Read the following article and select the best answer. Article: Each year, road accidents kill a million people and injure millions more. The economic costs are greatest for developing countries. Earlier this year, the United Nations called for a campaign to improve road safety. One way to avoid accidents is better driving. Another is better roads and bridges. Engineers in the Unites States have designed ten new concrete mixtures that they think could make bridges last longer. Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University. He says bridges made of concrete now last about twenty-five to thirty-five years. But he says the new mixtures might extend that to seventy-five or even one-hundred years. Concrete is made of stone, sand, water and cement . The materials in the cement hold the concrete together. Ancient Romans built with concrete. Yet strengthened concrete bridges did not appear until the late 1800s. People keep looking for new ways to improve concrete. Professor Tikalsky says it is one of the most complex of all chemical systems. The new mixtures designed by his team contain industrial waste products. He says these make the concrete better able to resist damage from water and salt over time. One of the products is fly ash. This is released into the air as pollution when coal is burned. Professor Tikalsky says particles of fly ash are almost exactly the same size and chemical structure as Portland cement. _ is the most costly material in concrete. So using fly ash to replace some of it would save money. The federal government is paying for part of the research. Engineers anywhere can use the technology. Professor Tikalsky says some of the ideas have already been put to use in China, the Philippines and other countries. Question: What does the passage mainly tell us? - The causes of road accidents. - The advantages of fly ash. - The measures of avoiding road accidents. - Latest information about long-life concrete bridges.

Read the following article and select the best answer. Article: Most recently, it's very common in students who need a parent present for job interviews. Naturally, it's easy to blame the students in these situations, but the bigger problem is us. We--as parents--are so eager to shelter our kids that we fail to realize that this in itself is harming them.As the mother of two young sons, I have to remind myself constantly that the biggest responsibility I have as a parent is to help them develop the skills needed to live in, to live without me.So, I'll let them fail. I'll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow.And failure -- along with loss, heartbreak, disappointment, etc.-- will be part of growth for them.Call me the anti-tiger mom, but leaving them alone, is my way of helping them become equipped to fit in this world as we know it today.From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish. My children now are becoming little masters of compromise, but they try to negotiate everything now.It's a small price to help them learn a skill they'll use for the rest of their lives, including when I don't accompany them on job interviews. Question: According to the author, what is beneficial to kids' development? - Sheltering them. - Keeping them safe. - Leaving them alone. - Blaming them.
(Answer)
Leaving them alone.

Ques: Read the following article and select the best answer. Article: At one time no one could travel on an English road faster than four miles an hour. That was the law until 1896. A man had to walk in front of a car which could not go faster than the man. At night the man had to carry a red lamp. Once Charles Rolls brought a car from France to England, but he wanted to drive faster than four miles an hour. In order to have no trouble with the police, he had a talk with some of the police officers, who ordered their policemen to look the other way when the car came along the road. This was a good plan in the country, but not so easy to follow in the busy streets of London. One night Rolls and some friends started from London on their journey to Cambridge. One of the men walked in front with the red lamp, but he walked as fast as he could. The police became very interested in walls and shop-fronts when they heard the car and not one of them saw it. They reached a hill, but what a waste of time it was to drive down the hill at four miles an hour! Rolls was getting ready to jump into the car, but then he noticed a policeman who was not looking the other way. The slow car reached him. "Good evening," said the policeman, looking at the car. "Good evening," said Rolls, holding the lamp. "One of these horseless things," said the policeman, looking at it with interest. "Yes," said Rolls, and waited. "I've often wanted a ride in one, but of course policemen can't buy things like that." He turned and looked hopefully in Rolls's face. "Jump in," said Rolls. "Thanks," said the policeman, and did so. "Now," he said, sitting down, "You can let it go just as you like down this hill. There isn't another policeman on this road for a mile and a half." Question: The policemen were told "to look the other way" so that _ . - they could watch the car coming from the other direction - Rolls's car could go faster than four miles an hour - they could make sure no one was in the way - the car would not hit them on the road
Ans: Rolls's car could go faster than four miles an hour

Question: Read the following article and select the best answer. Article: "Last week," Dr. P said "I was invited to a doctors' meeting at the R. Hospital. In one of the rooms a patient, an old man, got up from his bed and moved slowly towards me. I could see that he hadn't long to live, but he came up to me and placed his right foot close to mine on the floor." "Frank!" I cried with surprise. He couldn't answer as I knew, but he tried to smile, all the time keeping his foot close to mine. My thoughts raced back more than thirty years--to the dark days of 1941, when I was a student in London. The scene was an air-raid shelter , in which I and about a hundred other people slept every night. Among them were Mrs. West and her son Frank, who lived nearby. Sharing wartime problems, we got to know each other very well. Frank interested me because he was not normal . He had never been normal, ever since he was born. His mother told me he was 37 then, but he had less of a mind than a baby has. Mrs. West, then about 75, was a strong, able woman, as she had to be of course, because Frank depended on her completely. He needed all the attention of a baby. One night a policeman came into our shelter and told Mrs. West that her house had been all destroyed. That wasn't quite true, because the West went on living there for quite some time. But they certainly lost nearly everything they owned. When that kind of thing happened, the rest of us helped the unlucky ones. So before we separated that morning, I stood beside Frank and measured my right foot against his. They were about the same size. That night, then, I took a spare pair of shoes to the shelter for Frank. As soon as he saw me, he came running--and placed his right foot against mine. After that, he always greeted me in the same way. Question: How did Dr P know that the patient was Frank? - He was told that Frank was in the hospital. - He was invited to study Frank's illness. - Frank greeted him in a special way. - Frank's name was written on the door.
Answer:
Frank greeted him in a special way.
