Certain seed-eating birds are able to crack seeds according to the size of their beaks. Long beaks are able to crack larger seeds, whereas shorter beaks are able to crack smaller seeds. A graph of a bird population with different-sized beaks is shown below. After a several-year drought, smaller seeds became scarce, but drought-resistant trees continued producing larger seeds. What graph would best predict the change in beak length of the bird population?
