Problem: We waited for half an hour, watching the smoke curling over the house, and then, judging that the Indians had made off for fear of being ambushed, we crossed the clearing. It took but a glance to read the story. The women had been washing by the little brook before the cabin, with the children playing about them, when the Indians had come up and with a single volley killed them all except the child we had heard crying. They had swooped down upon their victims, torn the scalps from their heads, looted the house, and set fire to it. We dragged out the body of the woman which had been thrown within, in the hope that a spark of life might yet remain, but she was quite dead. Beneath the warrior Spiltdorph had shot we found the child. It was a boy of some six or seven years, and so covered with blood that it seemed it must be dead. But we stripped it and washed it in the brook, and found no wounds upon it except in the head, where it had been struck with a hatchet before its scalp had been stripped off. The cold water brought it back to life and it began to cry again, whereat Spiltdorph took off his coat and wrapped it tenderly about it.

Question: "Who set fire to and looted the house."

Answer: "Aliens"

Problem: 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.

Question: "What are the two nuclear processes called?"

Answer: "Nuclear energy and nuclear fusion"
Answer: no

Problem: I'm here to tell you the story of a robot named Carl. He came from a far away land known as Factory. Carl was sad because he was missing a part called a tire. He also needed a sun gatherer. But, the tire was more important. Once Carl got all these parts he could travel to his new home in the nation of Lab and the city of Office. It was a tricky thing to get there with missing parts. Just as he had given up hope Carl got a message from Mr. X saying the new parts were ready to be delivered. This made the robot very happy. The parts arrived a few days later and Carl put them in with 2 days of work. After this Carl began to travel the last bit of his goal to get to his new job. After this Carl took 10 days to get to Lab.

Question: "Which parts is Carl the robot missing?"
