However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity. Of course, astronauts can still produce tears . But crying is much more difficult in space, according to The Atlantic in January. Without gravity, tears don't flow down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go -- they just stick to your eyes. In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes. They just stay there." Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging like crazy," Feustel told his teammate during the walk. Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait -- "When the tears get big enough, they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic. There are lots of small things -- things like crying -- that we are so used to on Earth. We usually _ until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp , because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up everything in their stomach, according to the UK National Space Center. Therefore,... Question: What effect do tears have on astronauts? - They cause physical pain. - They bring comfort to them. - They make their vision clearer. - They float around and cause trouble.
They cause physical pain.

Read the following article and select the best answer. Article: In England recently three foreign gentlemen came to a bus stop and waited . About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way . Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked embarrassed ( . No one had told them about the British custom of lining up for a bus that the first person who arrives at the bus stop is the first person to get on the bus . Learning the language of a country isn't enough. If you want to have a pleasant visit, find out as much as possible about the manners and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is supposed to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn't agree. But in many parts of India a shake of the head means agreement. Nodding your head when you are given a drink in Bulgaria will most probably leave you thirsty . In that country, you shake your head to mean 'yes'-- a nod means 'no' . At a meal in countries on the Arabic Peninsula, you will find that your glass is repeated refilled as soon as you drink up . If you think that you have had enough , you should take the cup or glasses in your hand and give it a little shake from side to side or place your hand over the top. In Europe it quite usual to cross your legs when you are sitting talking to someone even at an important meeting. Doing this in Thailand, however, could bring about trouble . Also, you should try to avoid touching the head of an adult ----it's just not done in Thailand . Question: To cross one's legs at an important meeting in Europe is _ . - a common habit - an important manner - a serious trouble - a bad manner
(Answer)
a common habit

Ques: Read the following article and select the best answer. Article: Have you ever been stuck for hours on a hard math problem? If you sat there for some time you might eventually solve it, but scientists say that daydreaming might be a much better way to tackle difficult tasks. In fact, daydreaming has long been misunderstood. It's considered to be a bad thing and often associated with laziness. "We're harsh on ourselves if we catch ourselves mind wandering," says Professor Kalina Christoff from the University of British Columbia in Canada. But the truth is that some of the most important scientific discoveries came about because scientists allowed their minds to wander. For example, Albert Einstein began his theory of relativity when he daydreamed about riding a beam of sunlight to the edge of the universe. And now, research has shown that normal people can also improve their problems solving ability in the same way, reported The Telegraph. In a study, 145 people aged between 19 and 32 were asked to list as many unusual uses as possible for everyday objects. Some of them were given a 12-minute break while the others were not allowed any break from the task. People on the break did not simply relax--some of them were told to carry out a tiring memory task while others did an easier task. Scientists found that people who did the easier task were daydreaming a lot. They thought about personal issues in the past or in the future because their mind was at ease. After the break, all participants were asked to return once again to the task of listing unusual uses for everyday objects. It was found that daydreamers improved their performance by 40 percent, while all the other people, including those who didn't have a break and who did tiring tasks during the break, performed the same as before. "People think that when the mind wanders away, it just gets turned off--but we show the opposite," explained Christoff."A more playful attitude might allow you to call in more resources ." So when you are struggling to solve complicated problems, it might be better off if you switch to a... Question: . What did the scientists discover in the experiment? - People's minds turned off as they daydreamed. - The group that were given hard memory tasks performed best. - People who had a break showed improvement in the task. - Daydreaming could improve people's problem-solving abilities.
Ans: Daydreaming could improve people's problem-solving abilities.
