文章題目：Distributions of Tropical Bee Colonies
第五題：
Which of the sentences below best expresses the essential information in the
highlighted sentence in the passage? Incorrect choices change the meaning in
important ways or leave out essential information.
highlighted的句子是：
The number of colonies in the study area was not limited by availability of
suitable trees, and a clumped or regular distribution of colonies was not due
to an underlying clumped or regular distribution of potential nest sites.
個人理解：研究地區中蜜蜂群落的數量不局限於仍有多少可做為巢穴的適棲樹種的數量，
且叢聚或規則的群落分佈方式也不是基於具潛力的巢穴是否是叢聚或規則分
佈。
想問的是選項A跟D之間要如何選擇？
A. The limited number of colonies was not due to the distribution or
availability of potential nesting sites.
個人理解：蜜蜂群落的數量限制不是基於潛在巢穴位置的分佈或其可否做為巢穴使用。
D. Neither the number nor the distribution of colonies could be explained by
the availability of suitable nest sites.
個人理解：蜜蜂群落的數量或分佈不能被適合的穴位是否能用來進行解釋。
自己看完覺得兩個答案似乎都能選
真要說的話可能A沒有提到群落的distribution也不是受潛力巢穴的影響
所以選D完整一點
