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.
"Why do few organisms live on the North and South poles?" is "Sun's magnetic field is strongest"?

Input: Dick was enraged to see how contentedly the men bore the irksome confinement, the meager food, and harsh peremptoriness of the beardless boys set over them as guards. Most of the prisoners passed the time in cards, playing for buttons, trinkets, or what not that formed their scanty possessions. Dick learned that all the commissioned officers of the company with Wesley Boone had been wounded or killed in the charge near the stone bridge. Wesley had been with the prisoners at first. He had been struck on the head, and was in a raging fever when his father and sister came to the prison to take him away. No one could tell where he was now, but Dick knew that he must be in the city, since there were no exchanges, the Confederates allowing no one to leave the lines except women with the dead, or those who came from the North on special permits. Then he visited the provost headquarters, and was shown the complete list of names recorded in the books there; but Barney's was not among them. At the Spottswood Hotel, the day after his coming, he met Elisha Boone, haggard, depressed, almost despairing. Dick had no love for the hard-headed plutocrat, but he couldn't resist making himself known.
"Who visited the provost headquarters?" is "Wesley"?

Input: Joe's parents are farmers and they have a huge farm with cows, chickens, and ducks. Joe loves the farm and all the things he gets to play around and play on. One day, Joe's father told him not to get near a tractor that was sitting in the field. His father was worried that Joe would climb on it and hurt himself. Joe went out to the field and was feeding the horses and cows. When he was done, he saw the tractor his father told him not to get near. He knew that climbing on the tractor wouldn't hurt anything, so he did. He climbed on to the seat and sat there. Then, he pretended he was his father and pretended that he was driving the tractor. Joe's father saw him playing on the tractor and called for him. Joe heard his father calling for him and got off the tractor really fast. When he did that, he fell off and hurt his arm. Joe was in pain and his father came running to check on him and picked him up and sat him on a bench and asked him why he did that. Joe looked at his father and said, "I wanted to be like you." Joe's father gave him a hug and asked him if he wanted to ride with him on the tractor. Joe did and after he got a bandage on his arm, he and his father rode in the field on the tractor.
"What happened to Joe when his father caught him on the tractor?" is "He got off the tractor really fast and fell"?
