Ex Input:
Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern. <sep>How do garden warblers use the earth's magnetic field to guide animal migration?<sep>Visual pattern

Ex Output:
No

Ex Input:
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>How long ago was Springfield, Illinois covered by over a mile of ice?<sep>1,200 years ago

No

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>How did Mr. Thorndike feel about the judge making his speech in regards to him?<sep>Glowed with pleasure
