As an eighth grader, barbara kingsolver reasoned that "everyone with an iota of social position wore polka-dot shirts and miniskirts" in "life without go-go boots." which best describes the way in which this reasoning is flawed?

a it draws a conclusion about a population based on a small sample.
b it reflects the claim of an assumed authority.
c it justifies a wrong with another wrong
d it uses irrelevant evidence to reach a conclusion.

A is the answer you are looking for

A) It draws a conclusion about a population based on a small sample.

Explanation: A flawed reasoning is when we make a conclusion that is wrong because the reasoning that led us to that conclusion, was wrong too. In the given example, the reasoning is flawed because Barbara Kingsolver is drawing a conclusion about a population ("everyone with an iota of social position wore polka-dot shirts and miniskirts") based on a small sample (in this case, probably just a few people she had seen wear polka-dot shirts and miniskirts).
