Difficulty: EasyTranslating Literal Statements to Paraphrases

Although the deep ocean is entirely devoid of sunlight, it is far from completely dark. A vast majority of deep-sea organisms generate their own light through a chemical process known as bioluminescence. Unlike the heat-producing light bulbs found in household lamps, bioluminescence is a form of 'cold light,' meaning that less than twenty percent of the reaction's energy is lost as thermal radiation. This efficiency is crucial for survival in the resource-scarce depths, where organisms cannot afford to waste energy. Deep-sea creatures utilize this light for various purposes, including attracting prey, confusing predators, and communicating with potential mates in the vast obscurity of the abyssal zone.

Based on the passage, why is bioluminescence classified as 'cold light'?

  1. Only a small portion of the energy produced during bioluminescence is converted into heat.Answer
  2. B
    Household light bulbs are more efficient at conserving energy than bioluminescent organisms.
  3. C
    More than eighty percent of the energy generated in the reaction is lost as thermal radiation.
  4. D
    Bioluminescent organisms must release heat to survive in the freezing temperatures of the deep ocean.

Answer

Bioluminescence is classified as 'cold light' because only a small portion of the reaction's energy is lost as heat.
The passage explicitly defines 'cold light' as meaning that 'less than twenty percent of the reaction's energy is lost as thermal radiation.' The statement that only a small portion of the energy is converted into heat is a direct and accurate paraphrase of this literal detail.

Step-by-Step Solution

1
Locate the sentence in the passage that explains the term 'cold light'.
The passage states: 'bioluminescence is a form of "cold light," meaning that less than twenty percent of the reaction's energy is lost as thermal radiation.'
This sentence directly defines 'cold light' in the context of bioluminescence.
2
Paraphrase 'less than twenty percent of the reaction's energy is lost as thermal radiation'.
If less than 20% is lost as thermal radiation (heat), then the vast majority of the energy is not turned into heat, meaning only a small portion of the energy becomes heat.
Translating the literal statement to a paraphrase identifies the correct answer choice.
