Q: Oh no! Your younger sister just mixed up all of your LEGO parts. Now you have to put them all back into the original categories. How will you do this? You sort them by size and shape until they are each back into their specific place in the tray. What do you think you could have called the mess your younger sister created? Thats right, it is a mixture. Fortunately, it was a physical change and she just made a simple mixture. You are able to separate them back into order. Its a good thing she did not toss them into the fireplace. That would have caused a chemical change as they all melted together. If your LEGOs were melted, you would be out of luck for building that next big project. <sep>Why do you have to sort your LEGOs and put them in the tray?<sep>Your sister mixed them together

A: Yes

Q: IBM opened a sprawling and sophisticated semiconductor factory here on Wednesday that cost more than $2.5 billion to build and equip, the largest single capital investment the company has ever made. The factory, which opens as the computer chip business is in a slump, is a costly and risky move for IBM. But it is also an expression of confidence by the company that it can remain a technology leader in the highly competitive global semiconductor industry, and a commitment that the best place to execute that strategy is in upstate New York. IBM is an exception among computer makers in that it still invests heavily in research to advance the design, manufacture and materials used in semiconductor chips. It is spending more than $500 million a year on semiconductor research and development. The factory will produce a wide range of specialized semiconductors used in everything from the largest mainframe computers to cell phones and video-game consoles. The new plant is part of IBM's push to gain a strong lead in chip-making beyond the personal computer business, where Intel and East Asian chip producers hold the advantage. "The core of our strategy is to lead in technology and attack the high-performance segments of the market," said John Kelly, senior vice president in charge of IBM's technology group. An advantage to having the semiconductor fabricating factory here, Kelly explained, was that it was very close to its research laboratories in nearby Westchester County, N.Y. To stay ahead in advanced chip technology, he said, moving innovations out of the labs and into the factory as fast as possible is crucial. "What we call the lab-to-fab time should be as close to zero as possible," Kelly said. "If our strategy were anything but to be on the leading edge, we'd have put the plant in Asia." The new factory, which will begin normal production early next year, will employ about 1,000 people. <sep>What does IBM's senior vice president in charge of their technology group, John Kelly, feel that the location of the new plant is so important?<sep>To increase the lab-to-fab time

Q: In March 2001, Rice asked the CIA to prepare a new series of authorities for covert action in Afghanistan. Rice's recollection was that the idea had come from Clarke and the NSC senior director for intelligence, Mary McCarthy, and had been linked to the proposal for aid to the Northern Alliance and the Uzbeks. Rice described the draft document as providing for "consolidation plus," superseding the various Clinton administration documents. In fact, the CIA drafted two documents. One was a finding that did concern aid to opponents of the Taliban regime; the other was a draft Memorandum of Notification, which included more open-ended language authorizing possible lethal action in a variety of situations. Tenet delivered both to Hadley on March 28. The CIA's notes for Tenet advised him that "in response to the NSC request for drafts that will help the policymakers review their options, each of the documents has been crafted to provide the Agency with the broadest possible discretion permissible under the law." At the meeting, Tenet argued for deciding on a policy before deciding on the legal authorities to implement it. Hadley accepted this argument, and the draft MON was put on hold. As the policy review moved forward, the planned covert action program for Afghanistan was included in the draft presidential directive, as part of an "Annex A" on intelligence activities to "eliminate the al Qaeda threat." The main debate during the summer of 2001 concentrated on the one new mechanism for a lethal attack on  Bin Laden-an armed version of the Predator drone. In the first months of the new administration, questions concerning the Predator became more and more a central focus of dispute. Clarke favored resuming Predator flights over Afghanistan as soon as weather permitted, hoping that they still might provide the elusive "actionable intelligence" to target  Bin Laden with cruise missiles. Learning that the Air Force was thinking of equipping Predators with warheads, Clarke became even more enthusiastic about redeployment. The CTC chief, Cofer Black, argued against deploying the Predator for reconnaissance purposes. He recalled that theTaliban had spotted a Predator in the fall of 2000 and scrambled their MiG fighters. Black wanted to wait until the armed version was ready. "I do not believe the possible recon value outweighs the risk of possible program termination when the stakes are raised by the Taliban parading a charred Predator in front of CNN," he wrote. <sep>In the debate over the use of armed Predator drones what position did Clarke favor?<sep>He wanted to end all use of Predator drones

No
