A population of fruit flies on an island lay their eggs in some rotting fruit. Some of the fruit is blown into the ocean by a storm and washes up on another island that is too far apart for the flies to fly back to their original island. Over time the two populations change so much that they are different species. What must be true of the two populations of flies at this point?

They no probably no longer eat the same things, or one of the populations has adapted to its environment and the other flies continue to be normal. 

Answer:

The correct answer would be "the two population must not able to interbreed".

Species is defined as the group of organisms in which male and female organisms are able to breed successfully that is, they are able to produce a viable offspring.

Members of two species are not able to interbreed successfully naturally.

As it is provided that the two populations have evolved (geographical isolation) into two different species then, they must not be able to interbreed successfully.
