Question: Read the following article and answer the question. Article: Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of"virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example.consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East, get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products Question: What is the best title for the passage? Answer:
OPTIONS:
- Crops and Virtual Water
- Import and Export of Water
- Benefits of Virtual Water
- Water's worldwide travels
Water's worldwide travels

Read the following article and answer the question. Article: We start finding things laughable -- or not laughable -- early in life. An infant first smiles at approximately eight days of age. In his book Beyond Laughter, psychiatrist Martin Grotjahn says that the earlier infants begin to smile and laugh, the more advanced their development is. Studies revealed   that children who did not develop these responses "developed a schizophrenic psychosis   in later life, or simply gave up and died". Between the ages of six months and one year, babies learn to laugh for essentially the same reasons why they will laugh throughout their lives, says Dr. Jacob Levine. He says that people laugh to express mastery over an anxiety. Adult laughter is more subtle  , but we also laugh at what we used to fear. The feeling of achievement, or lack of it, remains a leading factor. Giving a first dinner party is an anxious event for newly-weds. Will the food be good? Will the guests get along? All goes well; the party is over. Now they laugh freely. Their pleasure is from recalling the evening's activities. They couldn't enjoy the second pleasure without the first. Laughter is a social response caused by signals. Scientists have not determined a brain center for laughter, and they are puzzled by patients with certain types of brain damage who go into laughing with no apparent reason. The rest of us require company and a reason to laugh. Another reason why laughter is pleasurable is because of the physical feeling involved. According to Dr. Levine, we can measure our adjustment to the world by our capacity   to laugh. When we are secure about our abilities, we can make fun of our weakness. If we can laugh through our anxieties, we will not be overpowered   by them. The ability to laugh starts early, but it takes a lifetime to perfect. Says Dr. Levine, "When social relationships are mastered, when individuals have mastered... a peaceful relationship with themselves, then they have ... the sense of humor." And then they can throw back their heads and laugh. Question: What is the best title of the passage? Answer:
OPTIONS:
- Beyond Laughter -- A New Book with Fruitful Findings
- Smiling -- A New Mastery over Anxieties
- An Important Sign of Confidence and Success
- The Function and Meanings of Smiling

Answer: The Function and Meanings of Smiling

Read the following article and answer the question. Article: People are always talking about "the problem of youth". If there is one--which I take leave to doubt--then it is older people who create it, not the young themselves. Let us get down to something basic and agree that the young are after all human beings--people just like their elders. There is only one difference between an old man and a young one: the young man has a beautiful future before him and the old one has a splendid future behind him and maybe that is where the _ is. When I was a teenager, I felt that I was just young and unknown--that I was a new boy in a huge school, and I would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking. I find young people exciting. They have an air of freedom, and they have not a dull promise to mean ambitions  or love of comfort. They are not anxious social climbers, and they have no devotion to important things. All these seem to me to link them with life, and the origins of things. It is as if they were in some sense from outside space and lovely contrast with us suburban people. All that is in my mind when I meet a young person. He may be ill-mannered, self-confident, but I do not turn for protection to boring cliches  about respect for elders as if the age is a reason for respect. I accept that we are equals, and I will argue with him, as an equal, if I think he is wrong. Question: From the text we can see the writer's attitude towards the young is   _  . Answer:
OPTIONS:
- kind and satisfied
- considerate and understanding
- angry and unpleased
- hopeless and boring

Answer: considerate and understanding
