问题 This line of inquiry did not begin until earlier this month--more titan three months after the accident--because there were "too many emotions, too many egos," said retired Adm, Harold Gehman, chairman of the Columbia Accident Investigation Board.
Testifying before the Senate Commerce Committee, Gehman said this part of his inquiry was in its earliest stages, starting just 10 days ago. But Gehman said he already has concluded it is "inconceivable" that NASA would have been unable or unwilling to attempt a rescue for astronauts in orbit if senior shuttle managers and administrators had known there was fatal damage to Columbia’s left wing.
  Gehman told reporters after the hearing that answers to these important questions could have enormous impact, since they could place in a different context NASA’s decisions against more aggressively checking possible wing damage in the days before Columbia’s fatal return.
  Investigators believe breakaway insulating foam damaged part of Columbia’s wing shortly after liftoff, allowing superheated air to penetrate the wing during its fiery reentry on Feb. 1, melt it from inside.
  Among those decisions was the choice by NASA’s senior shuttle managers and administrators to reject offers of satellite images of possible damage to Columbia’s left wing before the accident. The subject dominated the early part of Wednesday’s hearing.
  Gehman complained managers and administrators "missed signals" when they rejected those offers for images, a pointedly harsh assessment of the space agency’s inaction during the 16 day shuttle mission.
  "We will attempt to pin this issue down in our report, but there were a number of bureaucratic and administrative missed signals here," Gehman told senators. "We’re not quite so happy with the process."
  The investigative board already had recommended that NASA push for better coordination between the space agency and military offices in charge of satellites and telescopes. The U.S. National Imagery and Map- ping Agency in March agreed to regularly capture detailed satellite images of space shuffles in orbit.
  Still, Gehman said it was unclear whether even images from America’s most sophisticated spy satellites might have detected on Columbia’s wing any damage, which Gehman said could have been as small as two inches square. The precise capabilities of such satellites proved to be a sensitive topic during the Senate hearing.  [br] According to the writer, what may chiefly be responsible for the Columbia accident?

选项 A、A supposed damage to the left wing of the spacecraft.
B、The deliberate rejection of satellite images offered.
C、A sense of sentiment and arrogance involved.
D、The space agency’s inaction during its mission.

答案 A

解析文中作者明确讲述了导致航天飞机失事可能主要是因为其左翼受到了损坏，因此选项A“飞机左翼可能受到的损坏”为正确选项。而选项B“故意拒绝提供的卫星图像”，选项C“一种感伤而自负的感觉”和选项D“航天机构在执行任务中的行动迟缓”都不是导致事件直接引发的原因。
