Correct option D

Columnist:
Neuroscientists have found that states of profound creativity are accompanied by an increase of theta brain waves, which occur in many regions of the brain, including the hippocampus.
They also found that listening to music increases theta waves dramatically.
Thus, one can attain a state of profound creativity merely by listening to a tape of recorded music

The columnist’s reasoning is most vulnerable to criticism on the grounds that it
(A) takes for granted that there is a causal connection between the hippocampus and being in a state of profound creativity - Wrong - Irrelevant

(B) fails to consider that music is not necessary for one to be in a state of profound creativity
Wrong : - exact opposite of passage conclusion

(C) does not rule out the possibility that listening to music by means other than a tape recording also increases theta waves
- Wrong: Rule??

(D) ignores the possibility that an increase in theta waves may not always be accompanied by a state of profound creativity
Correct : if their is any other way, which author is not considered, then all the argument purpose is demean.

(E) provides insufficient reasons to believe that people who are not in states of profound creativity have low levels of theta brain waves
Wrong: - irrelevant, as topic does not discuss about low or high level of theta brain and in state or out state.

Columnist-->Neuroscientists-->
Theta waves increase(accompanying not causing) ---> creativity increases to profound level
Music increases --> theta waves increase
=> Music increases(cause) --> creativity increases to profound level

Two events when co-exist does not mean one is the cause for the other. This is the weakness that we need to match with the answer choice.


(A) takes for granted that there is a causal connection between the hippocampus and being in a state of profound creativity
Connection between hippocampus with creativity is irrelevant to the argument. Eliminate.

(B) fails to consider that music is not necessary for one to be in a state of profound creativity
This is an extreme case, and there may be few cases where music may be necessary for creativity and hence this may not be completely true. Hence, it cannot be used as a criticism. Eliminate.

(C) does not rule out the possibility that listening to music by means other than a tape recording also increases theta waves
Means of music is irrelevant to the argument. Eliminate.

(D) ignores the possibility that an increase in theta waves may not always be accompanied by a state of profound creativity
This is correct as per the analysis. So, the correct choice is D.

(E) provides insufficient reasons to believe that people who are not in states of profound creativity have low levels of theta brain waves
People without profound creativity is irrelevant to the argument. Eliminate
