Read the following article and select the best answer. Article: Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine , sweat and water got from air. They said "cheers," clicked drinking bags and toasted NASA workers on the ground. The urine recycling system is needed for astronaut stations on the moon and Mars. It also will have NASA money because it won't have to ship up as much water to the station by space shuttles or cargo rockets. Besides, it's important as the space station is about to expand from three people living on board to six. The recycling system had been brought up to the space station last November by space shuttles Endeavour, but it couldn't be used until samples were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centres that worked on the system. "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said before taking a small mouthful. "The taste is worth trying." The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor is collected. The rest of the urine is thrown away. Then the water vapor is mixed with water from air, and then it goes through filters . When six crew members are aboard it can make about six gallons from urine in about six hours. "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap," said Marybeth Edeen, the space station's national lab manager. The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami. Question: From Para. 5 we can know _ . - the theory behind the recycling system - the effect of the recycling system - the process of recycling urine - an opinion on recycling urine
**Answer**
the process of recycling urine

Read the following article and select the best answer. Article: Why don't so many Americans accept the theory of evolution? A 2001 Gallup Poll found that 45 percent of Americans agree with the statement "God created the human being pretty much in their present form at one time within the last 10,000 years or so ", while 37 percent preferred a mixed belief that "Human beings have developed over millions of years from less advanced forms of life, but God guided this process", and only 12percent accepted the standard scientific theory that "Human being have developed over millions of years from less advanced forms of life, but God had no part in this process". There are at least four reasons to make people resistant to accepting evolution. 1. The warfare model of science and religion. The belief that there is a war between science and religion where one is right and the other is wrong, and that one must choose one over the other. 2. The belief that evolution is a threat to specific religious tenets . Many people attempt to use science to prove certain religious tenets, but when they do not appear to fit, the science is rejected. 3. Misunderstanding of evolutionary theory. A significant problem is that most people know so little about the theory. In the 2001 Gallup Poll, for example, a quarter of the people surveyed said they didn't know enough to say whether they accepted evolution or not, and only 34 percent considered themselves to be "very informed " about the theory. 4. The fear that evolution degrades our humanity. Darwin revealed us to be "mere animals", subject to the same natural laws and historical forces as all other animals. Believers should embrace science, especially evolutionary theory, for what it has done to uncover the magnificence of the divinity in a depth never dreamed by our ancient ancestors. We have learned a lot in 4,000 years, and that knowledge should never be denied. Instead, science should be welcomed by all who cherish human understanding and wisdom. Question: What can we learn form the passage about evolutionary theory? - Whether evolutionary theory is science is a question. - It has explained the brilliance of the divinity better than before. - It must make religion disappear and they can't exist at the same time. - Darwin made little contribution to the theory.
**Answer**
It has explained the brilliance of the divinity better than before.

Read the following article and select the best answer. Article: I might be letting my young son watch too much television. I am certainly watching too much many of his programs. They can really be puzzling as they force you to _ . For example, when Franklin (the turtle) wanted a pet, his parents did not want it to be a frog. They felt that frogs belong in a pond. Isn't that where turtles belong? And why is it that Little Bear's animal friends can all talk and behave like people, but his friend Emily has a dog that can only bark and fetch? Tell me that isn't a mystery! Dog lovers can be reassured (less worried or frightened) by Kipper and his friends. These dogs are very human. However, the only time they wear clothes is when they put on bathing suits to go swimming. I am confused! Speaking of dogs, could Pluto ever be Goofy's pet? I don't get it! What did the great Mr. Disney have in mind? And this is unfair! The other day we watched a very nice little pig setting up a picnic. One of the foods was a big ham. Could it have been a soybeam ham? Is there such a thing? I hope so! Another thing that really bothers me: what if Elmo(one of my son's favorite cartoon stars) isn't real? He can't be a mere puppet ! He's got a better attitude than most people. I just keep wondering. I think we will turn off the TV and go out for a walk. Maybe we will run into that mouse who dresses well but certainly doesn't speak as clearly as the average bear. Question: The author thinks it is "unfair" when _ . - a pig has a picnic because pigs are dirty animals - a pig eats soy beans because soy beans give pigs gas - a pig eats ham because ham is too expensive for farmer animals - a pig eats ham because ham is made from pigs.
**Answer**
a pig eats ham because ham is made from pigs.
