I chose answer choice 'A' and I'm having a hard time understanding why 'B' is the correct answer.

From my understanding, the relationship between cognitive interview and instructed eye-closure techniques is as follows:
Eye-closure techniques can have just as good of witness recall as cognitive. However, eye-closure techniques are not as complex and it has greater benefits.

With answer choice 'B', I'm seeing that a reduced consumption of saturated fat is COMBINED. I don't see how that relationship is analogous to that of cognitive and eye-closure techniques which seem to work independently from each other.

Hi Fersian!

Parallel questions within RC can often be major league pains in the butt, so I want to help get to the bottom (no pun intended) of this particular question.

The passage mentions two different methods for increasing the amount of data reported in witness interviews, but both cognitive interviews and hypnosis had their shortcomings. The issues with cognitive interviews didn't stem from the process being ineffective, rather that it demanded a high level of training and large amount of time spent to be used properly, and that combination was not always possible. Hypnosis had in my opinion larger issues, and even though it was less complex than cognitive interviews, those issues rendered the method significantly far from ideal.

The passage suggested that a core element to both methods, the instructed eye-closure, may be the best method yet to overcome the inherent issues with both cognitive interviews and hypnosis.

The relationship between cognitive interviews and eye-closure is that eye-closure involves just a part of the cognitive interview process. Eye-closure seems to have just as many positive effects as the cognitive interviews but is free from the burdens associated with the interviews, so it became the author's recommended method.

Now let's break down why B works so well here. Here are the parallel connections between the passage and the subject matter in the answer:

Health benefits = witness recall ability

Increased consumption of fiber alone= instructed eye-closure

Reduced consumption of saturated fat and increased consumption of fiber = cognitive interviews

Much like in the passage, the less complex (or partial/light) method has as many positive benefits as the more complex process.

To respond directly to your issue, it's not that eye-closure and cognitive interviews are "independent" of each other, it's more appropriate to see eye-closure being just one component to the more complex process of the interviews.

A falls short of being correct when it implies that individuals see as much benefit from engaging "in more strenuous exercise on a less frequent basis." That falls short of the whole/part relationship we wanted in regards to how the cognitive interview relates to the instructed eye-closure.

I hope that helps!

Hi, could someone explain why E is wrong? I've read the explanations above and think I am confusing the parallel connection. For E, I was thinking the "diet and exercise" are the cognitive and closing-eyes combination and that the statement "less significant benefits can be achieved through exercise alone" was paralleling the idea that cognitive or eyes-closed would not be as helpful separately as they are together. Thanks!

Hi Abby!

It sounds like you've drawn correct parallels between answer choice (E) and the passage. The issue with answer choice (E) is that we want to say that eye-closing alone is just as effective as cognitive interviews + eye-closing. This is strongly suggested in line 57 of the passage: "More significantly, instructed eye-closure by itself appears to improve witness recall to a degree equivalent to that demonstrated by the cognitive interview."

Thus, answer choice (E) is incorrect because it is not consistent with the idea prevalent in the passage - simpler methods can be just as effective as their more complex counterparts. For answer choice (E) to be correct, it would have had to say that the same benefits can be achieved through exercise alone. Hope this helps!
