[EX Q]: 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.
[EX A]: C

[EX Q]: Article: Rae Armantrout, who has been a poetry professor at the University of California San Diego(UCSD) for two decades, has won the 2010 Pulitzer Prize in the poetry category for her most recent book, "Versed". "I'm delighted and amazed at how much media recognition that the Pulitzer brings, as compared to even the National Book Critics Award, which I was also surprised and delighted to win," said Armantrout. "For a long time, my writing has been just below the media radar, and to have this kind of attention, suddenly, with my 10th book, is really surprising." Armantrout, a native Californian, received her bachelor's degree at UC Berkeley, where she studied with noted poet Denise Levertov, and her master's in creative writing from San Francisco State University. She is a founding member of Language Poets, a group in American poetry that analyzes the way language is used and raises questions to make the reader think. In March, she won the National Book Critics Circle Award for "Versed." "This book has gotten more attention," Armantrout said, "but I don't feel as if it's better." The first half of "Versed" focuses on the dark forces taking hold of the United States as it fought the war against Iraq. The second half looks at the dark forces casting a shadow over her own life after Armantrout was diagnosed with cancer in 2006. Armantrout was shocked to learn she had won the Pulitzer but many of her colleagues were not. "Rae Armantrout is a unique voice in American poetry," said Seth Lerer, head of Arts and Humanities at UCSD. "Versed", published by the Wesleyan University Press, did appear in a larger printing than her earlier works, which is about 2,700 copies. The new edition is scheduled to appear in May.

Options: (A) her 10th book is much better (B) her winning the Pulitzer is unexpected (C) the media is surprised at her works (D) she likes being recognized by her readers
