PROBLEM: Paragraph- Sent 1: Although Bin Laden, Atef, and KSM initially contemplated using established al Qaeda members to execute the planes operation, the late 1999 arrival in Kandahar of four aspiring jihadists from Germany suddenly presented a more attractive alternative.
Sent 2: The Hamburg group shared the anti-U.S. fervor of the other candidates for the operation, but added the enormous advantages of fluency in English and familiarity with life in the West, based on years that each member of the group had spent living in Germany.
Sent 3: Not surprisingly, Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah would all become key players in the 9/11 conspiracy.
Sent 4: Mohamed Atta was born on September 1, 1968, in Kafr el Sheikh, Egypt, to a middle-class family headed by his father, an attorney.

Sent 11: He appears to have applied himself fairly seriously to his studies (at least in comparison to his jihadist friends) and actually received his degree shortly before traveling to Afghanistan.
Sent 12: In school, Atta came across as very intelligent and reasonably pleasant, with an excellent command of the German language.

Sent 14: This would change, especially as his tendency to assert leadership became increasingly pronounced.
Sent 15: According to Binalshibh, as early as 1995 Atta sought to organize a Muslim student association in Hamburg.
Sent 16: In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians.
Sent 17: Atta proved a poor bridge, however, because of his abrasive and increasingly dogmatic personality.

(A) 1997 (B) 1996, became leader (C) Poor performance as bridge between Muslims and Christians (D) 1995 (E) 1997, became decision maker (F) In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians.
