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

E. infers that watching TV is a consequence of a personality disorder
In the statement above, there is a relation provided between people with certain personality disorders and theta brain waves, a positive correlation. It has also been stated that one's brain waves increases while watching TV. However, notice that these are two independent facts, there is no correlation between people with personality disorders and them watching TV, hence we cannot conclude saying these two statements are dependent.
A. uses the phrase “personality disorders” ambiguously
Not relevant to the paragraph, this has nothing to do with the above conclusions
B. fails to define the phrase “theta brain waves”
Again, this is not relevant to the correlation required between the above conclusions
C. takes a correlation to imply a causal connection
Bang on! This should be the first thing that comes to your mind after reading the above paragraph, the two statements provided above are independent and there is no correlation provided, implying a casual connection
D. draws a conclusion from an unrepresentative sample of data
There is no information provided about where this data is originating from
E. infers that watching TV is a consequence of a personality disorder
Not at all, this is irrelevant, there has been no relation provided between personality disorders and such people watching more/less TV
Answer choice (C)

OFFICIAL EXPLANATION
The correct answer choice is (C).
A correlation involving theta waves, TV watching, and personality disorders is presented in the premises, and then the author concludes that watching too much TV causes a rise in the risk of developing a personality disorder to rise.
Answer choice (A): Although “personality disorders” are left largely undefined (which is acceptable), the term is not used ambiguously.
Answer choice (B): This is not an error because the author is not obligated to define theta brain waves in order to make the argument understandable.
Answer choice (C): This is the correct answer.
Answer choice (D): There is no information to prove that the sample of data used was unrepresentative. Although the researcher says, “my data show...” it is possible the researcher’s data are extensive and representative.
Answer choice (E): This is a Shell Game answer because the researcher infers that the reverse is true.
