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".

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
Yes

The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis. <sep>Some of the Sun's energy travels to Earth and becomes energy for what process?<sep>Energy used for photosynthesis
Yes

The judge leaned back in his chair and beckoned to Mr. Andrews. It was finished. Spear was free, and from different parts of the courtroom people were moving toward the door. Their numbers showed that the friends of the young man had been many. Mr. Thorndike felt a certain twinge of disappointment. Even though the result relieved and pleased him, he wished, in bringing it about, he had had some part. He begrudged to Isaacs & Sons the credit of having given Spear his liberty. His morning had been wasted. He had neglected his own interests, and in no way assisted those of Spear. He was moving out of the railed enclosure when Andrews called him by name. "His honor," he said impressively, "wishes to speak to you." The judge leaned over his desk and shook Mr. Thorndike by the hand. Then he made a speech. The speech was about public-spirited citizens who, to the neglect of their own interests, came to assist the ends of justice, and fellow-creatures in misfortune. He purposely spoke in a loud voice, and every one stopped to listen. "The law, Mr. Thorndike, is not vindictive," he said. "It wishes only to be just. Nor can it be swayed by wealth or political or social influences. But when there is good in a man, I, personally, want to know it, and when gentlemen like yourself, of your standing in this city, come here to speak a good word for a man, we would stultify the purpose of justice if we did not listen. I thank you for coming, and I wish more of our citizens were as unselfish and public-spirited." It was all quite absurd and most embarrassing, but inwardly Mr. Thorndike glowed with pleasure. It was a long time since any one had had the audacity to tell him he had done well. <sep>What was the judges result and did it please or displease Mr. Thorndike?<sep>He set Spears free and it pleased  Mr. Thorndike

Yes
