Read the following article and answer the question. Article: The private automobile has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but has also led to traffic problems. For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools. Family life has been affected in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can't keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or is "showing off" by speeding or breaking other traffic laws. Mothers of victims of such accidents have formed an organization called MADD(Mothers Against Drunk Driving). These women want to prevent further tragedies . They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends. For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans. Question: What has been done to deal with the problem of drunk driving? Answer:

OPTIONS:
- Parents have paid more attention to their children.
- Some organizations have been set up against drunk driving.
- Mothers have tried to persuade their children not to drink alcohol.
- University students have asked the government to solve the problem.

Answer: Some organizations have been set up against drunk driving.

Problem: OPTIONS:

Q: Read the following article and answer the question. Article: I became what I am today at the age of twelve, on a freezing cold wet day in the winter of 1975. I remember the right moment, hiding behind a fragile mud wall, peeking into the alley near the frozen stream. That was a long time ago ,but it's wrong what they say about the past, I,ve learned, about how you can bury it, because the past claws its way out. Looking back now, I realize I,ve been peeking into that deserted alley for the last twenty-six years. One day in summer, my friend, Rahim Khan called from Pakistan. He asked me to come to see him. Standing in the kitchen with the receiver to my ear, I knew it wasn't just Rahim Khan on the line. It was my past of unatoned sins After I hung up, I went for a walk along Spreckels Lane on the northern edge of Golden Gate Park. The early afternoon sun sparkled on the water where dozens of small boats sailed, driven by a gentle breeze. Then I glanced up and saw a pair of kites with long blue tails, soaring in the sky. They danced high above the trees on the west end of the park, over the windmill, floating side by side like a pair of eyes looking down on San Francisco, the city I now call home. And suddenly Hassan5S voice whispered in my head: For you, a thousand times over. Hassan the hare-lipped kite runner. I sat on a park bench near a willow tree. I thought about something Rahim Khan said just before he hung up, almost as an after thought. There is a way to be good again. I looked up at those twin kites. I thought about Hassan. Thought about Baba. AU. Kabul. I thought of the life I had lived until the winter of 1975 came along and changed everything. And made me what I am today. Question: It can be inferred from the passage that _ . Answer:
Answer: something bad might have happened in the alley

input with options: Read the following article and answer the question. Article: Special ships that create clouds by sending seawater into the air could be the cheapest way of dealing with climate change, new research has found. The technique, known as "marine cloud whitening", would create clouds above the Pacific Ocean that would have a cooling effect by reflecting sunlight away from Earth. Nearly 2,000 wind-powered ships would cross the sea, getting seawater and sending it up through tall tubes. " When you send saltwater into the air, you create bigger and whiter clouds, and thus reflect more sunlight back into space," said David Young from the group of the study. The paper by Professor Eric Bickel and Lee Lane looked into the costs of the projects. It found that cloud whitening would reduce the effects of climate change this century for no more than PS5.3 billion. This is only a small part of the PS150 billion that leading nations are considering spending to cut CO2 emissions each year. It is also more than 25 times cheaper than the PS140 billion cost of another project which would copy the cooling effect of volcanoes. The authors also compared the cost benefits that reducing temperatures would have. They found every PS1 spend on other ways would have PS15 of benefits, however every PS1 spent on cloud whitening would bring PS2,000 of benefits. These would include the human costs on health and the influence on other fields. David Young said, "Marine cloud whitening could achieve as much for the planet as CO2cuts would, but with much less cost." But he warned that these techniques shouldn't be considered as a long-period way to deal with climate change. " It's important to note that this technique wouldn't reduce CO2emissions or deal with the causes of global warming, but would cover its effects." he said. Question: Compared to other projects, cloud whitening _ . Answer:
OPTIONS:
- has a greater effect on volcanoes
- will bring more benefits
- will benefit man's health most
- can reduce temperatures in a better way
output:
will bring more benefits
