[Q]: Paragraph- Sent 1: You may wonder if there are other examples of static discharge.
Sent 2: The answer is yes.
Sent 3: Lightning is a form of static discharge.
Sent 4: It is much more dramatic than what happens between you and the door knocker, but it is the same principle.
Sent 5: You can see how it occurs in the following diagram and animation.
Sent 6: You have no doubt seen lightning in a rainstorm.
Sent 7: What does lighting have to do with static electricity?
Sent 8: As it turns out, everything!
Sent 9: During a rainstorm, clouds develop regions of different charges.
Sent 10: This happens due to the movement of air molecules, water drops, and ice particles.
Sent 11: The negative charges are concentrated at the base of the clouds.
Sent 12: The positive charges are concentrated at the top.
Sent 13: The negative charges repel electrons on the ground below.
Sent 14: The ground then becomes positively charged.
Sent 15: Over time the differences increase.
Sent 16: Eventually the electrons are discharged.
Sent 17: This is what we see as lightning.
Sent 18: You can watch an awesome slow-motion lightning strike below. 
Question: How is the top of a cloud different from the base of the cloud during a rainstorm? (A) The positive charges are concentrated at the top (B) Top of cloud is neutral in charge (C) Bottom of cloud has dormant charge (D) He negative charges repel electrons on the ground below (E) Top and bottom clouds have opposite charges (F) Top and bottom clouds are oppositely charged (G) Negative charges are concentrated at the cloud base and positive charges are concentrated at the top.

[Q]: 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: How were liaisons involved in "The Plan" against al Qaeda cells? (A) They provided fund for the plans (B) They offered intelligence and took direct action against al Qaeda (C) Provided intelligence by hired case officers with increased capabilities.
[A]:
B, C.
