plane crash...

Expert replies

Recently, a plane crashed near the outskirts of Berlin within minutes after its takeoff from Berlin airport. Initial analysis confirmed that the crash was caused by either the usage of substandard fuel or a fault in the control board. Since the airport staff tested the control board before the plane took off, analysts hypothesize that the reason behind the plane crash was substandard fuel.


Which of the following options, if true, most strengthens the analysts’ hypothesis?

A. The black box, upon inspection, was found to belong to a generation of models more compatible with fighter planes than with passenger planes.

B. Upon enquiry, the staff at Berlin airport confirmed that they indeed checked the control board before the plane took off.
C. Using a low quality fuel can lead to engine failure and a subsequent plane crash.
D. All the testing conducted by the airport staff is done very extensively to avoid any lapses.
E. The plane belongs to the ZX3V series which contains a fuel combustion engine that is notoriously famous for explosions within minutes after takeoff.
