Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Input: Consider Input: Article: Why doesn't the unemployment rate ever reach zero? Economists, who generally believe that supply tends to meet demand, have long thought about this question. Even in good times, i.e. not now, there are people who can't find work. And even in bad times, i.e. now, there are job openings. With over 14 million people out of work and looking for a job, you would think every available job would be filled. But that's not the case. Not now and not ever. On Monday, the Nobel Prize committee awarded the prize for economics to the three scholars who have done the most to explain this phenomenon. Two of the winners are Americans, Peter Diamond of MIT and Dale Mortensen of Northwestern. The third winner is Christopher Pissarides, who teaches at the London School of Economics and was born on Cyprus. Like most of economics, what they have found about why the jobless and ready-employers don't find each other seems obvious. You have to find out there is job opening you are interested in. Employers need to get resumes . It takes a while for both employers and employees to make the decision that this is what they want. And these guys came up with a frame-work to study the problem of why people stay unemployed longer than they should and what can be done about it. So what would today's Nobel Prize winners do to solve the current problem of the unemployed? And does the awarding of the prize contribute to the politicians' lowering joblessness? Speaking from his north London home, Pissarides told The Associated Press the announcement came as "a complete surprise" though his work had already helped shape thinking on both sides of the Atlantic. For example, the New Deal for Young People, a British government policy aimed at getting 18-24-year-olds back on the job market after long periods of unemployment, "is very much based on our work," he said. "One of the key things we found is that it is important to make sure that people do not stay unemployed too long so they don't lose their feel for the labor force," Pissarides told reporters in London. "The ways of dealing with this need not be expensive training - it could be as simple as providing work experience."

Input: Consider Input: 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.

Input: Consider Input: Article: The vast jungles of the Amazon rainforest are home to tribes mostly isolated from the outside world,whose way of life,largely unchanged for hundreds of years,is now increasingly threatened by modern civilization. Now, scientists discover they can monitor these"uncontacted tribes"using satellites,which would allow inexpensive and safe tracking of these tribes in order to protect them from outside threats. In order to help conserve these uncontacted Indians,researchers need accurate estimates of their populations.One way to collect this data involves flying over their villages,but such overflights are both expensive and could fill these native peoples with fear.Another strategy involves meeting individuals on the ground,but among other risks,scientists could accidentally spread disease to members of the tribes. Instead,scientists investigated whether satellite imaging could monitor uncontacted tribes. The result was inspiring.They confirmed their locations and measured the sizes of their Village,houses and gardens."We can find isolated vinages with remote sensing and study them over time."Walker told Live Science."We can ask:Are they growing?Do they move?" Surprisingly,based on the sizes of the houses and Villages,the scientists find the population densities of these isolated villages are about 10 times greater,on average,than other villages of native Brazilian peoples.This may be due to the fact that they have to live closer together because they are not as good at clearing the forest,since they lack modern devices like chainsaws and tractors,the researchers said.The tribes may also be afraid of spreading out due to fear of being attacked by outsiders,Walker said. The researchers now plan to focus on 29 more isolated villages to"look at their ecology--that is.distance from rivers and roads--and use this to model where else we can find more isolated villages,"Walker said.
