The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.

Question: "What type of nuclear energy process occurs in the sun?"

OPTIONS:
- no
- yes

Answer: "Fusion"

Response: yes

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.

Question: "What are three examples of Mounir er Motassadeq's extremist opinions?"

OPTIONS:
- no
- yes

Answer: "Pressured friend with physical force over religious beliefs"

Response: yes

Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh").

Question: "What other building was on the list of targets besides the U.S. Capitol, the Pentagon, and the World Trade Center?"

ATLANTA, Georgia (CNN) -- On a plot of soil, nestled against the backdrop of skyscrapers in downtown Atlanta, Georgia, a group of residents are turning a lack of access to fresh produce into a revival of old traditions and self-empowerment. Urban farming is a way for African-Americans to connect with the earth, says Cashawn Myers of HABESHA. HABESHA Gardens is one of many urban gardens sprouting up around the country. Fruits and vegetables are thriving in this community garden located in an economically depressed area of the city known as Mechanicsville. But the garden serves an even greater purpose. The harvest helps feed some of the neediest members of the neighborhood. "It's a reawakening going on. It's almost like it's a renaissance," says Cashawn Myers, director of HABESHA Inc. "There's a Ghanaian proverb that says Sankofa. Sankofa means return to your past so you can move forward. Even if you look at coming over here during our enslavement, we were brought here to cultivate the land because that's something we did on the continent. So really, that's what many of the people are doing now," he said. Myers believes urban farming is a way for many African-Americans to reconnect with their past. iReport.com: Show us your urban farm "They are going through a process of Sankofa and going to what they traditionally did, which is connect to the Earth so they can move forward and grow," he says. But HABESHA Gardens isn't unique. Former pro basketball player Will Allen, who is considered to be one of the nation's leading urban farmers and founder of Growing Power Inc., estimates that there are hundreds of thousands of urban gardens in inner cities across America. Urban farms help feed people, sustain neighorhoods " "It's beyond a movement at this point. Its more like a revolution," says Allen.
