In a visual perception experiment, a scientist asked individuals to view a series of patterns displayed on a screen. Each subject was shown seven patterns in quick succession. Subsequently, the scientist showed the same seven patterns in a variety of random orders and in combination with additional patterns. The subject was asked to note each time any of the seven patterns appeared, but the only time that the subject was able to recognize successfully all seven patterns was when they were shown in the exact order as they were shown originally.


If the information in the argument above is true, which one of the following represents the most reasonable inference that can be drawn from the information in the passage?

A. Visual recognition is not correlated to a single occurrence but rather to a connected series.

B. The subjects were unable to identify all seven individual patterns in the original order.

C. The subjects were aware that they were being tested on sequential perception.

D. Each subject could only recognize the original sequence that he had been shown.

E. The subjects were unable to identify any of the original patterns that they had been shown.

Premise 1: In a visual perception experiment, a scientist asked individuals to view a series of patterns displayed on a screen. Each subject was shown seven patterns in quick succession.

Premise 2: Subsequently, the scientist showed the same seven patterns in a variety of random orders and in combination with additional patterns. The subject was asked to note each time any of the seven patterns appeared, but the only time that the subject was able to recognize successfully all seven patterns was when they were shown in the exact order as they were shown originally

Assumption : That all subjects were able to find the patterned series itself and all give the same responses.

Since this being a must be true question, we need to find the fact sets information itself

A) No correlation given in the stimulus
B) Subjects are able to find the series.
C) This information is not given in the stimulus
D) Yes...as per our fact set and assumption
E) They are able to identify..

Option D is the correct answer..

E. The subjects were unable to identify any of the original patterns that they had been shown.


I am struggling to choose between A & D. For me D looks like a conclusion drawn directly from the statement and A looks like correct inference.

Can someone please help me out on this one? Also, if possible, please mention your take on how to differentiate an inference from a conclusion.

Mucho Gracias,

The subject was asked to note each time any of the seven patterns appeared, but the only time that the subject was able to recognize successfully all seven patterns was when they were shown in the exact order as they were shown originally.
it can be inferred from this statement that the individuals were able to recognize some of the patterns from the original seven patterns but not all unless they were shown in the original order. So, "Visual recognition is not correlated to a single occurrence" does not hold.

A. Visual recognition is not correlated to a single occurrence but rather to a connected series.

C. The subjects were aware that they were being tested on sequential perception.

D. Each subject could only recognize the original sequence that he had been shown.

E. The subjects were unable to identify any of the original patterns that they had been shown.


The answer is D

Premise 1:In a visual perception experiment, a scientist asked individuals to view a series of patterns displayed on a screen.
Premise 2: Each subject was shown seven patterns in quick succession
Premise 3: Subsequently, the scientist showed the same seven patterns in a variety of random orders and in combination with additional patterns. The subject was asked to note each time any of the seven patterns appeared


Conclusion: the only time that the subject was able to recognize successfully all seven patterns was when they were shown in the exact order as they were shown originally.



Subjects were able to recognize only the original patterns that they were shown.This means that the original patters were again showed in the same order thus that means the order was also same of the original patterns.

A is a trap as it does not tell us whether the patterns shown were in the same sequence as they were in original.

Also, A speaks about visual recognition. The Argument talks about Visual Perception experiment. I think there is a subtle difference between the two

A. Visual recognition is not correlated to a single occurrence but rather to a connected series.
to Broad of a conclusion.
B. The subjects were unable to identify all seven individual patterns in the original order.
this choice is ok but we have a better answer as this does not talk about the pattern.
C. The subjects were aware that they were being tested on sequential perception.
No such premise provided.
D. Each subject could only recognize the original sequence that he had been shown.
Correct answer as the subject was able to recognize only the original sequence.
E. The subjects were unable to identify any of the original patterns that they had been shown.
the subject was able to recognize.Wrong answer.

If the information in the argument above is true, which one of the following represents the most reasonable inference that can be drawn from the information in the passage?

A. Visual recognition is not correlated to a single occurrence but rather to a connected series. -The passage is about the visual recognition but no such conclusion has been given in the passage.

B. The subjects were unable to identify all seven individual patterns in the original order. -This is opposite of the last line

C. The subjects were aware that they were being tested on sequential perception. -We don't know this information either.

D. Each subject could only recognize the original sequence that he had been shown. -Correct

E. The subjects were unable to identify any of the original patterns that they had been shown. -Can't infer this from the passage

A. Visual recognition is not correlated to a single occurrence but rather to a connected series.

B. The subjects were unable to identify all seven individual patterns in the original order.

E. The subjects were unable to identify any of the original patterns that they had been shown.


The only confusion is between A and B. Always remember that whenever GMAT tests you on inference question, the information is present in the passage or you just need to read between the lines.

It is clearly stated that the only time the subject were able to reckon the data perfectly was during when the same series was run.
