A married couple and their three young adult children , a son and two daughters , live in a large compound with a garden and a swimming pool . A tall fence surrounds the property and the children have never been on the other side of it , for their parents have kept them unaware of the outside world , even of the existence of the telephone . They are taught different meanings for everyday words . For example , they are told that a '' zombie '' is '' a small yellow flower , '' and that '' sea '' is a chair . The parents promise that each child will be ready to venture outside the compound once she or he has lost a dogtooth . Although the children are told they have a brother just on the other side of the barrier , he never appears . The only non-family member to come into the house is Christina , a young woman who works as a security guard at the father's factory . She is driven by the father to the compound traveling both ways blindfolded where she performs sexual favors for the son . Dissatisfied with his preference for intercourse , Christina seeks oral sex from the elder daughter in exchange for a headband. The elder daughter obliges but does not recognize the significance of performing cunnilingus . Later , she gives the headband to her younger sister , in exchange for being licked on the shoulder , Which is marked by an unexplained scar . The parents have tricked the children into believing that overhead planes are merely toys . They allow the children to search for toy planes that they have planted on the grounds , and the child that finds the toy owns it .

Question: "How many people does the headband belong to over the course of the story?"

Answer: "Three"

Response: yes

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: "Who was standing next to the president when his reaction was that the crash of American 11 must be pilot error?"

Answer: "New York"

Response: no

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What are three examples of density given in the article?"

Answer: "Watching a bicycle"

Response: no

Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects.

Question: "What property does the surface of a rubber mat have that prevents us from slipping in wet areas?"

Answer: "Creates friction"

Response:
yes
