Tortoises that have shells with higher openings can eat taller plants. Others can only reach vegetation
close to the ground. Judging from the differences in
the tortoises’ shells, what kind of vegetation would
you expect to find on the large and small islands?
A. Both islands have a dense ground cover of low-
growing plants.
B. Both islands have similar plants, but vegetation
is more spread out on the large island.
C. On the large island, the land is mostly dry, and
only tall trees grow.
D. The small island is less grassy, and plants grow
with their leaves farther above ground.
