Input: Consider Input: Article: It is reasonable to say that every teenager can be affected by peer pressure at some point. Every day, in any high school, peer pressure has a major influence over the behavior of teenagers. It can be as subtle as being persuaded to be late for class or as extreme as a dangerous drug. Whether subtle or extreme, peer pressure can have damaging, sometimes life changing, and even serious results. "Teens don't often consider the long-term results that some behavior can cause," said Terri Price, a researcher. "Peer pressure can be very difficult to handle for many teens because of their fears of not fitting in". Peer pressure has always been part of teen life, but teens experience _ differently than their former generations did in the past. Sources of peer pressure have increased because of the Internet and other electronic communications. Recognizing peer pressure can be as simple as noticing that you have been asked to do something that you are not comfortable with. "Listen to your instinct , which is a sign for whether something is right or wrong. If it feels wrong, then most likely it is. "says Price. Teens are in a time of life when they are still discovering who they are. Many teens are influenced by peer pressure because of their insecurities . This can make them helpless especially when their self-control is weak or they lack healthy support, causing them to take risky behavior or turn to unhealthy support. Dealing with peer pressure is a topic of concern for teens. People can say, "Just say no," but the truth is that the statement is easier said than done.
Question: You can know whether a teen suffers peer pressure by watching _ .
Options: (A) whether he often surfs the Internet (B) whether he can get security (C) whether it is subtle or extreme (D) whether he feels comfortable with it

Output: D

Input: Consider Input: Article: Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms. Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago. Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger. "As new species of pests and diseases evolve and potentially the environment for them becomes more _ at higher latitudes, the pressure on the breadbaskets of the world is going to increase." Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species. "It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America." Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
Question: The purpose of Dan Bebber's research was to find _ .
Options: (A) if farmland could be moved to colder places thanks to global warming (B) if diseases and insects harmful to crops were going towards colder areas (C) if organisms were moving to the north and south poles (D) if the number of crop pests was increasing

Output: B
