Read the following article and answer the question. Article: My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: "What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?" He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation is incredible . We're on a more different curve than we used to be. One thing I'm looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you'll be able to sample things before you buy them. But the question will be how I find what I'm looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded , with whom I might really want to communicate? I want to find those people but it's hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It's going to be very interesting, I think. Question: The writer is looking forward to some real software agents so as to _ . Answer:

A: help find the correct information needed

Read the following article and answer the question. Article: When you don't speak, you may be still communicating. It is true that you may not wish to say anything. But your very silence may show your wish to be left alone or to stay uninvolved, which is the message you want to send. So it has been said that while we speak with our vocal organs, we _ with our whole bodies. All of us communicate with one anther nonverbally , as well as with words. Sometimes we know what we are doing with the use of gestures such as the thumbs-up sign to indicate that we approve. But most of the time we are not aware that we are doing it. Body language serves a variety of purpose. Firstly it can replace verbal communication, as with the use of gesture. Secondly, it can modify verbal communication. Loudness and tone of voice is an example here. Thirdly it regulates social interaction: turn taking is largely governed by non-verbal signals. Fourthly it conveys our emotions. Finally it conveys our attitude towards ourselves and towards the people we are communicating with. _ is particularly important for successful cross-cultural communications. Every culture has its own body language. So in order to achieve a more successful cross-cultural communications, we heed not only what to say but also how to say it appropriately. Observation shows that a truly bilingual person switches his body language at the same time he switches language. Question: Body language varies _ . Answer:

- hoarding is a serious problem that needs concern.
- the main reason of hoarding is the economic burden.
- food preparation becomes easier if a person is a hoarder.
- hoarded items can't be piled higher than a person's head.

Read the following article and answer the question. Article: A hoarder is someone who is unable or unwilling to throw items away, and the disposal of items causes them considerable pain. When people hoard a massive amount of objects, it takes over the inhabitable spaces of their home. As the collection grows, they are unable to do simple , _ activities such as cooking a meal or watch TV. Sometimes the hoarding is so severe that parts of their homes become inaccessible. But among the many problems that such behavior brings about, the most significant are the health risks. Once hallways and windows are blocked, hoarders are at the risk of dying in a fire, since they no longer have a clear path of evacuation . Things that are piled up high can fall on top of the homeowner, or a person trying to climb over a pile of objects can experience a fall. There is also the problem of sanitation . Areas where food can't be properly cleaned begin to attract insects, and bathrooms that are full of many possessions can no longer be washed. Unfortunately, the serious effect of the problem can become worse for two reasons. One is that since the behavior progress behind closed doors, people can accumulate collections of objects for years before friends or family members become aware of the problem. A second reason is that hoarders often don't recognize that they have a problem, and will continue to live in denial until they get professional help. When attempting to make a diagnosis, psychologists don't regard hoarding as a disorder in itself. Instead, it's often seen as a symptom of obsessive-compulsive disorder , depression, or anxiety. The mental health community has only recently begun an intensive study of boarding, and more research is needed in order to understand its causes and find effective treatment. Question: We can infer from the passage that _ . Answer:
****
A: hoarding is a serious problem that needs concern.

Problem:OPTIONS:
- People without a stroke can drink more alcohol than those having a stroke in middle age
- There is a higher possibility that heavy drinkers will have a stroke in middle age
- Drinking alcohol has been regarded as the most dangerous factor in strokes
- The amount of alcohol taken by men should be twice than that taken by women.

Read the following article and answer the question. Article: Drinking more than two alcoholic drinks daily in middle-age may raise your stroke risk more than traditional factors such as high blood pressure and diabetes , according to new research in the American Heart Association journal Stroke. In a study of 11,644 middle-aged Swedish twins who were followed for 43 years, researchers compared the effects of an average of more than two drinks daily ("heavy drinking") to less than half a drink daily ("light drinking"). The study showed that: *Heavy drinkers had about a 34 percent higher risk of stroke compared to light drinkers. *Mid-life heavy drinkers (in their 50s and 60s) were likely to have a stroke five years earlier in life _ of genetic and early-life factors. *Heavy drinkers had increased stroke risk in their mid-life compared to well-known risk factors like high blood pressure and diabetes. *At around age 75, blood pressure and diabetes appeared to take over as one of the main influences on having a stroke. Past studies have shown that alcohol affects stroke risk, but this is the first study to pinpoint differences with age. "We now have a clearer picture about these risk factors----how they change with age and how the influence of drinking alcohol shifts as we get older," said Pavla Kadlecova, M.Sc., a statistician at St. Anne's University Hospital's International Clinical Research Center in the Czech Republic. Researchers analyzed results from the Swedish Twin Registry of same-sex twins who answered questionnaires in 1967-1970. All twins were under age 60 at the start. By 2010, the Registry had provided 43 years of follow-up, including hospital discharge and cause of death data. Researchers then sorted the data based on strokes, high blood pressure, diabetes and other cardiovascular incidents. Almost 30 percent of participants had a stroke. They were categorized(......) as light, moderate, heavy or non-drinkers based on the questionnaires. Researchers compared the risk from drinking and health risks like high blood pressure, diabetes and smoking. Among... Question: What does the passage mainly tell us? Answer:
****
A:
There is a higher possibility that heavy drinkers will have a stroke in middle age
