The distance that animals travel each day and the size of the groups in which they live are highly correlated with their diets. And diet itself depends in large part on the sizes and shapes of animals’ teeth and faces.
The statements above provide the most support for which one of the following?
(A) Animals that eat meat travel in relatively small groups and across relatively small ranges compared to animals that eat plants.
(B) Animals that have varied diets can be expected to be larger and more robust than animals that eat only one or two kinds of food.
(C) When individual herd animals lose their teeth through age or injury, those animals are likely to travel at the rear of their herd.
(D) Information about the size and shape of an animal’s face is all that is needed to identify the species to which that animal belongs.
(E) Information about the size and shape of an extinct animal’s teeth and face can establish whether that animal is likely to have been a herd animal.
Animals teeth and face size and shape >> their diet >> their travel distance and size of their group .
Considering this logical chain, only E suits the structure as no info about animals' veg or non-veg diet, age or health condition are given. E is the OA I think.
