E is fine.

If I see a clause between two commas, i usually delete the clause and then re-read the sentence.
So I read C as,
When they applied a new method for analyzing the chemistry of tooth enamel,....., determining
So they did something,..,determining...(see the difference..?)

I choose E.
The initial phrase "Applying..." is correctly followed by the noun "scientists".

the initial modifier is perfectly fine pointing scientists. and the structure after that is parallel in explaining the idea conveyed: examined and determined

I too fell for C....But rereading the answer choices E seems correct..the two acts of examining and determining seems detached in E whereas determining should follow examining....

and now I read the post is 5 years old :)

Hi all,

The answer here needs to be C. The last part of the sentence uses the word "their" and it needs to definite the prehumans ancestors. In E it defines scientists, and is therefore wrong.

It should be C!

Suggestions?

Let's check between C and E.

The application of a new method for analyzing the chemistry of tooth enamel allows scientists to examine molars of prehuman ancestors and determining that their diets were more varied than had been supposed.

Consider the construction, when they applied a method, they deduced that molars of ...
When you apply a method, you deduce something - the result of an experiment.
Compare the same with option 'C'
(C) When they applied a new method for analyzing the chemistry of tooth enamel, scientists examined molars of prehuman ancestors, determining

'C' is awkward.
By applying a method, they examined molars ... is a better construction.

The next error is with the usage of 'determining' which is acting as noun-ing modifier, modifying (correctly) scientists. No issues with this. But as a consequence, 'that their diets...' also modifies 'scientists' - subject of the preceding clause rather than 'ancestors' - object of the preceding clause.

Note that a pronoun need not always refer to the closest noun. Additionally, 'When they applied ... , scientists... , that their ...' also proves that the pronouns are referring to the same subject - scientists, ambiguously.

All these issues are corrected in 'E'. Underlined the modifiers and subjects for you (always remove the prepositional phrases to see how the subjects and modifiers are used)

(E) Applying a new method for analyzing the chemistry of tooth enamel, scientists have examined molars of prehuman ancestors and determined
