To protect the colony's brood from extreme heat, honeybees perform a behavior known as fanning. By beating their wings rapidly in a coordinated fashion, they can cool down the temperature of the hive and lower it to a safe level. Which of the following choices best replaces the underlined portion?

  1. A
    they can cool down the temperature of the hive and lower it
  2. they can cool the hiveAnswer
  3. C
    they can cool down the temperature of the hive, this lowers it
  4. D
    which cools the hive

Answer

The correct choice is the option that states 'they can cool the hive' because it removes the redundant repetition of lowering the temperature while keeping the sentence grammatically complete and structurally sound.
The option stating 'they can cool the hive' is correct because it expresses the intended meaning clearly and concisely without repeating synonyms like 'cool down' and 'lower it,' and it maintains proper sentence structure.

Step-by-Step Solution

1
Identify the redundant expressions in the underlined portion of the sentence.
The phrases 'cool down the temperature' and 'lower it' both describe the process of reducing the heat inside the hive, repeating the same concept unnecessarily.
ACT English requires expressing ideas as concisely as possible without repeating synonyms or concepts.
2
Evaluate the grammar of the remaining concise options to ensure they form a complete sentence.
The option stating 'they can cool the hive' forms a proper independent clause that connects logically to the introductory modifying phrase, whereas the other choices introduce either a comma splice or a sentence fragment.
The correct choice must be both concise and grammatically correct.
