PrepTest 46, Section 3, Question 26
Fossilized teeth of an extinct species of herbivorous great ape have on them phytoliths, which are microscopic petrified remains of plants. Since only phytoliths from certain species of plants are found on the teeth, the apes' diet must have consisted only of those plants.

The argument assumes which one of the following?
None of the plant species that left phytoliths on the apes' teeth has since become extinct.
Plants of every type eaten by the apes left phytoliths on their teeth.
Each of the teeth examined had phytoliths of the same plant species on it as all the other teeth.
Phytoliths have also been found on the fossilized teeth of apes of other extinct species.
Most species of great ape alive today have diets that consist of a fairly narrow range of plants.
