Anders: The physical structure of the brain plays an important role in
thinking. So researchers developing “thinking machines”—computers that can
make decisions based on both common sense and factual knowledge—should
closely model those machines on the structure of the brain.
Yang: Important does not mean essential. After all, no flying machine closely
modeled on birds has worked; workable aircraft are structurally very different
from birds. So thinking machines closely modeled on the brain are also likely
to fail. In developing a workable thinking machine, researchers would
therefore increase their chances of success if they focus on the brain’s
function and simply ignore its physical structure. In evaluating Yang’s
argument it would be most helpful to know whether
A. studies of the physical structure of birds provided information crucial to the
development of workable aircraft
B. researchers currently working on thinking machines take all thinking to
involve both common sense and factual knowledge
C. as much time has been spent trying to develop a workable thinking machine
as had been spent in developing the first workable aircraft
D. researchers who specialize in the structure of the brain are among those who
are trying to develop thinking machines
E. some flying machines that were not closely modeled on birds failed to work

OA and explanation will folow after discussion.

choose A
Yang claims that structure is important but not essential. therefore, researchers should ignore structure and pay attention to function. He examlifies birds and aircraft.
Hence, if we clarify A, we could safely state whether structure essential or not.

I agree with A.
studies of the physical structure of birds provided information crucial to the
development of workable aircraft
=> Studies of structure of the brain will be crucial to the development of thinking machines.

I also agree with A...we can clearly show that structure is important through this answer

Yang says that while developing thinking machines they should consider only functions and ignore physical structure.

if physical structure of birds is crucial to the development of workable aircraft then his argument becomes invalid

so ans A is essential in evaluating that argument

This is LSAT CR. As per that OA is B.

On another note, how to differentiate between main and sub conclusion?
Is there any particular logic involved?

Thanks

I counter for the idea that answer is (A).

Because the premise of Yang is

(1)."No Flying machine closely modeled on birds has worked."

(2)."Workable aircraft are structurally very different from birds."


When the above two premises have been quoted in the Yang's argument and we also know that in GMAT CR we take premises as true and never doubt them.

Answer choice (A). doubts the above mentioned premises.

GENERAL METHOD:

This is Evaluate The Argument question. If you ask the good question, the argument could be seen as strong or weak. So, the strategy to pick the correct answer is "Variance test". The Variance Test consists of supplying two opposite responses to the question. If different responses produce different effects ==> The answer choice is correct (Power Score CR Bible).

APPLY:

Anders: computers that closely model the structure of the brain will work.
Yang: no flying machine closely modeled on birds has worked; workable aircraft are structurally very different from birds.
Yang's conclusion: researchers would therefore increase their chances of success if they focus on the brain’s function and simply ignore its physical structure.

A. whether studies of the physical structure of birds provided information crucial to the development of workable aircraft?
If YES, Yang's conclusion FAILS because studies of physical structure do help.
If NO, Yang's conclusion is CORRECT because studies of physical structure do not help anything.
==> A is correct choice.


B. Whether researchers currently working on thinking machines take all thinking to involve both common sense and factual knowledge?
"YES" or "NO" does not matter, because B doesn't say anything about physical structure that is the point we want to attack.

C. Whether as much time has been spent trying to develop a workable thinking machine as had been spent in developing the first workable aircraft?
"YES" or "NO" does not matter, because C talks about time ==> out of scope.

D. Whether researchers who specialize in the structure of the brain are among those who are trying to develop thinking machines
"YES" or "NO" does not matter. The point we want to evaluate here is: does physical structure help?. So, D is clearly out.

E. Whether some flying machines that were not closely modeled on birds failed to work
Shell game.
"YES" or "NO" does not matter. Because "some" does not mean "All". So, maybe some flying machines that WERE / WERE NOT modeled on bird MAY work. We can't say Yang's conclusion is right or wrong.

Hope it helps.
