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:

  • Marine biologist Camille Jazmin Gaynus studies coral reefs.
  • Coral reefs are vital underwater ecosystems that provide habitats to 25% of all marine species.
  • Reefs can include up to 8,000 species of fish, such as toadfish, seahorses, and clown triggerfish.
  • The Amazon Reef is a coral reef in Brazil.
  • It is one of the largest known reefs in the world.

The student wants to introduce the scientist and her field of study to a new audience. Which choice most effectively uses relevant information from the notes to accomplish this goal?
