Question 35

Question

What are the author's TWO main purposes in the text?

A. to explain how humans discovered bioluminescent organisms

B. to describe how scientists have studied bioluminescent organisms

C. to explain how organisms have changed over time to produce light

D. to explain the processes by which some organisms can produce light

E. to describe the various purposes that bioluminescence serves for organisms

F. to describe scientists' persistent questions about the function of bioluminescence

Answer 1

To determine the author's two main purposes in the text, you would need to evaluate the content and focus of the text itself. However, based on the provided options, a reasonable interpretation is as follows:

• If the text focuses on detailing the biological mechanisms and processes that enable organisms to produce light, then the answers would lean towards D (to explain the processes by which some organisms can produce light) and possibly E (to describe the various purposes that bioluminescence serves for organisms).

• If the text includes a historical perspective or a discussion on how scientists have studied these organisms over time, B (to describe how scientists have studied bioluminescent organisms) and F (to describe scientists' persistent questions about the function of bioluminescence) might also be relevant.

Assuming a typical scientific exposition, a likely selection could be D and E. It's best to refer to the specific content of the text to confirm.
