Researcher: People with certain personality disorders have [#permalink]  24 Sep 2012, 00:54
00:00

Difficulty:

25% (low)

Question Stats:

81% (01:59) correct 18% (01:04) wrong based on 54 sessions
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

(D) draws a conclusion from an unrepresentative sample of data not a strong question
(E) infers that watching TV is a consequence of a personality disorder never states that

This is like cause-effect theory. personality disorder=more theta waves;data show that more theta waves while watching TV.
B-cannot be the ans
C- could be
D- Unrepresntative is not correct
E- it has not been inferred as stated here

By the way whats the Official Ans

+1 C

Premise 1 - People with certain personality disorders have more theta brain waves than those without such disorders
Premise 2 - But my data show that the amount of one’s theta brain waves increases while watching TV

Conclusion - So watching too much TV increases one’s risk of developing personality disorders.

Anything which weakens the conclusion is our answer

Option C is our answer as there is a flaw in the reasoning.
