Example Input: Article: When young people begin to live independently, home-hunting can bring some stress. But they would do well to remember that a new alternative is available--micro-home. Called "tiny houses", these houses have all living necessities in a small package, including kitchen, bedroom and bathroom. Generally under 50 square meters, most tiny houses accommodate just one or two people though some claim the space for more. What's lost in size is not lost in design as these homes are often quite unique and modern in design. Besides an attractive appearance, tiny houses can also have unique practical features. Making the best of urban space, the 72- to122-centimeter-wide Keret House in Warsaw, the world's narrowest home, fills in an alley. The Ecocapsule home uses solar power, wind power and rainwater collection to enable its owner to live practically anywhere. A system of rails allows the DALE micro-home to adjust room size and number as well as adding the option of an open or enclosed courtyard. Visually appealing as micro-homes are, there are a few drawbacks to consider before getting cozy on a mini-couch. Moving into a tiny house requires the removing of most non-essentials, regardless of the emotional connection to them. Guests will also mostly be out of the question as the limited space may even cause a solitary individual to experience some cabin fever . And finally, a micro-home is likely a temporary living option for most people since they will probably start families and acquiremore possessions. Though the limitations will scare some, there is usually a benefit. A small size results in a small price tag and small bills, making tiny houses easier to save up for and budget. And though you won't have much stuff around the house, this can provide the comfort of simple living and repairs. Micro-homes are also practically mobile and have eco-friendliness that can't be matched by other homes. They probably aren't for everyone or forever, but when it comes to your next (or first) home, they could be just what you need.
Question: Micro-homes are especially fit for _ .
Options: (A) a young couple in hope of settling down permanently (B) an individual constantly suffering from cabin fever (C) a college graduate on a tight budget for the time being (D) a family of five in favor of environmental protection
Example Output: C

Example Input: Article: The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color.If they can sense color differences, then perhaps we, too, are affected by color without knowing it.Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics should never be packed in brown.These discoveries have grown into a whole subject of color psychology. Some of our preferences are clearly psychological.Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement.Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind.People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure.Red is exciting.Pure blue has exactly the opposite effect; it is a calming color.Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
Question: The passage tells us that salesmen have _ .
Options: (A) tried colors on blind people (B) found out that colors affect sales (C) developed a special subject of color psychology (D) discovered the relationship between color and psychology
Example Output: B

Example Input: Article: There was one shop in the town of Mufulira which was widely known for its racial discrimination. It was a drugstore .While Europeans were served at the counter ,a long line of Africans queued at the window and often not only were kept waiting but were treated rudely by the shop assistants .One day I was determined to make a public protest against this kind of thing ,and many of the schoolboys in my class followed me to the store. I simply went into the shop and asked the manager politely for some medicine. As soon as he saw me standing in the place where only European customers were allowed to stand ,he shouted at me in a bastard language which is only used by a boss when speaking to his servants .I stood at the counter and politely requested in proper English that I should be served .The manager became angry and said , "Even if you stand till Christmas ,I will never serve you ." I went to the District Commissioner's office .Fortunately ,he was out ,for _ however ,I saw a young District Officer who was a friend of mine .He was very concerned to hear my story and told me that all I had to do was come to him personally and he would buy my medicine for me .I protested that that was not good enough .I asked him to accompany me back to the store and to make a protest to the manager .This he did ,and I well remember him saying to the manager , "Here is Mr. Kaunda who is a responsible member of the Urban Advisory Council, and you treat him like a common servant ." The manager of the drugstore apologized and said , "If only he had introduced himself and explained who he was ,then ,of course ,I should have given him proper service." I had to explain once again that he had missed my point .Why should I have to introduce myself every time I went into a store...any more than I should have to buy my medicine by going to a European friend ? I want to prove that any man of any color ,whatever his position ,should have the right to go into any shop and buy what he wanted .After all, the money which I paid across the counter was exactly the same money as was paid by a European customer.
