Article: Have you ever noticed what happens to an idea once you express it ? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing. By putting thoughts into words, you are telling yourself the logic behind what you think, feel,or only partly understand. Often,explaining a thought is the process of understanding.In other words, you increase your brain power by exercising your"explain power". Another benefit of writing is that it helps you remember. Many,if not most,highly productive people are always taking notes.You can try keeping it all in your head,but if you keep a journal of your ideas the next time you're working on a big project, you'11 probably have more success. Want to understand a topic? Write a book about it.That's an extreme example, but if you are learning something new,write a letter to a friend about it,and you will understand it better. Want to invent something? Write an explanation of the problem---why you want to solve it,and why it is worth solving, and you're half-way there. Writers don't always write because they clearly understand something beforehand. Often,they write about something because they want to understand it. You can do the same. Writing will help bring you to all understanding. Give it a try. Question: According to the passage,writing can help you a lot EXCEPT _ . Yes or no, is the answer "to develop your interest in study"?
(Answer)
Yes

Article: The next generation telephone is called Superphone or personal Communication Network (PCN). Your superphone goes wherever you go, in your pocket. You can use it in the street, in an aeroplane, a boat, or a taxi; you can call from anywhere on the globe to anywhere else. Calls travel at the speed of light, via satellites using ultraviolet, high-frequency wave bands and each communication is automatically billed to your account. This new phone is the size and shape of a billfold . You unfold it to use it., making it long enough to reach from your ear to your mouth. There is a miniaturized touch pad, on which to enter the number you are calling. There is also a tiny liquid crystal screen on which you can read weather, news or financial reports. These news items are constantly updated by the company that sells the service. Letter keys on the touch pad also allow you to use this electronic marvel as a computer or word processor. You can plug it into your large home or office computer in order to transfer any data that you feed in during a business trip. The PCN also stores any useful information of your own that you might need as you travel, such as the names, addresses and phone numbers of several hundred people, important meetings, flight details and so on. When you need information, you simply call it up on the screen. You can even use your PCN to activate electronically controlled equipment at home. For example, you could switch your oven on or off, start the sprinkler system in your garden during a dry spell, get your video recorder to record a show on television, turn off the central heating, and so on. All of this from thousands of miles away, perhaps from the back of a camel in the desert. Prototypes are already being trialed. In spite of the complex technology, they will be cheap because of the enormous sales that will be made. Question: The next generation telephone doesn't own the function of _ Yes or no, is the answer "a billfold"?

No

Article: Cao Min couldn't believe she was experiencing exactly what she had seen years ago in the film "Titanic". Cao and her two children from Anhui Province were traveling on board the "Liaoludu 7" on February 22. They were among the first people on the ship who were rescued by lifeboats. Cao's one-year-old son was the youngest passenger on board. The "Liaoludu 7" was traveling in the Bohai Straits from Lvshun in Liaoning Province to the port city of Longkou in Shandong Province. It suddenly lost its power at 2:30 pm and tilted on its side. With 81 people on board, the ferry began to sink. "I was so scared that my legs couldn't move forward. They kept shaking even when I was asked to jump onto a lifeboat," Cao recalled. Upon receiving the mayday appeal , China Marine Search and Rescue Centre immediately informed the State Council. The center sent eight lifeboats to the fishing boats. After more than four hours of fighting strong winds and freezing ocean water, the passengers were recovered. All but four survived. These four died after spending too long time in the freezing waters, according to a spokesperson for the Beijing-based center. Question: According to the passage, _ passengers on board were still alive. Yes or no, is the answer "seventy-seven"?
