  托福阅读修辞目的题:Tropical Bee Colonies

  【Paragraph 5】Hubbell and Johnson mapped the nests of five of the nine species of stingless bees accurately, and the nests of four these of these species were distributed regularly. All four species with regular nest distributions were highly aggressive to bees from other colonies of their own species. The fifth species was not aggressive, and its nests were randomly distributed over the study area.(Distributions of Tropical Bee Colonies)

  Why does the author indicate that “The fifth species was not aggressive, and its nests were randomly distributed over the study area”?

  ○ To identify research results that contradicted Hubbell and Johnson’s original hypothesis

  ○ To indicate that research results confirmed that nest distribution was related to aggressiveness

  ○ To introduce the hypothesis that, within the same species, not all colonies are aggressive

  ○ To point out that both aggressive and nonaggressive species are equally successful at finding nest sites
