Q: Article: According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year.Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom.An experiment under way off the coast of Norway, however, could help put them anywhere. The project, called Hywind, is the world's first large-scale deepwater wind turbine .Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents totally new technology.The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind's creator, the Norwegian company StatoilHydro, has developed recently.The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywind's stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power.If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September. To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean.To make that turbine heavier, the whole spar's center of gravity must be moved much closer to the ocean's surface.To do that, the company plans to design a new kind of wind turbine, one whose gearbox sits at sea level rather than behind the blades. Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large.Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted.Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection.If the technology catches on, it will open up vast areas of the planet's surface to one of the best low-carbon power sources available.
Question: The Hywind project uses totally new technology to ensure the stability of _ .
Options: (A) the cables which tie the spar to the ocean floor (B) the spar which is floating in deep-sea water (C) the blades driven by strong and steady sea wind (D) the stones filled in the spar below the sea surface
Asnwer: C

A: No

Q: Article: Amanda Clement grew up in Hudson, South Dakota. Baseball was always her favorite sport. Once in a while her brother Hank and his friends would let her play first base in their games. More often, however, they asked her to umpire for them, because they knew her calls would be fair and there would be no arguing. One day in 1904, Amanda and her mother traveled to Hawarden, Iowa, to watch Hank play for the home team against Hawarden. When they arrived at the ball field, two local teams were waiting to play a preliminary game. The umpire hadn't arrived, so Hank argued that the teams should let his sister serve as umpire. The players finally agreed. Amanda, then sixteen and standing five feet, ten inches tall, made perfect calls. She was so good that players for the main game asked her to umpire for them and even offered to pay her. Thus, at sixteen, Amanda Clement became the first paid female baseball umpire of all time. She is honored in the Baseball Hall of Fame in Cooperstown, New York.
Question: Why did Hank and his friends often ask Amanda to umpire for them?
Options: (A) Because she called them brothers. (B) Because they wanted to make her happy. (C) Because no one else wanted to do it for them. (D) Because she knew the rules well and was fair.
Asnwer: D

A: Yes

Q: Article: How can we measure animals' emotions? A new study of animal's emotions suggests that, as in humans, emotions can tell animals about how dangerous their world is, and guide the choices that they make. The article of the study by Bristol University's professor Mike Mendl was published online. An animal living in an environment where it is often threatened by predators will develop a negative emotion or "mood", such as anxiety. However, one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state. The researchers say that these emotional states not only show the animal's experiences, but also help it decide how to make choices, especially in unclear situations. This could have good or bad results. An animal in a negative mood state will make a safety-first with a "pessimistic" response to an unclear event. For example, it considers a noise in the grass as a signal of the predator. At the same time, an animal in a positive mood state will benefit from a more "optimistic" response. It considers the noise as a signal of prey . Professor Mike Mendl, head of the Animal Welfare and Behavior Research Group at Bristol University's School of Clinical Veterinary Science said, " We can use "optimistic" or "pessimistic"decision-making as a symbol of an animal's emotional state. Recent studies by our group and others suggest that this is a _ new approach to studying a variety of animal species." "Public interest in animal welfare remains high, with widespread concern about the way in which animals are treated, used and included in society. To understand how animals should be treated, we need to better understand their emotional lives," Mike Mendl said. The researchers believe Mike Mendl's study can help them to better understand and assess an animal's emotions.
Question: When an animal is in a negative mood state, _ .
Options: (A) its response to an unclear event is pessimistic (B) it will pay little attention to an unclear event (C) it is easy for it to make right decisions (D) it has more opportunities to get food
Asnwer: A

A:
Yes
