Read the following article and select the best answer. 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: What can help people who work late at night to avoid being depressed? - Not being exposed to dim red light when using computers. - Equipping their computer screens to put it more in the reddish light. - Living or working in low levels of light overnight. - Going to see doctors of clinical depression regularly for help.
**Answer**
Equipping their computer screens to put it more in the reddish light.

Read the following article and select the best answer. Article: It was the small hours of the morning when we reached London Airport. I had cabled London from Amsterdam, and there was a hired car to meet, but there was one more unfortunate happening before I reached my flat. In all my travels I have never, but for that once, been required by the British customs to open a single bag or to do more than state that I carried no goods liable to duty. It was, of course, my fault; the extreme tiredness and nervous tension of the journey had destroyed my diplomacy. I was, for whichever reason, so tired that I could hardly stand, and to the question, "have you read this?" I replied with extreme foolishness, "yes, hundreds of times." "And you have nothing to declare?" "Nothing." "How long have you been out of this country?" "About three months." "And during that time you have acquired nothing?" "Nothing but what is on the list I have given you." He seemed momentarily at a loss, but then he attacked. The attack, when it came, was utterly unexpected. "Where did you get that watch?" I could have kicked myself. Two days before, when playing water games with a friend in the bath, I had forgotten to take off my ROLEX OYSTER, and it had, not unnaturally, stopped. I had gone into the market and bought, for twelve shillings and six pence, an ugly time piece that made a strange noise. It had stopped twice, without any reason, during the journey. I explained, but I had already lost face. I produced my own watch from a pocket, and added that I should be grateful if he would confiscate the replacement. "It is not a question of confiscation," he said, "there is a fine for failing to declare dutiable goods. And now may I please examine that Rolex?" It took another quarter of an hour to persuade him that the Rolex was not contraband . Just when I let out a sigh of relief, he began to search my luggage! Question: After reading the story we can infer that the writer _ . - knew little about the customs regulations - must have spent a long time at the customs and have been let go without any punishment - must have been fined because of carrying many contraband goods - must have failed in catching the hired car
**Answer**
must have spent a long time at the customs and have been let go without any punishment
