The blue-tipped puffer is a migratory bird that is found along the coast of this state in summer months. The puffers enjoy the seeds of Thomson's Mulberry trees; because these trees are plentiful in the state's Coastal Park, traditionally many blue-tipped puffers would be found in the park during summer months. Ten years ago, the grey fox, a primary predator of the puffer, was re-introduced into the park, and its numbers have been thriving. Over that time, we have seen many fewer puffers in the park during the summer months. Clearly, the puffers are choosing to spend their summers elsewhere.

Which of the following would be the most important to determine in order to evaluate the argument?
  • AWhat other birds and small mammals the grey fox typically hunts besides the blue-tipped puffers. 分析该选项
  • BWhether the grey fox eats the fruit of the Thomson's Mulberry trees. 分析该选项
  • CHow the speed of a blue-tipped puffer during take-off from the ground compares to the speed of a grey fox running 分析该选项
  • DWhether the range of the grey fox within the park extends all the way to the coast. 分析该选项
  • EWhether other coastal areas in the state have seen an increase in the number of blue-tipped puffers over the last decade. 分析该选项
正确答案: E
