Researchers, investigating the link between daily coffee consumption and learning, claim that subjects who consumed one cup of coffee a day for one week (the equivalent of 50 mg per day) exhibited improvements in declarative memory. Furthermore, the study revealed that such improvements were longer-lasting than those witnessed in a control group served decaffeinated coffee (decaffeinated coffee contains negligible amounts of caffeine). After a week of learning a list of facts, the subjects who consumed one cup of coffee were able to recall these facts with significantly more accuracy.
While daily coffee consumption may aid in the process of forming a greater number of short-term memories and increase the likelihood that these memories will be stored in long-term memory, the study glosses over an important fact. Many exhibit sensitivities to caffeine, including headaches (both migraine and non-migraine), sleeplessness, heightened anxiety, and any number of factors that, when working either alone or in tandem, may actually lead to a decrease in the observed link between caffeine and learning. Nevertheless, despite the fact that the study represents a random sampling— and thus any number of subjects can exhibit any number of reactions to caffeine— if enough subjects continue to display signs of improvements in learning, then this result would not be inconsistent with the study’s findings. Still, until the researchers either release more details of this study, or subsequent studies are conducted, the extent to which those with caffeine sensitivity influenced the observed link between coffee consumption and memory will not be fully known.

Regarding coffee’s effectiveness on memory amongst those who do not display “sensitivities to caffeine,” the author assumes that
A. more rigorous analysis in the form of follow-up studies must be conducted B. the researchers must be more forthcoming in their findings C. this group displayed a uniform tendency D. any positive effects will be negated by the effects exhibited by those with sensitivities to caffeine E. this effectiveness was fleeting and tended to all but disappear within a week of the study

Select the sentence in which the author expresses an opinion toward the results of the study.
While daily coffee consumption may aid in the process of forming a greater number of short-term memories and increase the likelihood that these memories will be stored in long-term memory, the study glosses over an important fact.

Hi Carcass,
For the question 1: In the passage we are told the samplings are not upto the mark and more research needed to be done . Then it should be A, can I know why B is correct.
For question 3: Yes the author mentions that the study glosses over the important fact. But in the last sentence, he clearly mentions that a more in depth research and this is the explanation given for study gloss. Here we need to select the opinion or the reason/explanation for the opinion ? I chose the last sentence, which is wrong

The primary purpose of the passage is to
A. discredit the findings of a study due to flaws in the design of the study
the study is meant to be a demonstration of a finding of which we are not 100% sure. No discredit
B. point out a factor that may modify the extent of certain findings
yes. The study is not conclusive. This is the answer
C. show how results in a finding were unintentionally fabricated
out of scope
D. bolster an argument concerning the interaction of learning and caffeine intake
this is just part of the story not the main idea
E. expand on several oversights of a noteworthy study
out of scope
Regarding coffee’s effectiveness on memory amongst those who do not display “sensitivities to caffeine,” the author assumes that
A. more rigorous analysis in the form of follow-up studies must be conducted this is actually the main idea not the assumption we want to know
B. the researchers must be more forthcoming in their findings nothing about that
C. this group displayed a uniform tendency
the group "sensitive" shows Nevertheless, despite the fact that the study represents a random sampling— and thus any number of subjects can exhibit any number of reactions to caffeine—
This means for the group that is NOT sensitive they have a uniform aspect of the symptoms
D. any positive effects will be negated by the effects exhibited by those with sensitivities to caffeine
too extreme E. this effectiveness was fleeting and tended to all but disappear within a week of the study
not totally true. The effects could be last in the long-term
Select the sentence in which the author expresses an opinion toward the results of the study. In the computer-based test, you’ll click on the sentence in the passage. For this paper-based test, circle the sentence in the passage above.
For this, the question asks for the author opinion NOT for the conclusion which is the last sentence of the passage. Regards

Question 3 really confused me. Doesn't the last sentence point out that the study was inconclusive? Without reading the entire 2nd paragraph , I would still be not clear what the author tries to say. What is the difference between the first and last sentence's roles in the 2nd paragraph?

Question 3 "Still, until the researchers either release more details of this study, or subsequent studies are conducted, the extent to which those with caffeine sensitivity influenced the observed link between coffee consumption and memory will not be fully known."

It is a fact: further researchers are needed to establish the truth or link between blah blah blah

QUESTION #2
(C) is the best answer because the author assumes that those who didn’t display sensitivities to caffeine all had improvements in memory. That is, the passage implies that only those who had adverse reactions to caffeine intake didn’t exhibit the improvements noted in the study. (A) is supported by the passage but doesn’t answer the question. (B) is also supported but doesn’t answer the question. (D) is incorrect because the author implies the opposite: that the positive effects will be more pronounced. (E) isn’t supported by the passage.
