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 ?

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).

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.

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.


Kudos please if you find helpful :)

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.

My pick is C

Meteorite explosions have a force of a twelve-megaton nuclear blast.

Response of highly automated systems controlled by complex computer programs to
unexpected circumstances is unpredictable.

What will a computer do if a twelve-megaton nuclear blast occurs with out a M explosion? It probably would exactly behave as if a M explosion has happened. In essence it won't differentiate between M explosion and Nuclear blast

What is the OA?

Edit: E appears to be a better choice. I should have read it better.



it is written that the response would be unpredictable, whereas the option B says it would be impossible for system, which is extreme.

Though I also selected option E, but I was little confused between C and E. Was option C eliminated due to its comparison with nuclear weapons and which was no where mentioned?

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.

The passage tells us that meteorite explosions can have the same force as a nuclear blast, but that doesn't necessarily imply that it would be IMPOSSIBLE for a highly automated nuclear-missile defense system to tell the difference between a meteorite explosion and a nuclear blast.

Even though the forces are similar, perhaps there are other differences/factors that the computer program could use to distinguish one type from the other. If choice (C) were, "It might be difficult for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon," then (C) would be defensible. However, we do not have enough information to conclude that it would be impossible to tell the difference between these two types of events.

(C) can be eliminated, and (E) is the best answer.

It's a Main Point question.

The frame work to solve these kind of questions should to know what we need to find and what we need to eliminate.

In main point question we cannot let any outside information play with the situation at hand.
We cannot draw any unwanted/unwarranted assumptions about the argument.
What we select should be in-line with the information presented.
The conclusion should also be in scope of the information given in the passage.

With keeping all these things in mind proceed to find the answer choice.

A) Within a century after its construction, the system would react inappropriately and might accidentally start a nuclear war.
NW is not in the scope of the argument.

(B) The system would be destroyed if an explosion of a large meteorite occurred in the Earth’s atmosphere.
What we know is that the response to unexpected circumstances is unpredictable. It's a 180 option and says "the system would be destroyed". It may be the commonsense but necessarily true for this argument.

(C) It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon.
A strongly worded option is not in line with what the passage is saying.

(D) Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast.
The location of the blast is not in the scope of the argument.

(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.
"It is not certain" means system's response is unpredictable and this choice is also in line with what the passage is saying.
