Problem: Joey got a German Shepherd for his birthday present. He had never had any pets before, but was always excited to see the other dogs and cats in his neighborhood. Since his birthday was in June, he spent a lot of time playing outside with his new puppy, which he named Max. Max and Joey would often run through fields in a game of chase. They also liked to go through the small forest behind the house, making a game of hide and seek. They never went near the lake because Joey was afraid of water. One day, Max hid a little too well and Joey couldn't find him. Joey spent the afternoon looking for his German Shepherd where they often played, like the field and forest. Joey was a shy boy who often read by himself, and Max was his best friend. After dinner, he went to look for Max one last time before he had to take a bath and go to bed. He heard some barking on the next street, so he ran to see if it was his puppy. Sure enough, he saw Max playing with a poodle. The dogs were having so much fun. Joey brought Max home, happy that he had his puppy back. Max seemed to be happy to have his human by his side as well as a new doggy friend. All summer long, Joey took Max to the poodle's house so they could play without having to worry about losing his present.

Question: "What are two things Joey and Max liked to do together?"

Answer: "Play chess, eat cheese"
Answer: no

Problem: When American 11 struck the World Trade Center at 8:46, no one in the White House or traveling with the President knew that it had been hijacked. While that information circulated within the FAA, we found no evidence that the hijacking was reported to any other agency in Washington before 8:46. Most federal agencies learned about the crash in New York from CNN. Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte Belger, had not been told of a confirmed hijacking before they learned from television that a plane had crashed. Others in the agency were aware of it, as we explained earlier in this chapter. Inside the National Military Command Center, the deputy director of operations and his assistant began notifying senior Pentagon officials of the incident. At about 9:00, the senior NMCC operations officer reached out to the FAA operations center for information. Although the NMCC was advised of the hijacking of American 11, the scrambling of jets was not discussed. In Sarasota, Florida, the presidential motorcade was arriving at the Emma E. Booker Elementary School, where President Bush was to read to a class and talk about education. White House Chief of Staff Andrew Card told us he was standing with the President outside the classroom when Senior Advisor to the President Karl Rove first informed them that a small, twin-engine plane had crashed into the World Trade Center. The President's reaction was that the incident must have been caused by pilot error. At 8:55, before entering the classroom, the President spoke to National Security Advisor Condoleezza Rice, who was at the White House. She recalled first telling the President it was a twin-engine aircraft-and then a commercial aircraft-that had struck the World Trade Center, adding "that's all we know right now, Mr. President." At the White House, Vice President Dick Cheney had just sat down for a meeting when his assistant told him to turn on his television because a plane had struck the NorthTower of the World Trade Center. The Vice President was wondering "How the hell could a plane hit the World Trade Center" when he saw the second aircraft strike the South Tower. Elsewhere in the White House, a series of 9:00 meetings was about to begin. In the absence of information that the crash was anything other than an accident, the White House staff monitored the news as they went ahead with their regular schedules.

Question: "What does NMCC stand for?"

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: "How do nuclear fission and nuclear fusion differ?"

Answer: "Fission causes photosynthesis and fusion doesn't"
Answer:
no
