things because I never liked anything how it was when I bought it. During the last two years of school, I worked part-time for a small business that made hand-painted silk clothing and bags. The owner became the teacher who got me into design in the first place. Another useful bit of work experience then came when I worked at a showroom during fashion week and found it very exciting. From there I worked at a top clothing store while I got my business started. For my business I started out with the idea that everything I did would be hand-made and one-of-a-kind, specially made for one individual who hopefully had the same tastes as me. Every morning I jumped out of bed, went to my studio and worked on my projects. This just showed how enthusiastic I felt about my work. And at night I even dreamed of new designs! Fashion design is _ art. What I mean is that it's something close to you and something you can touch and feel, and actually interact with. My advice to any young person who wants to be a fashion designer is to get the basic skills early on, such as sewing and pattern-making. Even if you end up specializing, it's really important to understand all aspects of design in order to make high-quality clothes. Also, if you dream of having your own clothing line, the best thing to do is start wearing your clothes. You have to try and do this because that's the way you're going to develop something that's all yours and unlike anyone else's. I passionately believe that the right clothing can make people feel better and give them more confidence. Question: What advice does the author give to those who want to be fashion designers? - Creating basic designs in high school. - Wearing high-quality clothes all the time. - Looking at what their friends are wearing. - Deciding what is unique about their clothes.
Answer:
Deciding what is unique about their clothes.
