TASK DEFINITION: In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".
PROBLEM: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice. <sep>What couldn't the erosion have been caused by?<sep>Wind

SOLUTION: Yes

PROBLEM: Her career started more than 20 years ago in a garage behind a Catholic Worker soup kitchen on skid row in Los Angeles. She lived on a $3-a-week stipend that she spent on pantyhose and bus fare. Her law practice grew to an organization that brought in millions of dollars of damages through its cases against L.A. slumlords, allowing poor families to set up college funds and buy homes. In all those years, she never lost a case. When she stepped down, she had time to notice what was happening to the field of poverty law. "I realized with a shock that the work had really disintegrated and we had lost a whole generation of public-interest lawyers," she said. "It had gone from being an economic sacrifice as it was in my day to an economic impossibility. ... The whole system has essentially collapsed." Mintie also started to ask questions about the medical field. Almost every person who walks into a free medical clinic, she said, faces some legal problem such as an eviction or the loss of Social Security benefits. And many of her clients had medical problems from living in slum housing such as cockroaches lodged in ear canals and rat bite fever, a nonfatal malady that particularly affects children. Mintie noticed that health-care professionals were graduating with staggering debts and also couldn't afford to work with the poor. Her work was noticed by Oprah Winfrey, who invited her on the TV show March 26, 2001. Mintie received a $100,000 "Use Your Life Award" from Oprah's Angel Network, a nonprofit organization that awards money to those who help others. Mintie said that all of the money has gone to her recipients -- none was spent on overhead. She will be out of funds by spring. She is trying to get religious organizations to sponsor recipients. It is a secular organization, but one that grew out of Mintie's religious convictions. <sep>What city did she work in?<sep>Los Feliz

SOLUTION: No

PROBLEM: Albrecht Durer (/'dU@r@r, 'djU@r@r/; German: ['albRect 'dy:Ra]; 21 May 1471 - 6 April 1528) was a painter, printmaker and theorist of the German Renaissance. Born in Nuremberg, Durer established his reputation and influence across Europe when he was still in his twenties, due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by emperor Maximilian I. His vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), retain a more Gothic flavour than the rest of his work. His well-known engravings include the Knight, Death, and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium. Durer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective and ideal proportions. <sep>How old was Durer when he was patronized by emperor Maximilian I?<sep>20
