Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Some people may be born happy, while others are genetically negative, scientists have suggested in a study published late February in a British journal. Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter serotonin works within the brain. Serotonin, a hormone , passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant drugs regulate serotonin levels. Scientists had also identified three variants of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers. Researchers from the University of Essex in Britain showed participants a series of images, which were divided into three kinds: negative ones aimed at inspiring fear or stress such as a snake or person about to commit suicide, pleasant ones and neutral ones. The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction. In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see. Question: The article is mainly about _ . Options: A: the reason for the foundation of "happiness workshops" B: the link between people's mood and their gene C: the study on people's likes and dislikes D: the differences in people's attitude towards life
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: More than 2.25 billion cups of coffee are drunk throughout the world each day, and it's likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups. Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim. In one experiment, the white cup increased the intensity of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest. The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest. "Our study clearly shows that the color of a cup does influence our sense of the coffee taste," leading author Dr George Doorn, wrote in an article for The Conversation. "The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups," he said. "The potential effects may spell the difference between a one-time purchase and a return customer." Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate. Question: In which cup will coffee taste the sweetest? Options: A: A white cup. B: A blue cup. C: A transparent cup D: A brown cup
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: The other day I heard a few local musicians talking: "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm .""Nobody wants to pay musicians anything. I'm sick of all the people who want you to play without paying you."... One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I'm trying to find other places to play. I'm also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him. Attitudes are important. Whether they're positive or negative , they're all rubbing off on you. If you're around people who are always complaining or blaming others, it is possible that you will start doing the same as well. If you spend lots of time with people who don't support your dreams, it is time to take a look at the people you call "friends". There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don't become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream. Question: We can get the following information from the passage EXCEPT _ . Options: A: the younger musician is a positive person and would be a good friend B: one will start complaining if one spends too much time with negative people C: the exercise can help you keep close to really helpful friends D: one should avoid making friends with people who have lots of difficulties
