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 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. Nonetheless, 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

more rigorous analysis in the form of follow up studies must be conducted the researchers must be more forthcoming in their findings this group displayed a uniform tendency any positive effects will be negated by the effects exhibited by those with sensitivities to caffeine this effectiveness was fleeting, and tended to all but disappear within a week of the study

AB都是针对sensitive people，问题问的是针对insensitive people，也就是调查结果显示对学习有帮助的那群人，的假设

保佑杀鸡上岸

题目问的是who do not display "sensitivities to caffeine,"the author assumes that....注意这里是not，和原文不一样。即不体现出sensitive的一群人会有什么反应。原文说如果是sensitive的人会有各种不适症状，会对学习有不同程度的影响。因此取反来考虑应该就是：没有sensitive的这些人会表现出统一的趋势。
