Question: Article: Why do our eyes open wide when we feel fear? And why do our eyes become narrow when we express disgust ? According to a new research, it has something to do with survival. In a recently published paper, researchers concluded that expressions of fear and disgust changed the way human eyes gather and focus light. They argued that these changes were the result of evolutionary development and were intended to help humans survive, or at least discover, very different dangers. In order to test their hypothesis ,researchers examined two dozen volunteer college students with standard eye-exam equipment, and asked them to show expressions of fear and dislike. It was found that when the students widened their eyes, more light was admitted and their field of vision was expanded. When they wrinkled their noses in disgust, their eyes narrowed. This had the effect of blocking out more light but focusing on a specific point. Although some scientists have admitted that emotional expressions are intended primarily to communicate information, expressions of fear and disgust seem to perform different visual functions. "Eye widening may help to find a potential danger that requires much attention. And this would agree with the hypothesized function of fear," said researchers. "On the other hand, eye narrowing may help to distinguish and avoid different kinds of dangers, such as disease carriers and dirty foods. And this would agree with the hypothesized function of disgust." These findings supported naturalist Charles Darwin's view that expressions are not necessarily for communication and are not arbitrary ."If our expressions were arbitrary, they would show little cross-cultural relationship." researchers said. "But actually, our expressions probably have some universal functional principles."
Question: What is the hypothesis of the research in this text?
Options: (A) Changes of human eyes lead to different emotional expressions. (B) Evolutionary development helps humans survive different dangers. (C) Emotional expressions affect how human eyes collect or focus light. (D) Evolutionary development causes people to express different feelings.

Answer: C

Question: 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

Answer: C

Question: Article: If your family is thinking of getting a pet, consider adopting from an animal shelter. Animal shelters are full of dogs, cats, rabbits, and more animals, all in need of loving homes. Some may come with emotional or behavioral issues, but most are happy, healthy, and ready for a loving home. Here are some tips for you to find great animals. Make some decision. Think about what you want in a pet and remember that all pets have different personalities. Cats tend to be more independent and need less affection, but kittens need lots of attention. Cats don't need to be walked, but you need to clip their nails and play with them. Dogs need to be walked at the very least twice a day. However, they are usually great companions and love to spend time with their family. Visit the shelter. Set aside at least a few hours to visit shelters in your area--remember that you may need to visit more than one visit. Try to bring along everyone who will be living with a new pet. Ask the shelter staff lots of questions. And never adopt an animal because you feel sorry for it--be patient so you find a pet who is truly a good match for your family. Get everything ready. Buy all necessary supplies and food well before the animal comes home. Make sure that the entire household is in agreement about rules and responsibilities--will the dog be allowed on the couch? Who will clean the litter box? Put it in writing before the pet arrives. Bring your new friend home! You'll probably be excited when your new pet arrives, but be sure to give them space and time to get adjusted to a new home and a new family. The pet may act differently once they leave the shelter. Interact with your pet a lot and get them used to a routine, and soon you'll be one big happy family !
