2016安徽皖江联考阅读理解（翻译其中的一段）

问题描述

Researchers acknowledged certain inconclusive variables within their findings. For example, the difference between decaffeinated and regular coffee could not be accurately accounted for, nor could specific recommendations be made for type of tea, though due to its popularity in the Netherlands where the study took place, researchers assumed most tea consumption to be black tea.

请老师翻译一下本段，谢谢！

老师答疑

龙老师：

试译：研究人员承认在他们的发现中有某些不确定的因素。例如，对于去咖啡因的咖啡和普通规咖啡之间的区别无法作出准确的解释，同时，尽管在从事这项研究的荷兰茶是很受欢迎的东西，但也无法针对（该饮用的）茶的类型给出具体的建议，但研究人员假设大多数人喝的茶是红茶。
