Competition Mode Question



Human beings can see the spatial relations among objects by processing information conveyed by light. Scientists trying to build computers that can detect spatial relations by the same kind of process have so far designed and built stationary machines. However, these scientists will not achieve their goal until they produce such a machine that can move around in its environment.

Which of the following, if true, would best support the prediction above?

(A) Human beings are dependent on visual cues from motion in order to detect spatial relations.
(B) Human beings can often easily detect the spatial relations among objects, even when those objects are in motion.
(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
(D) Although human beings can discern spatial relations through their sense of hearing, vision is usually the most important means of detecting spatial relations.
(E) Information about the spatial relations among objects can be obtained by noticing such things as shadows and the relative sizes of objects

ARGUMENT
[prem] humans can see spatial relations among objects by processing light;
[prem] scientists building computers that can detect these relations have so far designed stationary machines;
[con] they will not achieve their goal unless they produce a machine that can move around its environment;
[asum] we need to link how humans see spatial relations through light + movement.

Ans (A) if humans weren't dependent on cues from motion than the argument would fall.

The answer is option A.

Premise 1: Human beings can see the spatial relations among objects by processing information conveyed by light.
Premise 2: Scientists trying to build computers that can detect spatial relations by the same kind of process have so far designed and built stationary machines.
Conclusion: These scientists will not achieve their goal until they produce such a machine that can move around in its environment.

Necessary Assumption: Only machines capable of moving around can detect spatial relations among objects.

Any answer choice that supports the conclusion that the scientists will not achieve their goal with their current design of machines that are stationary and reinforces the assumption that the detection of spatial relations among objects is only possible for a body capable of motion or for a body in motion will strengthen the argument.

Option A states that Human beings are dependent on visual cues from motion in order to detect spatial relations. This means that the ability of humans to detect spatial relations among bodies hinges on their capability to move, since humans depend on visual cues from motion. This is in line with the argument and the necessary assumption stated above.

The only contender for option A is option B. Option B states that Human beings can often easily detect the spatial relations among objects, even when those objects are in motion. Although option B talks about motion, it rather focuses on the motion of the spatial bodies. But the idea of the argument is not for the spatial bodies themselves to move, but the device or humans who are to detect the spatial relations must rely on their motion. Hence, although B talks about motion, it focuses on the motion of the spatial body themselves without mentioning the need for the detecting body or system to rely on their ability to move in order to detect the spatial relations.

It's clear A.

Premise:
Human beings see the spatial relations among objects by processing information conveyed by light
Stationary machines detect spatial relations by the same kind of process
Conclusion: These stationary machines won't serve the purpose unless they can move around

Clearly there is a gap in the argument. There must be an idea that connects the information processing and the necessity of mobility during the process. (A) is what we're looking for: Human beings are dependent on visual cues from motion in order to detect spatial relations.

(A) Human beings are dependent on visual cues from motion in order to detect spatial relations.
CORRECT ANSWER. This is exactly the logical reason why the scientists will not achieve their goal until they produce such a machine that can move around in its environment.

(B) Human beings can often easily detect the spatial relations among objects, even when those objects are in motion.
If this is true, then the machine doesn't need to be able to move around in its environment

(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
This is a new information that neither supports nor contradicts the prediction.

(D) Although human beings can discern spatial relations through their sense of hearing, vision is usually the most important means of detecting spatial relations.
Detecting spatial relations through hearing neither supports or contradicts the prediction. This information is simply out of scope.

(E) Information about the spatial relations among objects can be obtained by noticing such things as shadows and the relative sizes of objects
There is no logical association between this new information and the prediction. This information is simply out of scope

Final answer is (A)

imo A
we know author says the device should be able to move to be in practical use
so Moving must be important
therefore option A it is as it says moving is important part
