Answer

Answer:

A. According to a study of brain activity, the part of the brain that is responsible for planning is thicker in introvert brains. This shows that introverts, who are less impulsive than extroverts, use this part of the brain more.

Brief Explanations:

Evidence A is based on a scientific study of brain activity, which provides objective and empirical support for the claim. It directly links a physical difference in the brain (thicker planning - related part) to a personality trait (introverts being less impulsive). Evidence B, on the other hand, is a subjective opinion of a student. While it supports the claim, it lacks the scientific rigor and objectivity of Evidence A. A single student's belief, even if based on personal observation of friends, is not as strong as a scientific study when it comes to providing evidence for a claim about brain - based personality differences.
