Sentence Correction: Redundancy - Double Conjunctions or Phrases

Using chest and dental x-rays, anthropological researchers have discovered a new method that can determine the age of a given individual, and although it is still being developed, nevertheless it is already proving to be more effective than current methods.

This answer choice is stylistically flawed. Using both Although and yet, which are both opposition words, creates Redundancy. The use of a Double conjunction is one of the specific redundancies that should always be corrected.

What helps us identify this Redundancy is the following Stop Sign:

Though/Although/Even though/Despite/In spite of... later followed by but/yet/however/still/nevertheless

Incorrect.

Although this answer choice corrects the original Double Conjunction error by removing one of the opposition conjunctions, it creates a Dangling Modifier error. The sentence begins with a modifier: Using chest and dental x-rays. A modifier should be placed right next to the noun it describes. The only noun that this modifier can logically modify is anthropological researchers. The noun anthropological researchers, however, is quite far from the modifier that describes it. Therefore, according to this answer choice, it seems like a given individual's age uses dental and chest x-rays.

What helps us identify this question as a Dangling Modifier question as well as identify the mistake is the following Stop Sign:

A modifier, characterized by all of the following:
1. Verb+ing or Verb in 3rd form
2. Separated from the rest of the sentence by a comma
3. Appears at the very beginning of the sentence

Whenever you see this Stop Sign, focus on the modifier: check whether the noun right after the modifier is indeed the noun that the modifier describes. If it isn't - you've found your mistake.

Incorrect.
