Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Doctors sometimes use 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 disorder. 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. 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 night-time darkness, those getting dim light at night lost their strong preference for sweet drinks. "A sign that 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 night-time darkness. All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report. The scientists could also _ 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 night-time light and mood disorders are important but can not easily detect molecular underpinnings  as animal studies can, says George Brainard of Thomas Jefferson University. The new work,... Options: A changed their preferences B escaped from the water more eagerly C remained active as before D showed less interest in their favorites Answer: D showed less interest in their favorites Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.    A pedestrian is killed in a traffic accident in the USA every 110 minutes;one is injured every nine minutes, according to official data. Crosswalk can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared with 21% of those younger than 70, according to the Insurance Institute for Highway Safety.    The Federal Highway Administration(FHWA)advises that next year states increase by nearly 15% the amount of time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears .    FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of driving.    Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006. But among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration (NHTSA) says . Options: A Among 100 pedestrian deaths there were 21 people younger than 70. B Old people are more likely to meet with accidents in crosswalks. C Traffic accidents killed more old people than young people. D About seven traffic accidents happened per hour. Answer: B Old people are more likely to meet with accidents in crosswalks. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Our senses aren't just delivering a strict view of what's going on in the world; they're affected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten. Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brain's high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten. For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they'd seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it. Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the... Options: A 42 participants are too small a number for a serious investigation. B An experiment with hungry and non-hungry participants is not reliable. C Our thinking processes are independent of our senses. D Humans can perceive what they need without involving high-level thinking processes Answer: D Humans can perceive what they need without involving high-level thinking processes Question:
