Neurons in the brain form cohesive decision groups by joining through pathways during any decision making process. The number of neurons that join must be optimal for any decision to be properly made. If more neurons than required join, then the mind may start thinking in tangential direction. If fewer neurons than needed join, then the decision making process may not get done properly.
Which of the following can be drawn on the basis of the information provided in the passage?
A. The optimal number of neurons that an individual needs to make a specific decision can be estimated by monitoring his brain during numerous decision making processes.
B. As the total number of neurons in the brains start to decline after 30 years of age, the decision making capability of an individual also declines.
C. People learn from experience the number of neurons that are optimal for making a particular kind of decision.
D. Its better to have more neurons than to have fewer.
E. Physical proximity defines the neurons that join to form cohesive decision groups during the decision making process.

A) It is stated that an optimal number of neurons must be joined for a proper decision. Furether more the effect of more or less than optimal neurons is also mentioned. Option A says that the optimal number of neurons can be estimated by monitoring the brain. This can be true, can't it? By using scientific techniques we can get the number of neurons. --->CORRECT
B)This is out of scope. Nothing related to neuroons declining asfter 30 years is mentioned.
C)This came close but people can't learn from experience about the optimal number of neurons. This has to be found out scientifically and just not be experience.
D)Not in the scope of the argument. Nothing related to this has been discussed.
E)Neurons join to make decisions. Nothing related to their proximity has been mentioned.

The passage is about humans as a whole and not a single human whoever that may be.

Thus,how can one infer a,bcoz nothing is said about processes mapping anybody individually.

Whereas experience can also mean learning by scientific processes.hence c.


It is kind of taking exceptions into account while speaking about the mass,so a cannot be inferred.
