Read the article and select the best answer. 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 passage may be   _  . Options: A: an interview B: an argument C: a talk show program D: a science report

Read the article and select the best answer. Article: Although there are many ways in which people communicate through speech, public speaking has probably received more study and attracted more attention than any other. Politicians winning an election, salespeople presenting products and etc. All depend upon this form of public communication. Even people who do not make speaking a part of their daily work are often asked to make public speeches: students at graduation, for instance, or members of churches, clubs or other organizations. Nearly everyone speaks in public at some time or other, and those who perform the task well often become leaders.     There are many reasons for speaking in public. A public speaker may hope to teach an audience about new ideas, or provide information about some topic. Creating a good feeling or entertaining an audience may be another purpose.  Public speakers, however, most often seek to persuade an audience to accept new opinions, to take certain actions, or to see the world in a new way.     Public speakers usually know well in advance when they are scheduled to make a speech. Consequently, they are able to prepare their message before they deliver it.  Sometimes, though, speakers must deliver the message unprepared, or off the cuff, such as when they are asked to speak at a wedding reception or to participate in an interview.     When they do not have to speak unprepared, most speakers write their own speeches. Politicians and business managers sometimes employ professional writers who prepare their speeches for them. These professional writers may work alone or in small teams. Although the speaker may have some ideas into the contents of the speech, the writers sometimes have a great influence over the opinions expressed by their employers. Regardless of how a speech is prepared, the person who delivers it is given credit for its effect upon its hearers. Question: Which of the following is rarely the purpose of public    speaking? Options: A: To influence people's ideas and behaviour. B: To persuade the audience to accept an idea. C: To enjoy the satisfaction from one's own speech. D: To develop public interest.
