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.

Hi everyone,

I've a doubt in option E.

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.

though I agree the first part can be deduced from the argument, I'm not satisfied with the 2nd part (in red)

There is no mention of contingency plan in the argument (or any conditional if statement).

IMO - 2nd part doesn't pass the fact test.(must be true answer choices must always pass the fact test).


Regards,
SR

I would reject C only on the basis of the work "impossible"

E- IMO
(1 min 47 sec)
hi,
Am taking around 2 min for this type of questions is there any other way to solve these questions more quickly than it does now. I see people claiming that they could do such problems within 1 min 30 sec or around 1 min.

help appreciated.

I have exactly same doubt which is raised by solitaryreaper

The only thing that is given is that the system's response to unexpected circumstances is unpredictable.

How can the conditional if be inferred ?

Infact the unpredictability of the system is reflected better in the choice C.

But the OA is E, that means I am missing some point.

VeritasPrepKarishma , daagh, egmat , chetan2u - can you please check where am I missing the point ?

Official Guide for GMAT Verbal Review, 2nd Edition

Practice Question
Question No.: 57
Page: 139
Difficulty:


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.


A. Within a century after its construction, the system would react inappropriately and might accidentally start a nuclear war.
System reaction is unpredictable but now where it is given that it will react inappropriately to start a nuclear war.. OUT OF SCOPE.

B. The system would be destroyed if an explosion of a large meteorite occurred in the Earth's atmosphere.
No mention of system getting destroyed in the argument if a large meteorite explodes in 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.
Impossible is too harsh and not apt for the argument given. Argument just says the response of such computer programs is unpredictable.

D. Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast.
Though inappropriate response seems close, argument never said that the unpredictable response will depend on the location of the blast. So, it seems close, lets check next option.

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.
Yes it seems more correct that if the designers did not plan for such a contingency, surely we cannot predict the system's response.

[Reveal] Spoiler:
Answer E

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.
- why is there a timeline? nothing in the passage suggests its only a matter of time. also, nuclear war is a bit extreme.

B. The system would be destroyed if an explosion of a large meteorite occurred in the Earth's atmosphere.
- we don't know how sensitive the system is. what if its indestructible? what if its underground, with tons of barriers between itself and the explosion?

C. It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon.
- extreme language: impossible. also, the passage says the system's RESPONSE is unpredictable, not the DISTINCTION/ABILITY TO DISTINGUISH the explosions.

D. Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast.
- nowhere is it even hinted that location remotely matters.

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 as is

Key here is to IDENTIFY THE CONCLUSION: the response of highly automated systems controlled by complex computer programs to unexpected circumstances is unpredictable
> use POE to elim obviously wrong A/C: A, B & D.

the question stem is about the second sentence, but I think the question stem shows little helpful here.
I remember that Kaplan 800 has the similar question about the warning system for the market of a country.
C is a trap b/c of "impossible".
E sounds like out of scope, but E is correct. The second part of E is the assumption; because of such additional assumption, the pattern in E is rare.
