If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Question: "How do clouds develop different regions of charges?"

OPTIONS:
- no
- yes

Answer: "Because of movement of air molecules, water drops, and ice particles"

Response: yes

The Bush administration in its first months faced many problems other than terrorism. They included the collapse of the Middle East peace process and, in April, a crisis over a U.S." spy plane" brought down in Chinese territory. The new administration also focused heavily on Russia, a new nuclear strategy that allowed missile defenses, Europe, Mexico, and the Persian Gulf. In the spring, reporting on terrorism surged dramatically. In chapter 8, we will explore this reporting and the ways agencies responded. These increasingly alarming reports, briefed to the President and top officials, became part of the context in which the new administration weighed its options for policy on al Qaeda. Except for a few reports that the CSG considered and apparently judged to be unreliable, none of these pointed specifically to possible al Qaeda action inside the United States-although the CSG continued to be concerned about the domestic threat. The mosaic of threat intelligence came from the Counterterrorist Center, which collected only abroad. Its reports were not supplemented by reports from the FBI. Clarke had expressed concern about an al Qaeda presence in the United States, and he worried about an attack on the White House by "Hizbollah, Hamas, al Qida and other terrorist organizations." In May, President Bush announced that Vice President Cheney would himself lead an effort looking at preparations for managing a possible attack by weapons of mass destruction and at more general problems of national preparedness. The next few months were mainly spent organizing the effort and bringing an admiral from the Sixth Fleet back to Washington to manage it. The Vice President's task force was just getting under way when the 9/11 attack occurred.

Question: "What types of reporting surged, did the CSG deem all of the reports reliable?"

OPTIONS:
- no
- yes

Answer: "Yes"

Response:
no
