Article: Some colors people see late at night could cause signs of clinical depression . That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression. Doctors use the word "clinical depression" to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide. In the new study, American investigators designed an experiment that exposed hamsters to different colors. The researchers chose hamsters because they are nocturnal, which means they sleep during the day and are active at night. The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water. Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. "What we saw is that these animals didn't show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim red light, they did not." Randy Nelson notes that photosensitive cells in the eyes have little to do with eyesight. He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle. He says there's a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness. Question: Researchers use hamsters in the experiment because _ . Yes or no, is the answer "they are active at night and sleep during the day"?
No

Article: Do you wake up in the morning dreading the moment that your feet have to hit the floor for you to get ready for work? If that's the case, join most of Americans. Very few people wake up to that annoying alarm clock and spring out of bed excited about having to go to work. As if that were not enough, most of us have to fight traffic getting there, usually an hour's drive. Then, when we get to work, we have to fight with unruly co-workers or a nagging boss. And to make matters worse, you have to fight the same traffic going in the opposite direction just to get back home. Making dinner, fixing plates, eating and then straightening up afterwards is a job within itself. If that sounds like your life, you probably have a J-O-B. you know what J-O-B stands for? Just Over Broke, that's what! With a job, most Americans are living paycheck-to-paycheck and hating every minute of it. I know because I was doing the same thing: trading time for money. And, I came to a conclusion that it stinks ! Big time! Looking around at my co-workers, friends and relatives, I saw that they were all doing the same thing I was doing. They were complaining about the same things I was complaining about : not having enough time or money. And, I decided that I wanted to do .[:** So, I started a home-based business. There are several to choose from. The extra income has done so much for our family. We can vacation more. We have been able to give more. And, we've even been able to do something calling save! It's been amazing. Therefore, if you're sick and tired of being sick and tired, it's time you make a change, too. The definition of insanity is doing the same thing over and over and expecting different results. I know you aren't stupid. If you continue to do what everyone else is doing: trading time for money, you're going to keep getting what everyone else is getting: being broke and not having the time to do what is really important to you. Do your due diligence. Find a home-based business that works well for you. Go to work, and live... Question: What does "something different" in Paragraph 4 refer to? Yes or no, is the answer "To set up a business at home."?
No

Article: I have nothing to say about whether or not "A Day Without Immigrants " had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others. Regardless of how you feel about the event, one conclusion is obvious. Using the theme of "A Day Without" as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public consciousness about other issues that affect daily life in America. Here are my top three examples: "A Day Without Speeding." How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge. "A Day Without Losing Your Temper." A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but bursting into anger usually has nothing to do with the approach to the heart of the matter. "A Day Without Having All The Answers." I would like to get a break from hearing anyone speak the phrase, "Here's what you're doing wrong." Right now the US is packed with citizens who believe they can point out the cause of every single problem in existence and then solve it in a moment. I believe they need to be quiet sometimes and use their ears instead of their voices. I wonder how would average Americans react to such a national pause? Would it be a day of reaction against anger, or joyful celebrations? Question: The author uses his "top three examples" to _ . Yes or no, is the answer "show public consciousness of some subjects could be raised"?
No
