In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". 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.

Article: If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else. In September, scientists announced at the National Snow and Ice Data Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker. Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. "There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area," they say. The changes happening in the Arctic are a warning for the entire world . As polar expert Walt Meier puts it, " _ Some scientists worry that Arctic sea ice may be going from a downward spiral to a "death spiral", one from which there is no escape. As more ice melts , more dark open water appears. The darkness absorbs more heat, which speeds up the pace of melting. Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. "The melting is happening faster in the real world than it has in the models," says Nick Toberg.
Question: Nick Toberg may agree that _ .
Options: (A) the ice in the North Pole will stop melting (B) the ice in the North Pole is melting faster than expected (C) the ice in the North Pole will melt before 2030 or even earlier (D) the ice in the North Pole will not disappear until the end of the century
answer:
B

Article: By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat? To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.
Question: In order to exist in the future, people have to _ .
Options: (A) move to other planets (B) produce rain in laboratories (C) build new laboratories for food research (D) increase the food production or look for other food sources
answer:
D

question:
Article: It seems that men are under more stress when stuck in a traffic jam than women. British researchers for the GPS company TomTom used saliva to decide the stress levels. Levels for women were far lower than levels for men. Most of the people taking part in the research, men and women, reported that they didn't feel any stress at all. Even with that report, their saliva told a different story. In fact, people are under stress while in traffic and not even realizing it. That does not mean good things for health. People can only do something about their health if they know something is wrong. Men are more likely to have much less patience than women. That is why their stress levels are much higher than women when they are sitting still in traffic. Men want to get where they are going now. 72% of people taking part in the research drove every day. Of course, 86% believed that traffic affected their lives in a bad way. Being stuck in traffic after a stressful day at work could raise the level to an even higher level. The more likely they are to get further stressed. Stress from being stuck in traffic is also related to a higher chance of getting into car accidents. It is wise to avoid driving when already feeling stressed. Calm down for a few minutes, take a deep breath and drive as safely as possible. Driving with too much stress could cost you or someone else their life. It is not worth the danger. Reduce the amount of stress that you are experiencing before getting into the car and find ways to relax more when stuck in traffic. One way to relax is to have soothing music to play during these times.
Question: What people reported were different from the research findings because _ .
Options: (A) they didn't know they were stressed (B) they didn't know how to describe their feelings (C) they didn't want to share their true feelings with others (D) they didn't want to admit something was wrong with themselves
answer:
A
