Example Input: Article: The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline. The term comes from the glacial activity of the Ice Age. At that time, the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier descended, however, it applied enormous force on those mountains, and they sank into the sea. As the mountains sank, ocean water charged over the lowest parts of the remaining land. And the highest parts of the former mountain range, nearest the shore, remained as islands. Marine fossils found here are 225 feet above sea level indicating the level of the shoreline prior to the glacier. The 2,500-mile-long rocky and jagged coastline of Maine keeps watch over nearly 2,000 islands. Many of these islands are tiny and uninhabited, but many are home to blooming communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands left behind by the glacier. Measuring 16 miles by 12 miles, Mt. Desert was very nearly formed as two distinct islands. It is split almost in half by Somes Sound, a very deep and very narrow stretch of water seven miles long. For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, has afforded summer homes for the wealthy. Recently, though, Bar Harbor has become a new arts community as well. But the best part of the island is the unspoiled forest land known as Acadia National Park. Since the island sits on the border between two different geographical zones, the park supports the plants and animals of both zones. It also lies in a major bird migration lane and is a resting spot for many birds. The establishment of Acadia National park in 1916 means that this natural monument will be preserved and that it will be available to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, hiking, cycling, and boating. Or they may choose to spend time at the museum learning about the Stone Age inhabitants of the island.
Question: The large number of small islands along the coast of Maine is the result of _ .
Options: (A) the drowning of the Maine coastline (B) glacier's forcing mountains into the sea (C) the irregularity of the Maine coastline (D) ocean water's flooding the mountain range
Example Output: B

Example Input: Article: Downloading music over the Internet is pretty common among high school and college students. However, when students download and share copyrighted music without permission, they are against the law. A survey of young people's music ownership has found that teenagers and college students have an average of more than 800 illegally copied songs each on their digital music players.Half of those surveyed share all the music on their hard drive , enabling others to copy hundreds of songs at any one time. Some students were found to have randomly linked their personal blogs to music sites, so as to allow free trial listening of copyrighted songs for blog visitors, or adopted some of the songs as the background music for their blogs. Such practices may be easy and free, but there are consequences. Sandra Dowd, a student of Central Michigan University, was fined US$7,500 for downloading 501 files from LimeWire, a peer-to-peer file sharing program. Sandra claimed that she was unaware that her downloads were illegal until she was contacted by authorities. Similarly, Mike Lewinski paid US$4,000 to settle a lawsuit against him for copyright violation . Mike expressed shock and couldn't believe that this was happening to him. "I just wanted to save some money and I always thought the threat was just a scare tactic ." "You know, everyone does it," added Mike. The RIAA (Recording Industry Association of America), the organization that files lawsuits against illegal downloaders, states that suing students was by no means their first choice. Unfortunately, without the threat of consequences, students are just not changing their behavior. Education alone is not enough to stop the extraordinary growth of the illegal downloading practice.
Question: Why is it common for students to download copyrighted music?
Options: (A) They don't think that they will be caught. (B) They want their friends to know that they are smart. (C) They think it is a good way to make some extra money. (D) They are against copyright protection over Internet music.
Example Output: A

Example Input: Article: In 1987, while serving as the public affairs officer at Fort Bragg, I would frequently visit the local high schools to speak to the students about the Army. As alieutenant colonel , I found it particularly rewarding to talk with the teenagers about the benefits of military service, if only for a few years of their lives. During one of these visits, I reported to the secretary in the principal's office to let her know that I was here for the third-period class. I was a little surprised when she told me. "The principal would like to see you before you go to the class." As I entered his office, I was greeted by a gentleman who appeared to be in his late thirties, and he welcomed me with a smile and a handshake. "You don't remember me, do you?" he said. I looked closely at the face again and could not recall where we may have met before. "You were my company commander in basic training at Fort Jackson in 1970," the principal said. "Let me help you out," he suggested. "You gave me a three-day pass to go home and see my newborn baby." I immediately remembered the incident! "Yes," I said. "I remember now." It was the only three-day pass I had issued because the soldiers were on their way to Vietnam immediately after they finished training. But I knew if I did not let him go home to see his son and _ , I would regret denying the opportunity he had to be with his family. "Come on, Colonel. I'd like to introduce you to 'the baby'. He's in your third-period class. By letting me go see him, you gave me a reason to stay focused and to come home safe from that war. Thank you , sir." It was the most rewarding class I had ever given, and I had no problem in telling the students about the bonds of friendship and the values that Army life can provide...and that can last a lifetime.
