Though Hubbell and Johnson were interested in how bee behavior might affect colony distributions, they recognized that the availability of potential nest sitesfor colonies could also affect distributions.So as one of the first steps in their study, they mapped the distributions of trees suitable for nesting. They found that potential nest trees were distributed randomly through the study area. They also found that the number of potential nest sites was much greater than the number of bee colonies. What did these measurements show the researchers? 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.
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.
A. The limited number of colonies was not due to the distribution or availability of potential nesting sites.
B. There was no lack of suitable trees or potential nesting sites in the study area.
C. The number of nests was directly related to the number or the distribution of suitable trees.
D. Neither the number nor the distribution of colonies could be explained by the availability of suitable nest sites.
distribution of colonies也没有受到clumped 或者 potential nest sites的影响.
A. The limited number of colonies, colonies 没有受到clumped 或者 potential nest sites影响.
B. 这里不缺乏 suitable trees or potential nesting sites
C. nest是和distribution of suitable tree有关系，
由于原文没有提到nest和distribution of suitable tree有直接关系，所以也被排除。
D. colonies的数量不会受到suitable nest sites的影响
