12. If future improvements to computer simulations of automobile crashes enable computers to provide as much reliable information about the effectiveness of automobile safety features as is provided by actual test crashes, then manufacturers will use far fewer actual test crashes. For the costs of designing and running computer simulations are much lower than those of actual test crashes.

Which one of the following, if true, most strongly supports the argument?

(A) Apart from information about safety features, actual test crashes provide very little information of importance to automobile manufacturers.

(B) It is highly likely that within the next 20 years computer simulations of automobile crashes will be able to provide a greater amount of reliable information about the effectiveness of automobile safety features than can be provided by actual test crashes.

(C) If computer simulations will soon be able to provide more information about the effectiveness of automobile safety features, automobile manufacturers will soon be able to produce safer cars.

(D) The cost per automobile of testing and designing safety features is decreasing and will continue to decrease for the foreseeable future.

(E) For years, the aviation industry has been successfully using computer simulations of airplane crashes to test the effectiveness of safety features of airplane designs.

Prethinking : The argument says that if computer simulations provide reliable information about the effectiveness of automobile safety features, then the manufacturers will use far fewer actual test crashes. What if there is some more information other than "effectiveness of automobile safety features" that the manufacturers obtain from actual test crashes ? If that is the case, then the manufacturers cannot completely replace actual test crashes.

Theme : X does something. Y does the same thing, so X can be replaced by Y. Here the unstated assumption is X doesn't do any additional things that Y can't do.

Which one of the following, if true, most strongly supports the argument?

(A) Apart from information about safety features, actual test crashes provide very little information of importance to automobile manufacturers.

This aligns with the prethinking. If the actual tests crash is also used to get information other than "effectiveness of safety features", then the computer simulation cannot replace actual test crash completely and number of actual test crashes will not decrease. So, this option which says there is no other information that manufacturers look in actual test crashes implies that actual test crashes can be replaced with computer simulation and strongly supports the argument.

(B) It is highly likely that within the next 20 years computer simulations of automobile crashes will be able to provide a greater amount of reliable information about the effectiveness of automobile safety features than can be provided by actual test crashes.

Even if computer simulation provides high reliable information about the effectiveness than actual test crashes, the actual test crash will still be used in situations where actual test crash provides more information compared to simulation. Hence this option doesn't strongly support the argument INCORRECT

(C) If computer simulations will soon be able to provide more information about the effectiveness of automobile safety features, automobile manufacturers will soon be able to produce safer cars.

This is related information to the arguments but doesn't strengthen/weaken the argument. INCORRECT

(D) The cost per automobile of testing and designing safety features is decreasing and will continue to decrease for the foreseeable future.

This weakens the argument. If the cost per automobile per test crash is decreasing, then the computer simulation might not replaces actual test crash and hence this option weakens the argument. INCORRECT

(E) For years, the aviation industry has been successfully using computer simulations of airplane crashes to test the effectiveness of safety features of airplane designs.

This is unrelated information. INCORRECT

Hence option A

B

A says that there is some extra important information (very little) that the actual test crashes provide. This supports the actual test crashes and not the computer simulations.
B supports computer simulations by saying that computer simulations might be able to provide more reliable information.
C is out of scope. We are not concerned about the production of safer cars.
D does not support the computer simulations.
E is out of scope.

If future improvements to computer simulations of automobile crashes enable computers to provide as much reliable information about the effectiveness of automobile safety features as is provided by actual test crashes, then manufacturers will use far fewer actual test crashes. For the costs of designing and running computer simulations are much lower than those of actual test crashes.

The Blue part is the conclusion.

Which one of the following, if true, most strongly supports the argument?

(A) Apart from information about safety features, actual test crashes provide very little information of importance to automobile manufacturers.
Contender. Keep it.

(B) It is highly likely that within the next 20 years computer simulations of automobile crashes will be able to provide a greater amount of reliable information about the effectiveness of automobile safety features than can be provided by actual test crashes.
This Could be True. Hence not a Contender.

(C) If computer simulations will soon be able to provide more information about the effectiveness of automobile safety features, automobile manufacturers will soon be able to produce safer cars.
Again Could Be True. Hence not a Contender.

(D) The cost per automobile of testing and designing safety features is decreasing and will continue to decrease for the foreseeable future.
OUt of Scope. Loose it.

(E) For years, the aviation industry has been successfully using computer simulations of airplane crashes to test the effectiveness of safety features of airplane designs.
Totally Out of scope. Loose It.

Hence, We have a clear winner. A

BETWEEN A AND B

(A) Apart from information about safety features, actual test crashes provide very little information of importance to automobile manufacturers.

Doesn't say that simulation does the job better or provides more important info that does actual test. Further, it is nowhere mentioned that actual tests don't provide safety features' information properly.- INCORRECT.

(B) It is highly likely that within the next 20 years computer simulations of automobile crashes will be able to provide a greater amount of reliable information about the effectiveness of automobile safety features than can be provided by actual test crashes.
This clearly gives reason why simulation tests will be used more in future. - CORRECT.

IMO B.

If computer simulations is likely to provide more information about car crashes, then improvements in it will make manufacturers to use fewer actual crash crashes.

The unstated assumption is that actual car crashes do not provide any additional benefit or any useful data because if it does then further improvements in the computer simulation will be useless. Option A is this unstated assumption where it tells us that this is NOT the case.

Key point: There are two ways of strengthening an argument; one by looking for an additional fact; second by looking for an unstated assumption. The latter is a very much common pattern for the official 700 level questions. One must be on the look out for an unstated assumption on these type of questions!

Hope this helps!
