Practice one SAT question at a time

Questions come from the Bluebook question bank.

While researching a topic, a student has taken the following notes:

  • Bioluminescence is the emission of light by living organisms.
  • This light is produced by chemical reactions in organisms’ cells.
  • Jellyfish emit flashes of blue light.
  • This behavior serves to startle predators.
  • Black dragonfish emit a steady red light.
  • This behavior helps them locate prey in deep waters.

The student wants to emphasize a difference between the behavior of jellyfish and that of black dragonfish. Which choice most effectively uses relevant information from the notes to accomplish this goal?
