Q: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
A: B
Rationale: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.
Q: Article: Last fall,beekeepers from states with warm climates began to report a sudden loss of honey bees.Losses were reported in twentyfour states and spread to Canada.Today,some beekeepers say thirty percent to ninety percent of their honey bees are gone.Food price could go up as a result.And some beekeeping businesses have failed. Many kinds of plants,trees and grasses need bees to pollinate them.Bees gather nectar from flowers during this process.The liquid gives them food and material to make honey.As the bees land on flowers,their bodies pick up and drop off particles of pollen .Most flowering plants need pollination to reproduce. Honey bees can die during the winter.But few dead bees have been found this time.Instead,the bees seem to have disappeared.Experts call the condition "colony collapse disorder". Agriculture Department official Caird Rexroad said the colony collapse disorder threatens about fifteen billion dollars worth of the country's farm economy.Mr.Rexroad commented at a hearing of a House of Representatives agriculture subcommittee. Mr.Rexroad said the cause of the sudden loss of bees was not clear.The number of honey bees had already fallen before the colony collapse disorder began. Experts say the varroa mite is at least partly responsible for the earlier decrease in honey bees.The mite is a tiny creature that feeds on honey bees.It may play a part in colony collapse disorder by carrying bee viruses.Or the problem may be caused by other disease and weather conditions. Diana CoxFoster of Pennsylvania State University is part of the scientific group.Ms.CoxFoster says the nation needs honey bees that can defend themselves better against disease and insects.The recent mapping of most of the honey bees' genes offers the hope of a stronger honey bee some day.
Question: Some people have failed in beekeeping businesses because _ .
Options: (A) they want to make more money by doing something else (B) the climates were too warm to raise bees last fall (C) too many bees have disappeared for no reason (D) more and more people are beginning to raise bees
