Paragraph- Sent 1: Conduction is the transfer of thermal energy.
Sent 2: It occurs between objects or substances that are touching.
Sent 3: Thermal conductors are materials that are good conductors of heat.
Sent 4: Thermal insulators are materials that are poor conductors of heat.
Sent 5: Both conductors and insulators have important uses.
Sent 6: Convection is the transfer of thermal energy.
Sent 7: This occurs as particles move within a fluid.
Sent 8: The fluid may be a liquid or a gas.
Sent 9: The particles within the fluid transfer energy by moving from warmer to cooler areas.
Sent 10: They move in loops.
Sent 11: These loops are called convection currents.
Sent 12: Radiation is the transfer of thermal energy by waves.
Sent 13: These waves can travel through empty space.
Sent 14: When the waves reach objects, the heat is transferred to the objects.
Sent 15: Radiation is how the Sun warms the Earths surface.
Question: Waves that transfer thermal energy through empty space are called (A) Convection (B) Conduction (C) Radiation.

Paragraph- Sent 1: The after-action review had treated the CIA as the lead agency for any offensive against al Qaeda, and the principals, at their March 10 meeting, had endorsed strengthening the CIA's capability for that role.
Sent 2: To the CTC, that meant proceeding with "The Plan," which it had put forward half a year earlier-hiring and training more case officers and building up the capabilities of foreign security services that provided intelligence via liaison.
Sent 3: On occasion, as in Jordan in December 1999, these liaison services took direct action against al Qaeda cells.
Sent 4: In the CTC and higher up, the CIA's managers believed that they desperately needed funds just to continue their current counterterrorism effort, for they reckoned that the millennium alert had already used up all of the Center's funds for the current fiscal year; the Bin Laden unit had spent 140 percent of its allocation.
Sent 5: Tenet told us he met with Berger to discuss funding for counterterrorism just two days after the principals' meeting.
Sent 6: While Clarke strongly favored giving the CIA more money for counterterrorism, he differed sharply with the CIA's managers about where it should come from.
Sent 7: They insisted that the CIA had been shortchanged ever since the end of the Cold War.
Sent 8: Their ability to perform any mission, counterterrorism included, they argued, depended on preserving what they had, restoring what they had lost since the beginning of the 1990s, and building from there-with across-the-board recruitment and training of new case officers, and the reopening of closed stations.
Sent 9: To finance the counterterrorism effort, Tenet had gone to congressional leaders after the 1998 embassy bombings and persuaded them to give the CIA a special supplemental appropriation.
Sent 10: Now, in the aftermath of the millennium alert, Tenet wanted a boost in overall funds for the CIA and another supplemental appropriation specifically for counterterrorism.
Sent 11: To Clarke, this seemed evidence that the CIA's leadership did not give sufficient priority to the battle against Bin Laden and al Qaeda.
Sent 12: He told us that James Pavitt, the head of the CIA's Directorate of Operations, "said if there's going to be money spent on going after Bin Laden, it should be given to him.
Sent 13: My view was that he had had a lot of money to do it and a long time to do it, and I didn't want to put more good money after bad."Sent 14: The CIA had a very different attitude: Pavitt told us that while the CIA's Bin Laden unit did"extraordinary and commendable work," his chief of station in London "was just as much part of the al Qaeda struggle as an officer sitting in [the Bin Laden unit]."Sent 15: The dispute had large managerial implications, for Clarke had found Ailies in the Office of Management and Budget (OMB).
Question: Who claimed that James Pavitt said "if there's going to be money spent on going after Bin Laden, it should be given to him." (A) Government (B) Tenet (C) Clarke.
