Article: About this time every year, I get very nostalgic . Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors. It is hard for me to accept that many of my wonderful neighbors are growing old and won't be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever. The "comings and goings" of the younger generation of my street are now mostly "goings" as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world... Question: The biggest change on the writer's street is _ . Yes or no, is the answer "removing the hill to make way for residential development"?
No

Article: I love sleeping. It's something I'm good at. There's nothing better than nodding off on the sofa in front of the TV and when my head hits the pillow at night, I have no problem falling into a deep sleep within minutes. There is one place where I never nap and that's at work--but new research suggests I should! The idea of you and your colleagues heading off for a lie down in the afternoon may seem strange, but some companies such as Google and Facebook actually encourage it. Because it's thought that a power-nap makes them more refreshed and more focused, and this in turn makes them more productive. An Australian health writer called Victoria is a founder of a campaign called Nap Now which is trying to make sleeping at work more acceptable. She calls herself a " _ "! She says: "I think that our culture is a bit crazy not to accept it... It's time to end the common work principle which is all about working longer and harder." So should we all be taking a sleeping bag and pillow to work with us? A few years ago, research by the East of England Development Agency found 30% of people have their best ideas in bed compared to just 11% who have them at their desk. That suggests people are more creative when they are relaxed--and the agency has called for companies to put beds in the workplace. A nap in the afternoon is nothing new. In certain hot countries, such as Spain, a short rest or sleep in the afternoon-called a siesta-is perfectly normal. So maybe we should break from the traditional nine-to-five work culture and take up the siesta. The UK's Sleep Council claims the nine-to-five working day does not fit into the natural sleeping pattern of the human race and says that bosses need to introduce a more sleep-friendly working day. Question: What is the author's main purpose of writing the passage? Yes or no, is the answer "To call for the more sleep-friendly work culture."?
No

Article: During the next several weeks I went completely to the wolves. I took a tiny tent and set it up on the shore of bay. The big telescope was set up in the mouth of the tent in such a way that I could observe the wolves by day or night. Quite by accident I had pitched (set up) my tent within ten yards of one of the major paths used by the wolves. Shortly after I had taken up residence one of the wolves came back and discovered me and my tent, but he did not stop or hesitate in his pace. Later, one or more wolves used the track past my tent and never did they show the slightest interest in me. I felt uncomfortable at being so totally ignored. The next day I noticed a male wolf make boundary markers by passing water on the rounds of his family lands. Once I had become aware of the strong feeling of property rights which existed among the wolves, I decided to use this knowledge to make them at least recognize my existence. One evening, after they had gone off for their regular nightly hunt I staked out a property of my own, including a long section of the wolves' path. In order to ensure that my claim would not be overlooked, I made a property mark on stones, dumps of moss, and patches of vegetation with a lot of tea. Before the hunters came back, task was done, and I retired, somewhat exhausted, to observe results. A few minutes later, the leading male appeared. As usual he did not bother to glance at the tent, but when he reached the point where my property line intersected (cut across) the trail , he stopped as suddenly as if he had run into an invisible wall. Cautiously, he extended his nose and sniffed at one of my marked bushes. After a minute of hesitation he backed away a few yards and sat down. Then, he looked directly at the tent and at me. His glare seemed to become more fierce as I attempted to stare him down. The situation was becoming intolerable. To break the impasse I turned my back on the wolf. Then quickly and with an air of decision, he turned his attention away from me and began a... Question: What was the author's discovery? Yes or no, is the answer "Wolves were settled beasts and the possessors of an estate with definite boundaries."?
No
