Question:
(CNN) -- The U.S. space shuttle program retired in 2011, leaving American astronauts to hitchhike into orbit. But after three long years, NASA's successor is almost ready to make an entrance. Orion, the agency's newest manned spaceship, is being prepared for its first mission in December. In future missions, it will journey into deep space -- to Mars and beyond -- farther than humans have ever gone before. Orion comes loaded with superlatives. It boasts the largest heat shield ever built and a computer 400 times faster than the ones on the space shuttles. It will be launched into space on the most powerful rocket NASA has ever made. No astronauts will be aboard the December flight, which will test the spacecraft's systems for future manned missions. Final work on the spacecraft is under way at the Kennedy Space Center in Florida. Orion came one step closer to completion this month with the stacking of the crew module atop the service module. "Now that we're getting so close to launch, the spacecraft completion work is visible every day," Orion Program Manager Mark Geyer said in a statement. A 3,600-mile journey When complete, the Orion capsule will resemble a fencing foil, with a tall spire shooting up from a rounded base. At the top will sit a launch abort system, with downward-facing thrusters that would save the crew from a jarring crash in the event of a rocket malfunction. The bottom portion, the service module, will perform various functions such as in-space propulsion and cargo storage. Nestled between the two will be the crew module, capable of supporting human life from launch until recovery. Attached to the service module will be a United Launch Alliance Delta IV Heavy rocket. For the first time since the space shuttle's debut launch in 1981, the crew compartment will ride on the tip of the rocket rather than hanging onto its side, evoking the configuration of the famous Apollo or Gemini missions. After reading the above, is "30 years, from 1981 to 2011" the correct answer to the question "For how many years was the previous space shuttle in use?"?

Answer:
yes

Question:
He repeatedly calls on his followers to embrace martyrdom since "The walls of oppression and humiliation cannot be demolished except in a rain of bullets." For those yearning for a lost sense of order in an older, more tranquil world, he offers his "Caliphate" as an imagined alternative to today's uncertainty. For others, he offers simplistic conspiracies to explain their world. Bin Laden also relies heavily on the Egyptian writer Sayyid Qutb. A member of the Muslim Brotherhood executed in 1966 on charges of attempting to overthrow the government, Qutb mixed Islamic scholarship with a very superficial acquaintance with Western history and thought. Sent by the Egyptian government to study in the United States in the late 1940s, Qutb returned with an enormous loathing of Western society and history. He dismissed Western achievements as entirely material, arguing that Western society possesses "nothing that will satisfy its own conscience and justify its existence." Three basic themes emerge from Qutb's writings. First, he claimed that the world was beset with barbarism, licentiousness, and unbelief (a condition he called jahiliyya, the religious term for the period of ignorance prior to the revelations given to the Prophet Mohammed). Qutb argued that humans can choose only between Islam and jahiliyya. Second, he warned that more people, including Muslims, were attracted to jahiliyya and its material comforts than to his view of Islam; jahiliyya could therefore triumph over Islam. Third, no middle ground exists in what Qutb conceived as a struggle between God and Satan. All Muslims-as he defined them-therefore must take up arms in this fight. Any Muslim who rejects his ideas is just one more nonbeliever worthy of destruction. Bin Laden shares Qutb's stark view, permitting him and his followers to rationalize even unprovoked mass murder as righteous defense of an embattled faith. Many Americans have wondered, "Why do 'they' hate us?" Some also ask, "What can we do to stop these attacks?" Bin Laden and al Qaeda have given answers to both these questions. After reading the above, is "Westerners" the correct answer to the question "Who said all Muslims must take up arms in this fight"?

Answer:
no

Question:
Zakariya Essabar, a Moroccan citizen, moved to Germany in February 1997 and to Hamburg in 1998, where he studied medical technology. Soon after moving to Hamburg, Essabar met Binalshibh and the others through a Turkish mosque. Essabar turned extremist fairly suddenly, probably in 1999, and reportedly pressured one acquaintance with physical force to become more religious, grow a beard, and compel his wife to convert to Islam. Essabar's parents were said to have made repeated but unsuccessful efforts to sway him from this lifestyle. Shortly before the 9/11 attacks, he would travel to Afghanistan to communicate the date for the attacks to the al Qaeda leadership. Mounir el Motassadeq, another Moroccan, came to Germany in 1993, moving to Hamburg two years later to study electrical engineering at theTechnical University. A witness has recalled Motassadeq saying that he would kill his entire family if his religious beliefs demanded it. One of Motassadeq's roommates recalls him referring to Hitler as a "good man" and organizing film sessions that included speeches by Bin Laden. Motassadeq would help conceal the Hamburg group's trip to Afghanistan in late 1999. Abdelghani Mzoudi, also a Moroccan, arrived in Germany in the summer of 1993, after completing university courses in physics and chemistry. Mzoudi studied in Dortmund, Bochum, and Muenster before moving to Hamburg in 1995. Mzoudi described himself as a weak Muslim when he was home in Morocco, but much more devout when he was back in Hamburg. In April 1996, Mzoudi and Motassadeq witnessed the execution of Atta's will. During the course of 1999, Atta and his group became ever more extreme and secretive, speaking only in Arabic to conceal the content of their conversations. 87 When the four core members of the Hamburg cell left Germany to journey to Afghanistan late that year, it seems unlikely that they already knew about the planes operation; no evidence connects them to al Qaeda before that time. Witnesses have attested, however, that their pronouncements reflected ample predisposition toward taking some action against the United States. In short, they fit the bill for Bin Laden, Atef, and KSM. Going to Afghanistan The available evidence indicates that in 1999, Atta, Binalshibh, Shehhi, and Jarrah decided to fight in Chechnya against the Russians. After reading the above, is "Zakariya Essabar and Mounir el Motassadeq" the correct answer to the question "Which cell members were Moroccan?"?

Answer:
yes

Question:
Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects. After reading the above, is "A heavy object presses down with more force. The surfaces are held together more tightly, making the surfaces harder to slide past each other" the correct answer to the question "Why do heavier objects have more friction?"?

Answer:
yes
