Q: Read the following article and answer the question. Article: When policy experts debate climate change solutions, they often talk about "a price on carbon." They are arguing about whether companies should pay when they put carbon pollution in the air. Proponents say that it's simple economics -- if it's free to pollute, you'll get a lot of pollution. Opponents claim it will raise the cost of energy that's produced from high carbon sources, like coal. But here's the secret that most people seem to be missing: There already is a price on carbon, and it's paid by the taxpayers. Carbon pollution, like every other form of pollution, has an impact on the environment. Throwing waste into a river will cause the fish to die and the people who drink the water to get sick.  And when you produce carbon pollution, you get climate change -- sea level rise, stronger storms, severe droughts, damage to agriculture, and more. All of those impacts cost money. Insurance rates go up when storms get more destructive. Taxes increase when cities have to rebuild bridges and roads. Military budgets go up when droughts and population changes cause conflicts. Not to mention impacts on agriculture and health care costs. In other words, the price on carbon is what we all pay when there is no market force to limit the pollution that causes climate change. So the debate is really about who will pay that price -- the companies who are making a profit from the fossil fuels, or the taxpayers who pick up the cost now? Right now, we have private profit and public cost. It's just like if we allowed every business to throw its garbage in the street because it's too expensive to have it moved away properly. Does it add a little bit to your dinner check to require that restaurants dispose of their trash properly? Sure. But it would be more expensive for you if the city had to clean the streets of their garbage every day. So just like we put a "price on garbage" we need a "price on carbon pollution." Now, a "price on carbon pollution" can mean a lot of things. You could tax companies based on the amount of... Question: What do the policy experts argue about carbon pollution? Answer:
Answer: Whether the companies should pay for it.

Q: Read the following article and answer the question. Article: Half a year before graduation from college, my son David began to seek a job. Due to the financial crisis, the competition was ever-fierce. My son targeted a company that was located in a coastal city. It was intended to employ only one person among more than twenty candidates, I said to David, "You should not harbor too much hope for fear that you would feel terribly disappointed when you fail." He said to me, "I am not afraid of disappointment. As long as I try, there will always be hope!" Three young men could enter the final round, which would later decide one person to be employed. Everything seemed to go quite well and David entered the final round in a week. Unexpectedly, the interview was unbelievably simple, during which the interviewer only chatted with them for a while. The interview strategies my son prepared were not useful at all. The interviewer said the company would inform them of the result in 3 days. On the morning of the third day, David received the text from the company that he was not employed. David felt disappointed. In nightfall that day, David suddenly told me excitedly on phone that he had been employed. Greatly surprised, I asked him, "What's the whole matter?" David told me that he received another text saying that he was employed. David felt very confused about it. Later he found out the first text sent to him was also part of the test in the interview. Three men received the same text this morning and only David's reply was satisfying to the company. I asked my son, "How did all of you reply?" My son said, "One did not reply. The other said "goodbye" and I said "thank you"." Only then did I know that my son's "hope" came in that way. That is, when you feel disappointed, do not forget to say "Thank you" to the one who disappoints you. Actually, it is a piece of cake to say "Thank you". Saying "Thank you" shows respect for others' work and demonstrates your grand generosity. Therefore, while under the same condition, you will get the upper hand in terms of opportunities compared... Question: Which of the following is True about David's final round interview? Answer:
Answer: David's preparations for the interview were not used.

Q: Read the following article and answer the question. Article: As each semester begins, my colleague greets his students wearing a jacket and tie. "You make only one first impression," he says. So while the rest of the semester he teaches class in his usual, more casual clothes, the first week he presents a different image. His thought is that students will remember their first meet positively and more readily think highly of him as the semester goes on because that favorable first impression has an influence on them. The sequence   that we meet matters in how we judge subsequent   information. The big influence of first impressions is related to the halo effect, where the perception   of positive qualities in one thing or part gives rise to the perception of similar qualities in related things or in the whole. Here is an example: You meet a friendly person at a party and later are asked to collect money for a worthy cause. You call that person because you think she will make a contribution. In reality, there is no connection between being pleasant and being generous. Yet the halo effect leads you to think that the two are related. The halo effect is powerful, but it is questionable whether it matters much in long-term relationships, such as that between teacher and student. While dressing up may make students think the teacher must know his subject matter because he creates a professional first impression, the effect wears thin if the person turns out to be a poor teacher after all. First impressions matter but they don't have the final word. Facts speak louder. If you had never seen or heard of Einstein, the first time you saw him your impression would most likely be negative. Now his face is connected with genius  , not madness because he is the person who has come to define what genius is. The problem is that few of us are Einsteins and we often don't get the chance to change a negative first impression. Question: The author uses the example of Einstein to show the importance of   _  .

Answer:
