Article: The soldiers had just moved to the desert, and as they had never been in such a place before, they had a lot to learn. As there were no trees or buildings in the desert, it was, of course, very hard to hide their trucks from enemy planes. The soldiers were, therefore, given training in camouflage. They were shown how to paint their trucks in irregular patterns with pale green, yellow, and brown paints, and then to cover them with nets to which they had tied small pieces of cloth. The driver of the biggest truck had a lot of trouble camouflaging it. He spent several hours painting it, preparing a net and searching for some heavy rocks with which to hold the net down. When it was all finished, he went for lunch. When he came back from his meal, he was surprised and worried to see that his camouflage was completely spoilt by the truck's shadow, which was growing longer and longer as the afternoon advanced. He stood looking at it, not knowing what to do. Soon an officer arrived, and he, too, saw the shadow, of course. "Well," he shouted to the poor driver, "What are you going to do about it? If an enemy plane comes over, the pilot will at once know that there is a truck there." "I know, sir," answered the soldier. "Well, don't just stand there doing nothing!" said the officer. "What shall I do, sir?" asked the poor driver. "Get your spade and throw some sand over the shadow, of course!" answered the officer. Question: What do you think of the ending of the story? Yes or no, is the answer "It is quite reasonable that the officer ordered the soldier to cover the shadow with sand."?
No

Article: People who daydream are often thought of in negative terms, such as being lazy or not doing what they should be doing. However, scientists who study the brain have learned many interesting things from studying the brains of daydreamers. Far from being a waste of time, recent research has shown that daydreaming is a healthy and useful activity for all of our brains. To study the brain, scientists use special devices that scan the brain and show pictures of which parts of the brain are active at certain times. When a person is daydreaming, the device will show a distinct pattern of activity in the brain called the "default" mode of thinking. In the default mode, the top or outside part of the brain is very active. Actually, several regions of the brain are interacting in this mode. Some scientists describe this mode as a time when the brain focuses on itself rather than focusing on the environment around the person. Typically, this occurs when a person is doing simple, undemanding work or performing routine actions that don't need much attention, like walking to school or cooking simple foods. People tend to daydream during such activities. The importance of daydreaming lies in developing both creative and social skills. When the mind is not engaged in dealing with one's immediate situation or problem, then it is free to wander. A time of wandering allows the mind to create things. New inventions may be imagined, or possible solutions to a problem can be planned. For example, solutions to problems in relationships with other people may spring to mind. In fact, most daydreams involve situations with others. Perhaps these are daydreams based on past memories, or daydreams of what might be in the future. In either case, daydreams help us develop the appropriate skills we can use in real interactions with others. As brain specialist Dr. Marcus Raichle of Washington University explains: "When you don't use a muscle, that muscle really isn't doing much. But when your brain is supposedly doing nothing and daydreaming,... Question: Which of the following is NOT involved in daydreaming? Yes or no, is the answer "One's immediate environment."?
No

Q: Article: Geena David knew she wanted to be a movie star when she was very young. She was not sure what gave her the idea, but she wanted to look like a movie star. "I have a lot of pictures from my childhood of me wearing sunglasses," she says. "I used to wear them to watch TV." Early movie actors started wearing sunglasses not because they looked good, but because their eyes hurt. The lights used on movie sets were extremely bright and could cause a painful problem known as "Klieg eyes". It was named after the Klieg brothers who invented the lights. Actors wore sunglasses to give their eyes a rest. But when movie stars began wearing their sunglasses in public, they quickly became a must. Eventually actors started wearing sunglasses in their movies as well as on the street. Audrey Hephburn wore ultra-cool Ray-Ban sunglasses in the 1961 movie, Breakfast at Tiffany's. As a result, Ray-Ban sunglasses started to appear more and more in the movies. In 1979, Ray-Ban "Wayfarers" were worn by Jake and Elwood in The Blue Brothers. Tom Cruise wore Ray-Ban "Aviator" sunglasses in the 1986 hit, Top Gun. Then in 1997, Will Smith and Tommy Lee Jones made Ray-Ban "Predator" sunglasses famous in Men in Black. Of course sunglasses aren't just a fashion statement. The main reason to wear sunglasses is to protect our eyes against UV radiation. UV radiation can damage our eyes, so people now choose their sunglasses carefully. But you don't have to give up style for safety. The choice of frames and lenses available these days is huge. So you can protect your eyes and still be the coolest person on the beach. Question: What is mainly discussed in this passage? Yes or no, is the answer "The sunglasses wearing."?
A: No

Article: I bought a Paul Smith shirt three months ago. For those who don't know, Paul Smith is an English designer brand. His shirts cost about 1,000 yuan and upwards. I paid 50 yuan for my colorful shirt from a street vendor in Beijing. Of course my shirt was a knockoff, a cheap copy of the brand. After a few washes, little balls formed on the surface of the thin material. Do I care? Not at all. You get what you pay for. I have to admit I hate shopping. _ I have other priorities. In You Are What You Wear, US writer Jennifer Baumgartner says people's clothes tell a story about their personality. She writes: "The clothes you choose to wear provide important information about you as a person: your approximate education level, your income, social status and even your level of self-esteem ." When I started work as an undercover crime reporter, I had to shop for jeans and a hoodie in order to fit in with a rough and ready social group. I bought the hoodie in a charity shop. My daughters were shocked. They thought I looked bad, but I knew my disguise was perfect. Elizabeth L. Cline thinks she knows best when it comes to cheap clothes in her book Overdressed: The Shockingly High Cost of Cheap Fashion. She expresses sadness that clothing has been turned into a good that is thrown away after being used once or twice. She looks down her nose at cheap fashion and longs for the good old days when department stores sold quality clothes at high prices. I don't agree. At least people now can choose what to wear without breaking the bank. Question: From the text we can infer that the author's disguise _ . Yes or no, is the answer "proved that clothes can't show a person's true personality"?
No
