Article: California sea lions are the fastest of all the sea lions, reaching speeds of up to 40 kilometers an hour when swimming. Males are much larger than females, measuring 2 to 2.5 meters and weighing 200 to 453 kilograms. Females only measure 1.5 to 2 meters and weigh 50 to 113 kilograms. They can also move fairly well while on land. California sea lions can be found living along the Pacific coast of North America. They prefer to live in waters near rocky and sandy shores. On land, they often gather in large groups as many as 1,000 of them. While at sea, they travel in much smaller groups of around 10 or more. They communicate with one another through a series of sounds. Their diet consists of a wide variety of fish and other sea animals. They are able to hold their breath for up to 10 minutes by slowing down their heart rate, allowing them to hunt for their prey for a longer period of time. They have been known to continuously hunt for up to 30 hours at a time, with their eyesight and hearing playing an important part in finding their food. Being so large, they do not have that many natural predators that they need to be on the lookout for. Eleven months after getting pregnant, the female will give birth to one baby on land. If the baby can survive long enough, they can live to be 20 to 25 years old. California sea lions are not listed as an endangered species. This is largely because of laws such as the US Marine Mammal Protection Act of 1972. Hopefully such acts will continue to show results. Question: What do we know about California sea lions? Yes or no, is the answer "Males are much larger than females."?
No

Article: We've heard about radiation from the damaged nuclear reactors in Japan reaching American shores. Experts say so far there is no reason to worry, and point out that we meet radiation every day. Where and how? NPR's Renee Montagne posed that question to Peter Caracappa, a radiation safety officer and professor of nuclear engineering. MONTAGNE: How many things emit radiation? Dr CARACAPPA: Well, radiation and radioactive material is a part of nature. So everything that's living has some amount of radiation coming from it--a very small amout. Plus there's radiation in the ground and the air. So the extremes are uranium in the soil to bananas? Yes. By the way, why do bananas have radiation? Bananas have a lot of potassium . And a small amount of potassium naturally is called potassium 40, which is radioactive What's the difference between radiation that's harmful and not harmful? Well, the term radiation can apply to a lot of different things. But the harmful radiation is ionizing radiation. It has enough energy that it can make chemical changes in material. We could get ionizing radiation from an X-ray, for example. It's the kind of radiation that causes cancer. The broader definition of radiation includes a lot of things that we call non-ionizing radiation. That includes everything like radio waves and visible light and your microwave. So what then is the largest contributor of ionizing radiation? For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon , which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes like basements. Would it be fair to say that most people do not need to worry about the danger of being exposed to radiation? I would say that the everyday exposure to radioation that we meet contributes an extremely tiny risk to our life or to our health compared to all of the other risks that we meet in our day-to-day life. Question: The purpose of writing this passage is to _ . Yes or no, is the answer "expect people not to fear everyday radiation"?
No

Q: Article: Our body clock,or natural body rhythm,influences our energy and alertness.Paying attention to it can help us choose the suitable time of day when we best perform specific tasks. The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society. But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor. When the body clock can synchronize(......)the rhythms of its natural processes,it "gives us an advantage in daily life",says Key. According to him,when it comes to cognitive work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve. However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted between noon and 4 pm. Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap. Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning. When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering. Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans. Question: According to Steve Key,which of the following is NOT true? Yes or no, is the answer "When it comes to cognitive work,most people perform best in the late morning."?
A: 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 author may agree that _ Yes or no, is the answer "the new phone has excellent prospects in market."?
(Answer)
Yes
