[EX Q]: Article: Dear Editor, Recent reports have indicated an additional 1, 400 Marines are being sent to Afghanistan in the coming weeks. This means it costs over $1 million annually on the ground over there. I do place a higher level of blame on the policymakers who send soldiers off to kill and be killed in the field. I think the human race needs to think more about killing. One needs to do the _ : "Are these wars JUST?" I believe that all of our wars since 1945 have been illegal, under international law as well. I suggest that all your readers examine their conscience as it relates to the matter of making war. The fact that many soldiers are motivated by a strong sense of duty does not give them some unqualified moral right to support these wars or any other. It's responsible for all the troops, and the entire population, to determine whether the Afghan or Iraq wars are in accordance with  the development of the state. I wish someone would give me one or more logical reasons why we are still fighting in Afghanistan and what our goals are. I certainly don't understand it and neither do many who are more knowledgeable than I. Outsiders have tried unsuccessfully for centuries to conquer Afghanistan, and we seem to be no more successful. We are trying to develop a stable central government, but the country is badly divided into ethnic and tribal groups, and the current government is corrupt . Moreover, we are apparently regarded as undesirable occupiers by many of its people, most notably the Taliban.  If we are to continue spending billions every year in Afghanistan and killing hundreds of our people and many of theirs, our government must provide us with a reasonable explanation of why we are doing so and what we can expect to accomplish. George Myers

[EX Q]: Article: Abby Subark is a mother of two from Boston. "For my kids, I'm nervous. I don't know if they'll be able to achieve their American dream." She may be right. More than hard work or education, the best way to get rich in America is to be born rich. It is the case that somebody who is in the upper third of income, poor scores, in the bottom on tests when they are in eighth grade, is more likely to go to college and finish college than a poor kid with the top scores. That's what the working persons'  children are up against. The Economic Policy Institute finds it would take a poor couple with 2 children 9 or 10 generations to achieve middle class status. That's about 200 years. The hallmark   of American opportunity has always been the ability to do better than your parents. But compared with similar developed countries, the United States ranks fifth out of six for so-called intergenerational mobility  . If you look at the mechanisms   for upward mobility that were so readily available 50 years ago, they are becoming out of reach, like plentiful factory jobs with good wages and affordable education and health care. White families are twice as likely as blacks to be upwardly mobile. For most people in America today, _  If you started in the middle-income class, about 40 to 45 percent of what you are making right now is due to the fact that your parents were in the middle-income class. The rest is up to you. But for the millions of people who find themselves below the poverty line and the millions more who are the working poor, their starting point for the American dream leaves them painfully far away from the middle class. 
 Question: The main idea of the passage is   _  . 
 Options: (A) How the middle class comes about in the U.S. (B) It's hard to realize the American dream for the poor. (C) Wealth and social status depend on family background. (D) Upward mobility in America is never easy.

[EX Q]: Article: Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
