Problem:OPTIONS:

Read the following article and answer the question. 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: What did Edeen say about recycled urine and the recycling system? Answer:
****
A: It takes a longer time on earth to make water from urine than in space.

Read the following article and answer the question. Article: The Golden Gate Bridge in San Francisco, California is one of the world's most beautiful bridges. It is also one of the most visited places in the world. Vehicles cross the bridge an average of 41 million times each year. More than 1,800 hundred million vehicles have used the bridge since it opened more than 70 years ago. The bridge was painted "International Orange" because that color went well with the natural surroundings. The color also is easier to see in the heavy fog that often covers the area. But the Golden Gate Bridge was not named for its orange color. It was named for the body of water that it crosses, the Golden Gate Strait. The Golden Gate Strait is the entrance to the San Francisco Bay from the Pacific Ocean. The Golden Gate Bridge links the city of San Francisco with Marin County,California. Planning for the bridge began in the 1920s when the area around San Francisco was growing. People living in the area needed another way to get to the city besides small ferries . Joseph Strauss was the chief engineer for the project. Work began in 1934. Mr.Strauss demanded the strongest safety protections in the history of bridge building. These included the first use of "hard hats" to protect the workers' heads and special glasses to protect their eyes. A special safety net was suspended under the bridge. This net saved the lives of 19 men during the construction. However, 11 other workers were killed when they fell from the bridge through the net. Still, this was a new safety record for the time. The Golden Gate Bridge opened in 1937. It extends 1,280 meters across the water. The total length is 2,737 meters. It was the largest suspension bridge in the world until 1964. That is when the Verrazano Narrows Bridge opened in New York City. Today, the Golden Gate Bridge is the ninth longest suspension bridge in the world. Question: What do we know about Joseph Strauss? Answer:
OPTIONS:
- He attached importance to the workers' safety.
- His safety measures were not of practical value.
- He built the first suspension bridge in the world.
- He demanded strong measures to ensure the safety of the bridge.

Answer: He attached importance to the workers' safety.

Q: Read the following article and answer the question. Article: My teacher held up a piece of broken glass and asked,"Who broke this window?" Thirty boys tried to think about not only what they had done,but also what our teacher may have found out.She seldom became angry,but she was this time. "Oh," I thought.I was the one who broke the window.It was caused by a naughty throw of a baseball.If I admitted guilt,I would be in a lot of trouble.How would I be able to pay for a big window like that? I didn't even get an allowance. "My father is going to have a fit,"I thought.I didn't want to raise my hand,but some force much stronger than I was pulled it skyward.I told the truth. "I did it." It was hard enough to say what I had. My teacher took down a book from one of our library shelves and I had never known my teacher to strike a student,but I feared she was going to start with me. "I know how you like birds," she said as she stood looking down at my guilt-ridden face."Here is that field guide about birds that you are constantly checking out. It is yours now.It's time we got a new one for the school anyway.You will not be punished as long as you remember that I am not rewarding you for your misdeed, I am rewarding you for your truthfulness." I couldn't believe it! I wasn't being punished and I was getting my own bird field guide--the very one that I had been saving up money to buy. All that remains of that day is my memory and the lesson my teacher taught me. That lesson stays with me every day and it will echo forever. Question: If the boy admitted guilt, he thought he would NOT _ . Answer:
