Which clue best identifies “ocean” as a key term in both passages?

I can’t see the passages but to have “ocean” be a key term I would assume that it is because both of the passages use that word a lot and/or refer to it more than once :)

the correct answer is c. he speculates on what might happen at given points in the future in a world without people. alan h. weisman is an american author, professor, and journalist. authors organize their information with a purpose. they present their ideas in an organized way. this is called text structure. weisman uses text structure so as to improve overall comprehension and to prove his points.

can you take a picture of the passage so i can answer your question
