I'm taking a test and have to guess the right answer to the question after the article. Article: Doctors sometimes prescribe light therapy to treat a form of depression in people who get too little morning sun. But too much light at other times may actually cause such mood disorders. Long-lasting exposure to light at night brings depression, a new study finds, at least in animals. The new data confirm observations from studies of people who work night shifts, says Richard Stevens of the University of Connecticut Health Center. Mood disorders join a growing list of problems, including cancer, obesity and diabetes--that can occur when light throws life out of balance by disturbing the biological clock and its timing of daily rhythms. www.ks5u.com In the new study, Tracy Bedrosian and Randy Nelson of Ohio State University exposed mice to normal light and dark cycles for four weeks. For the next four weeks, half of the mice remained on this schedule, and the rest received continuous dim light throughout their night. Compared with mice exposed to normal nighttime darkness, those getting dim light at night lost their strong preference for sweet drinks, "a sign they no longer get pleasure out of activities they once enjoyed, " Bedrosian says. In a second test, mice were clocked on how long they actively tried to escape a pool of water. Those exposed to night lights stopped struggling and just floated in the water, a sign of "behavioral despair",10 times as long as the mice that had experienced normal nighttime darkness. All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report. The scientists also could quash the behavioral symptoms by injecting the brains of animals with a drug that prohibits the activity of certain molecules linked with human depression. This finding further suggests that light at night may cause something related to depression. Human studies linking nighttime light and mood disorders are important but can't easily detect molecular underpinnings as animal studies can,says George Brainard of Thomas Jefferson... Question: After being exposed to continuous nighttime light, the mice _ . Options: A: changed their preferences B: escaped from the water more eagerly C: showed less interest in their favorites D: remained active as before

I'm taking a test and have to guess the right answer to the question after the article. Article: Chinese media and Internet users on Monday condemned lack of morals in society after a toddler was struck twice -by two different vans-and left bleeding on the road as more than a dozen bystanders did nothing to help the seriously injured girl. The incident, captured by a surveillance camera and broadcast by Southern Television Guangdong (TVS),showed the two-year-old girl was knocked down and run over by a white van on a narrow market street on the afternoon of Oct.13,in Foshan City of Guangdong Province. The driver fled the scene of the accident,leaving the girl to bleed on the sidewalk.Over the next six minutes,more than a dozen people walked by the girl,yet not one individual did anything to help her.The girl was then hit a second time by another van before an elderly trash collector came to her aid and brought the attention of the girl's mother,according to the video and eyewitnesses. Doctors said that the girl,who was put on life support after being hospitalized,remains in a deep coma.The girl's parents,who are migrants living in the city,are now with her. Police said the drivers of both vehicles have been arrested.However,the apathy of the bystanders shown in the video has shocked the public,as Internet forums have seethed with anger, and people are questioning the morality of society. High moral standards were once triumphed as national pride in China where individuals known for selflessly helping others were adored by the public. But in recent years,the perception of a decline of morals has become a hot topic as profit and materialism are perceived to be affecting society's values. On Sept.2 an 88-year-old man in central China collapsed,his face striking the pavement.Yet,no one came to his aid,and he ended up choking to death on the blood from his nose. Some have linked the absence of good Samaritans to a previous case in which a man trying to help an elderly woman who fell was accused of harming her. A strong chorus of opinion on the Internet says laws should exempt Samaritans from liability ,yet... Question: Which of the following is TRUE about this passage? Options: A: Nobody helped the girl who was struck twice by two different vans. B: The toddler died immediately after she was hit a second time. C: High moral standards were once regarded as national pride in China. D: Journalists from TVS captured the incident by using a camera.
