Difficulty: Very hardEliminating Redundancy

Biologists studying deep-sea hydrothermal vents discovered a species of extremophile shrimp that thrives in superheated water. Although these organisms are currently existing today in environments that would kill most marine species, they have developed unique proteins to stabilize their cellular structure.

Which of the following choices, if substituted for the underlined portion, best eliminates the redundancy in the sentence?

  1. A
    NO CHANGE
  2. Although these organisms exist in environmentsAnswer
  3. C
    These organisms exist in environments
  4. D
    Because, although these organisms exist in environments

Answer

The correct choice is the option that states 'Although these organisms exist in environments' because it eliminates the redundant time indicators and maintains proper sentence structure.
The correct choice, which begins with 'Although these organisms exist in environments', successfully removes the redundant words 'currently' and 'today' while maintaining the subordinating conjunction 'Although' to properly link the dependent clause with the independent clause.

Step-by-Step Solution

1
Identify the redundant words in the underlined portion.
The words 'currently', 'existing', and 'today' all convey the exact same meaning of present existence.
To recognize which elements are unnecessary and should be removed to make the sentence concise.
2
Test the remaining choices in the context of the full sentence to evaluate grammatical correctness.
Removing the subordinating conjunction 'Although' creates a comma splice, while adding 'Because' turns the entire sentence into a fragment. Only the correct option maintains the appropriate subordinating structure.
To ensure that eliminating redundancy does not introduce a new grammatical error.
