Article: Different kinds of soil conservation methods are used by farmers to protect their land from damage by farming and the forces of nature. One important form of soil conservation is the use of windbreaks. Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant them in lines around their fields. Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat. There have been studies done on windbreaks in parts of West Africa, for example. They found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection. However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions will lift soil into the air where it will be blown away. For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line. There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for windbreaks.
Question: What is a windbreak according to the passage?
Options: (A) A windbreak is a concrete wall to prevent the strong winds. (B) A windbreak is a wood with different kinds of trees. (C) A windbreak is a wall of trees to hold soil in place. (D) A windbreak is a wall of wind to fight wind from the opposite way.

Article: A Russian legend has a story about the origins of cats. The cat's coat, it was said, was originally designed for the dog, but the dog became so impatient when coats were being handed out that he was told to wait at the back of the queue. The cat was given the fur instead of the dog. This, according to Russian folk storied, is the origin of why dogs dislike cats. A nameless cat with a taste for travel flew for three weeks between New York and Tel Aviv in 1984. It escaped from its owner's cat-box in the plane's luggage compartment on the first trip and all efforts to get it out with bowls of milk and food failed. After nearly 80,000 miles of flying the airline called in a vet who got it out. The Chinese attitude to the cat was not clear. Cats were welcome for their ability to kill mice and were considered suitable pets for women. On the other hand, they were suspected of bring bad luck into the home. In the days before the invention of the watch, it was said that they used their cats as clocks. The pupils of the cat's eyes were believed to gradually change shape with the position of the sun in the sky. At midday they were a narrow line and they gradually became rounder until sunset. Britain's cleanest cat is undoubtedly Harvey, a five-month-old Persian who climbed into his owner's washing machine. He went through a ten-minute wash cycle before someone noticed him through the glass door, and pressed the "stop" button. Harvey was soon back to his usual self. Cats seem to be able to sense earthquakes. Josie, who lives in California, warned her family of a quake in 1971. She wore her owners. Mr. and Mrs. Miller, at 5:50am by jumping onto the bed and running around. When the Miller followed her out of the house, Josie ran off. The earthquake was only a small one, but the cat raised the alarm every time there was a quake after that.
