Use the graph and information provided in the paragraph below to answer the following questions.
Flycatcher birds that migrate from Africa to Europe feed their nestlings a diet that is almost exclusively moth caterpillars. The graph below shows the mean dates of arrival, bird hatching, and peak caterpillar season for the years 1980 and 2000.

-If the nestlings of flycatchers are to benefit from the shift in peak caterpillar season from June 3, 1980 to May 15, 2000, in which direction should the May 25, 2000 peak bird hatching date move?

A) to the left so it corresponds to the mean date of arrival in 2000
B) to the left so it corresponds with the new peak caterpillar season in 2000
C) to the right so there is no overlap in the May 15 and May 25 (year 2000) curves
D) no movement is necessary because the caterpillars grow slowly so the nestlings will have enough food to eat
E) no movement is necessary because herbicides can be used to kill the vegetation the caterpillars feed on and therefore the peak hatching time of caterpillars will move to the right from May 15 to May 25, 2000
