Step 1
Step 2
B. no long-beaked bugs existed prior to the introduction of the golden rain tree.
Answer
This statement cannot be definitively concluded based on the available information, as it only addresses the effects of the golden rain tree and does not provide details on the existence of long-beaked bugs before its introduction.
Step 3
C. the diameter of the golden rain tree fruit acted as a selection pressure on beak length.
Answer
This conclusion is reasonable, as the change in fruit diameter likely influenced the feeding behavior of the bugs, thereby affecting the beak length of those that consumed it. This illustrates a clear example of natural selection.
Step 4
D. the response of an individual golden rain tree to predation by soapberry bugs would be to grow larger fruit.
Answer
This statement implies a direct adaptive response from the tree, which does not accurately represent ecological interactions. Individual trees cannot consciously respond to predation by altering their fruit size.
