The response of highly automated systems controlled by complex computer programs to unexpected

Which of the following conclusions can most properly be drawn, if the statements above are true, about a highly
automated nuclear-missile defense system controlled by a complex computer program?

A. Within a century after its construction, the system would react inappropriately and might accidentally start a
nuclear war.
Incorrect : In a 'Main Point' question, the information in the stimulus is a given - no additional info. can be considered. There is nothing in the stimulus that even remotely implies 'nuclear war'. Hence Eliminated.

B. The system would be destroyed if an explosion of a large meteorite occurred in the Earth's atmosphere.
Incorrect : Such assumption cannot be made. The system could be stored underground for all we know. Eliminated.

C. It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a
nuclear weapon.
Incorrect : This statement is way to extreme and goes to far in stating that it is IMPOSSIBLE for the system to distinguish between the two. UNPREDICTABLE cannot be confused as IMPOSSIBLE. Eliminated.

D. Whether the system would respond inappropriately to the explosion of a large meteorite would depend on
the location of the blast.
Incorrect : Location of the blast is irrelevant to the scope of the stimulus.

E. It is not certain what the system's response to the explosion of a large meteorite would be, if its designers
did not plan for such a contingency.
Correct : This statement reinforces clearly n concisely what is stated in the stimulus above.
