Input: In chapters 3 and 4 we described how the U.S. government adjusted its existing agencies and capacities to address the emerging threat from Usama Bin Laden and his associates. After the August 1998 bombings of the American embassies in Kenya and Tanzania, President Bill Clinton and his chief aides explored ways of getting Bin Laden expelled from Afghanistan or possibly capturing or even killing him. Although disruption efforts around the world had achieved some successes, the core of Bin Laden's organization remained intact. President Clinton was deeply concerned about Bin Laden. He and his national security advisor, Samuel "Sandy" Berger, ensured they had a special daily pipeline of reports feeding them the latest updates on Bin Laden's reported location. In public, President Clinton spoke repeatedly about the threat of terrorism, referring to terrorist training camps but saying little about Bin Laden and nothing about al Qaeda. He explained to us that this was deliberate-intended to avoid enhancing Bin Laden's stature by giving him unnecessary publicity. His speeches focused especially on the danger of nonstate actors and of chemical and biological weapons. As the millennium approached, the most publicized worries were not about terrorism but about computer breakdowns-the Y2K scare. Some government officials were concerned that terrorists would take advantage of such breakdowns. On November 30, 1999, Jordanian intelligence intercepted a telephone call between Abu Zubaydah, a longtime ally of Bin Laden, and Khadr Abu Hoshar, a Palestinian extremist. Abu Zubaydah said, "The time for training is over." Suspecting that this was a signal for Abu Hoshar to commence a terrorist operation, Jordanian police arrested Abu Hoshar and 15 others and informed Washington. One of the 16, Raed Hijazi, had been born in California to Palestinian parents; after spending his childhood in the Middle East, he had returned to northern California, taken refuge in extremist Islamist beliefs, and then made his way to Abu Zubaydah's Khaldan camp in Afghanistan, where he learned the fundamentals of guerrilla warfare. He and his younger brother had been recruited by Abu Hoshar into a loosely knit plot to attack Jewish and American targets in Jordan. After late 1996, when Abu Hoshar was arrested and jailed, Hijazi moved back to the United States, worked as a cabdriver in Boston, and sent money back to his fellow plotters. After Abu Hoshar's release, Hijazi shuttled between Boston and Jordan gathering money and supplies. With Abu Hoshar, he recruited inTurkey and Syria as well as Jordan; with Abu Zubaydah's assistance, Abu Hoshar sent these recruits to Afghanistan for training.

Does the response "November, 1999" correctly answer the question "On what date did Abu Zubaydah say, "The time for training is over."?"?

- no

General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Noether's theorem allows these quantities to be determined from a Lagrangian with translation invariance, but general covariance makes translation invariance into something of a gauge symmetry. The energy and momentum derived within general relativity by Noether's presecriptions do not make a real tensor for this reason. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of coordinates. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field. This approach has been echoed by Lev Landau and Evgeny Lifshitz, and others, and has become standard. The use of non-covariant objects like pseudotensors was heavily criticized in 1917 by Erwin Schrodinger and others.

Question: "When did the standard approach to energy momentum become criticized?"

OPTIONS:
- no
- yes

Answer: "1907"

Response: no

(CNN) -- Horror-meister, Stephen King calls George Pelecanos "perhaps the greatest living American crime writer." His stories are set in Pelecanos' hometown of Washington, D.C., but this is not the side of the U.S. capitol that you see portrayed on TV with white marble monuments, lawyers and lobbyists. Pelecanos is more interested in working families struggling to get by, the racial tensions in its ethnic neighborhoods and the low-lifes on the edges. His crime-writing peers call Pelecanos the "undisputed poet" of Washington's gritty side. The best-selling and award-winning author is out this week with his 17th and latest novel, "The Cut." It's the first in a new series featuring Iraq war veteran and private investigator Spero Lucas. When he's not working for a Washington defense attorney, Lucas recovers stolen property for a 40% cut. Now, a high-profile crime boss hires Lucas to find out who's been stealing from him, and it could turn out to be Lucas' biggest payday or an untimely end. While Pelecanos made his bones in the noir tradition, there's a definite "Western" feel to "The Cut." The new novel takes place in a morally gray and often violent world. It's peppered with pitch-perfect dialogue and captures the sights, sounds and taste of Washington in rich detail. In short, Pelecanos reads like the real deal. Pelecanos knows a thing or two about capturing the authenticity of urban America with an ethnically and socially diverse cast. In addition to his success as a novelist, Pelecanos is a producer and writer for HBO's New Orleans-set, "Treme." He was previously a producer and Emmy-nominated writer on the hit series "The Wire" and the miniseries "The Pacific." Read an excerpt from "The Cut" CNN recently spoke to Pelecanos about his new novel. The following is an edited transcript. CNN: Tell me more about your new character, Spero Lucas.

Question: "In what type of world does "The Cut" take place?"

Response: "A morally gray and often violent world"

Problem: "What goes up must come down." You have probably heard that statement before. At one time this statement was true, but no longer. Since the 1960s, we have sent many spacecraft into space. Some are still traveling away from Earth. So it is possible to overcome gravity. Do you need a giant rocket to overcome gravity? No, you actually overcome gravity every day. Think about when you climb a set of stairs. When you do, you are overcoming gravity. What if you jump on a trampoline? You are overcoming gravity for a few seconds. Everyone can overcome gravity. You just need to apply a force larger than gravity. Think about that the next time you jump into the air. You are overcoming gravity for a brief second. Enjoy it while it lasts. Eventually, gravity will win the battle.

Question: "What statement is no longer true?"

Answer: "What goes up, must come down"

OPTIONS:
- no
- yes
Answer: yes

Sometimes a full Moon moves through Earths shadow. This is a lunar eclipse . During a total lunar eclipse, the Moon travels completely in Earths umbra. During a partial lunar eclipse, only a portion of the Moon enters Earths umbra. When the Moon passes through Earths penumbra, it is a penumbral eclipse. Since Earths shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse. So unlike a solar eclipse, it doesnt get dark on Earth. Instead it gets dark on the Moon. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse.

Question: "During a lunar eclipse, does the earth or moon get dark?"

Response: "The moon gets dark"
OPTIONS:
- no
- yes

A:
yes
