GMAT CLUB OLYMPICS: New analyses of the fossil remains of the predator

New analyses of the fossil remains of the predatory theropod dinosaur Spinosaurus aegyptiacus, found in the Bahariya Formation in 1912, suggests that the Spinosaurus aegyptiacus, presumed to be shallow-water species, probably also well-adapted to living on land, as its center of mass was much closer to its hips than previously thought.

Explanation:

Here, the subject of the sentence is "analyses" which is in its plural form. Hence, the verb shall also be in the plural form "suggest".

A. suggests that the Spinosaurus aegyptiacus, presumed to be shallow-water species, probably also well-adapted to living on land, as its center of mass - Incorrect

Verb "suggests" is in the singular form.

B. suggest that the Spinosaurus aegyptiacus, presumed as a species that was living in shallow water, was probably also well-adapted to living on land, so its center of mass - Incorrect

If we correctly understand the meaning of the sentence, the fact that the species' center of mass was closer to the hips is the premise for the conclusion that it could have lived on land. But this option, suggest this fact to be an effect. Hence, this is incorrect.

C. suggests that the Spinosaurus aegyptiacus, presumed as a shallow-water species, was probably also a terrestrial animal, well-adapted to living on land, being that its center of mass - Incorrect

Verb "suggests" is in the singular form.

D. suggest that the Spinosaurus aegyptiacus, presumed to be shallow-water species, probably also well-adapted to living on land, so its center of mass - Incorrect

Here, also, like (B) the cause is presented as the effect. Hence, (D) is also incorect.

E. suggest that the Spinosaurus aegyptiacus, presumed to be a shallow-water species, was probably also well-adapted to living on land, as its center of mass - Correct

This is the correct option as it solves the verb-form error and also correctly presents the cause with the "as" preceding it.

Answer: (E)
