Difficulty: EasyEliminating Redundancy

When the Voyager 1 spacecraft reached the edge of our solar system, scientists were amazed to detect a low, hum-like vibration in the plasma data; it was audible to the ear, and they heard it.

Which choice best eliminates the redundancy in the underlined portion of the sentence?

  1. A
    it was audible to the ear, and they heard it
  2. it was audibleAnswer
  3. C
    which was audible
  4. D
    it was audible, they heard it

Answer

it was audible
The option 'it was audible' is correct because it removes the repetitive phrases ('to the ear' and 'heard') while maintaining a grammatically complete independent clause after the semicolon.

Step-by-Step Solution

1
Identify the redundant elements in the underlined phrase.
The phrase contains 'audible,' 'to the ear,' and 'heard,' which are repetitive synonyms representing the same concept.
Redundancy must be eliminated to make the sentence concise and clear.
2
Evaluate the grammar of the concise options relative to the semicolon.
The clause following the semicolon must be independent. The option 'it was audible' is an independent clause, whereas 'which was audible' is a dependent clause that creates a fragment.
The correct answer must be grammatically correct as well as concise.
