Researcher: People with certain personality disorders have more theta brain waves than those without such disorders. But my data show that the amount of one’s theta brain waves increases while watching TV. So watching too much TV increases one’s risk of developing personality disorders.

A questionable aspect of the reasoning above is that it

(A) uses the phrase "personality disorders" ambiguously
(B) fails to define the phrase "theta brain waves"
(C) takes a correlation to imply a causal connection
(D) draws a conclusion from an unrepresentative sample of data
(E) infers that watching TV is a consequence of a personality disorder

A very simple correlation - causation question.

More personality disorders = More Theta waves.

TV increases Theta Waves. So, author assumed that TV increases personality disorders.

Now, it may happen that either theta waves were causing the disorder or both things occur together rather than one causing another.

(A) uses the phrase "personality disorders" ambiguously --> Irrelevant. He has used it perfectly.
(B) fails to define the phrase "theta brain waves" --> Why do we need the definition? Irrelevant.
(C) takes a correlation to imply a causal connection -->Correct as per our pre thinking.
(D) draws a conclusion from an unrepresentative sample of data --> How do we know it was unrepresentative sample ? May be it was representative sample . Incorrect
(E) infers that watching TV is a consequence of a personality disorder He actually said the other way.



Now it may happen that the relation is

the argument suggests a correlation and causal relationship pattern. In C, "a causal connection" here refers to " People with certain personality disorders" and "theta brain waves", not "watching too much TV " and "the risks"
"unrepresentative sample of data" is why D is wrong.
