Question: Article: You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are _ . Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight. When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open. Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second. Question: This article is probably from _ . Yes or no, is the answer "a science magazine"?

Question: Article: With fifteen years prefix = st1 /Britainand other nations should be well on with the building of huge industrial complexes for the recycling of waste . The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful . Even the most dangerous and unpleasant wastes would provide energy if nothing else . The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out . The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city . This plant would recycle not only metal such as steel , lead and copper , but also paper and rubber as well . Another new project is being set up to discover the best ways of sorting and separating the rubbish . When this project is complete , the rubbish will be processed like this : First , it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed ; then it will pass through a powerful fan to separate the lightest elements from the heavy solids ; after that founders and rollers will break up everything that can be broken . Finally , the rubbish will pass under magnets , which will remove the bits of iron and steel ; the rubber and plastic will then be sorted out in the final stage . The first full-scale giant recycling plants are perhaps fifteen years away . Indeed , with the growing cost of transporting rubbish to more distant dumps , some big cities will be forced to build their own recycling plants before long . Question: The first full-scale huge recycling plants_. Yes or no, is the answer "will probably be in operation in fifteen years"?
Answer: No

Question: Article: Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free! It's "no". What do you ask? We'll say it again: "No". Sweet and simple "no". Say "no" at your office and see how quickly that pile of work on your desk disappears. "Saying 'no' to others means you are saying 'yes' to yourself, " said Leslie Charles, a professional speaker from East Lansing, Michigan. "Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can't say 'no'." Susie Watson, a famous writer, said people who always say "yes" need to say "no" without guilt or fear of punishment. "I would rather have someone give me a loving 'no' than an obligated 'yes', " she said. Susie Watson says she feels "no" obligation to give an explanation when she says "no" either socially or professionally. Does she feel guilty about it? "Not at all, " said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Conneticut. "Most people are afraid of saying 'no'... My advice is to say 'yes' only if you don't mean 'no'." Watson said "no" is the most effective weapon against wasting time. "Every year there are more demands on your time... Other people are happy to use up your time, " Watson said. Time saving appears to be "no's" greatest friend. "No" can be your new friend, a powerful tool to take back your life. "No" may even take you further in the business world than "yes". "No" is power and strength. "No" now seems completely correct. "Saying 'no' isn't easy. But finally it's greatly liberating," Charles said. But, he added, a "no" project needs to be worked on every day because it is hard to change long-term habit. But, he also warns: "Don't go to extremes. Don't find yourself saying 'no' to everything. In return you should learn to hear 'no'." Question: The sentence "Saying 'yes' to yourself" means _ . Yes or no, is the answer "you can deal with your business as you have planned"?
Answer:
Yes
