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?
A
Located in Brazil, the Amazon Reef is one of the largest known coral reefs in the world.
B
Marine biologist Camille Jazmin Gaynus studies coral reefs, vital underwater ecosystems that provide homes to 25% of all marine species.
C
Providing homes to 25% of all marine species, including up to 8,000 species of fish, coral reefs are vital underwater ecosystems and thus of great interest to marine biologists.
D
As Camille Jazmin Gaynus knows well, coral reefs are vital underwater ecosystems, providing homes to thousands of species of fish.
Explanation
Correct answer: B.
Choice B is the best answer. We’re asked to select the sentence that "introduce[s] the scientist and her field of study." This choice introduces scientist Camille Jazmin Gaynus as a marine biologist and explains what marine life she studies.
Why the other choices are wrong
Choice A
Choice A is incorrect. This choice doesn’t mention Camille Jazmin Gaynus, so it fails to "introduce the scientist."
Choice C
Choice C is incorrect. This choice doesn’t mention Camille Jazmin Gaynus, so it fails to "introduce the scientist."
Choice D
Choice D is incorrect. This choice mentions Camille Jazmin Gaynus, but it doesn’t identify her as a marine biologist. It says she "knows well" about coral reefs, but doesn’t identify her expertise as a "field of study."
