Meteorite explosions in the Earth’s atmosphere as large as the one that destroyed forests in Siberia, with approximately the force of a twelve-megaton nuclear blast, occur about once a century. The response of highly automated systems controlled by complex computer programs to unexpected circumstances is unpredictable. 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. B. The system would be destroyed if an explosion of a large meteorite occurred in the Earth’s atmosphere. C. It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon. D. Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast. 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.

IMO E.
It is a Mainpoint question , identify each premises and what conclusion follows it.
A. the system may react in anyway, there is no gurantee that within a centuy it would start a nuclear war.
B. Completely out of scope of the stimulus
C. We never know how the system responds, so we cannot decided it is impossible for the system to distinguish.This conclusion is so specific. moreover note the use of strong word "impossible", in most cases answer choices containing, strong extreme words are not preferred.
D. Out of scope
E. Correct , clearly restates the conclusion in the stimulus. The response of highly automated systems controlled by complex computer programs to unexpected

Clear E Ok, here is the logic System behaves unpredictable , that does not mean that system will start a nuclear war or will get destroyed only option that makes sense is E

I have picked E for this question:
This is a Must Be True question and it is asking you to make a conclusion about the automated system based on the passage.
A. This statement may or may not be true. There is nothing within the passage that leads us to believe that "...the system would react inappropriately..." Therefore, this statement is incorrect.
B. How can we know for sure that an explosion of a large meteorite would destroy the system? It may or may not be destroyed - there is nothing in the passage to back up this statement.
C. Nowhere in the passage does it describe the automated system's ability to distinguish between an explosion from a meteorite and an explosion from a nuclear weapon.
D. How do we know that anything depends on the location of the blast? Again, there is nothing to prove this statement.
E. This is the only reasonable answer choice. This statement is very similar the 2nd paragraph in the passage, so it passes the fact test.
