Sent 6: The FAA, the White House, and the Defense Department each initiated a multiagency teleconference before 9:30.
Sent 7: Because none of these teleconferences-at least before 10:00- included the right officials from both the FAA and Defense Department, none succeeded in meaningfully coordinating the military and FAA response to the hijackings.
Sent 8: At about 9:20, security personnel at FAA headquarters set up a hijacking teleconference with several agencies, including the Defense Department.
Sent 9: The NMCC officer who participated told us that the call was monitored only periodically because the information was sporadic, it was of little value, and there were other important tasks.

[EX Q]: Paragraph- Sent 1: Zinni feared that Bin Laden would in the future locate himself in cities, where U.S. missiles could kill thousands of Afghans.
Sent 2: He worried also lest Pakistani authorities not get adequate warning, think the missiles came from India, RESPONSES TO AL QAEDA'S INITIAL ASSAULTS 135 and do something that everyone would later regret.
Sent 3: Discussing potential repercussions in the region of his military responsibility, Zinni said, "It was easy to take the shot from Washington and walk away from it.
Sent 4: We had to live there."Sent 5: Zinni's distinct preference would have been to build up counterterrorism capabilities in neighboring countries such as Uzbekistan.
Sent 6: But he told us that he could not drum up much interest in or money for such a purpose from Washington, partly, he thought, because these countries had dictatorial governments.
Sent 7: After the decision-in which fear of collateral damage was an important factor- not to use cruise missiles against Kandahar in December 1998, Shelton and officers in the Pentagon developed plans for using an AC-130 gunship instead of cruise missile strikes.
Sent 8: Designed specifically for the special forces, the version of the AC-130 known as "Spooky"can fly in fast or from high altitude, undetected by radar; guided to its zone by extraordinarily complex electronics, it is capable of rapidly firing precision-guided 25, 40, and 105 mm projectiles.
Sent 9: Because this system could target more precisely than a salvo of cruise missiles, it had a much lower risk of causing collateral damage.
Sent 10: After giving Clarke a briefing and being encouraged to proceed, Shelton formally directed Zinni and General Peter Schoomaker, who headed the Special Operations Command, to develop plans for an AC-130 mission against Bin Laden's headquarters and infrastructure in Afghanistan.
Sent 11: The Joint Staff prepared a decision paper for deployment of the Special Operations aircraft.
Sent 12: Though Berger and Clarke continued to indicate interest in this option, the AC-130s were never deployed.
Sent 13: Clarke wrote at the time that Zinni opposed their use, and John Maher, the Joint Staff 's deputy director of operations, agreed that this was Zinni's position.
Sent 14: Zinni himself does not recall blocking the option.
Sent 15: He told us that he understood the Special Operations Command had never thought the intelligence good enough to justify actually moving AC-130s into position.
Sent 16: Schoomaker says, on the contrary, that he thought the AC-130 option feasible.
Sent 17: The most likely explanation for the two generals' differing recollections is that both of them thought serious preparation for any such operations would require a long-term redeployment of Special Operations forces to the Middle East or South Asia.
Sent 18: The AC-130s would need bases because the aircraft's unrefueled range was only a little over 2,000 miles.
Question: Who with the help of officers decided to use a plane called "spooky" against Kandahar. (A) Zinni (B) Berger and Clarke (C) The president (D) Shelton in the Pentagon (E) Officers in the Pentagon (F) Schoomaker (G) Al Qaeda (H) Shelton (I) Bin Laden (J) The Halloween monsters.
