Article: It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor.On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, "Graduation will be one of the happiest and one of the saddest time of your life." At my inquiry, he answered, "Because the students you have gotten to know have to leave." As years went by, my previous confusion about my colleague's words no longer existed.When I came across naughty students, I have had to rethink why I chose to be a teacher.It obviously isn't the money.Once a former computer science student of mine called me, asking me if I wanted to have a change.He was working at Nintendo Corporation.His salary was higher than my current one, though I have more education and have worked for over a decade.With my programming skills, he said he could get me hired.I thanked him, but declined his kind offer. A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework.She thanked me for being her teacher and said the things she had learned in my class--not about math, but about life--would be things she would remember long after the math skills had faded away.As I finished reading, I remembered why I had become a teacher. Now, on this sunny graduation day, as I again observed the sea of _ , I did so with renewed dedication and a deeper sense of satisfaction--I will always be grateful that I am a teacher. Question: The author wrote this passage to _ . Yes or no, is the answer "express his devotion to being a teacher"?

No

Article: Beavers are a very unique species in the world of nature and wildlife----they are architects. Their dams are fine examples of engineering. A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter. From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has "walls", one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses. Trees are essential to beavers. They eat the bark on the upper branches. But they must first _ the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree. The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood. Question: This text is mainly about _ . Yes or no, is the answer "the beaver's engineering skills"?
**Answer**
No

Article: LONDON --- A British judge on Thursday sentenced a businessman who sold fake bomb detectors to 10 years in prison, saying the man hadn't cared about potentially deadly consequences. It is believed that James McCormick got about $77.8 million from the sales of his detectors which were based on a kind of golf ball finder to countries including Iraq, Belgium and Saudi Arabia. McCormick, 57, was convicted of cheats last month and sentenced Thursday at the Old Bailey court in London. "Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people," Judge Richard Hone told McCormick. "you have neither regret, nor shame, nor any sense of guilt." The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they "lacked any grounding in science" and were of no use. McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand. "I never had any bad results from customers," he said. ks5u Question: According to the judge, what McCormick had done _ . Yes or no, is the answer "lowered people's guard against danger"?
**Answer**
Yes
