An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and then select another design that completes that pattern. The results ofthe experiment were surprising. The lowest expenditure of energy in neurons in the brain wasfound in those subjects who performed most successfully in the experiments.

Which of the following hypotheses best accounts for the findings of the experiment?


The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is doing other kinds of reasoning.


Those who performed best in the experiment experiencedmore satisfaction when working with abstract patterns than did those who performed less well.


People who are better at abstract pattern recognition have more energy-efficient neural connections.


The energy expenditure of the subjects' brains increases when a design that completes the initially recognized pattern is determined.


The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest.

 Hide Ans

Option(C) is correct

Option A : The experiment did not compare types of reasoning so this hypothesis does not account for the results.

Option B : No information is provided about subjects' satisfaction, so this hypothesis is not warranted.

Option C : Correct. This statement properly identifies a hypothesis that connects subjects' performance with their energy expenditure and so could account for the experiment's results.

Option D : The most successful subjects would presumably not have completed fewer patterns than average, so the posited increase in energy would likely lead to higher energy expenditures for them, not lower.

Option E : No information is offered on the subjects, so no hypothesis about athletes is warranted.

The correct answer is C.
