Question

how does the author use logos to support the argument made in \save the coral reefs\?
by evoking in readers a sense of sympathy for the reefs being destroyed
by helping readers relate to the species that depend on the reefs to survive
by reporting observations of the reefs from percacral scientific research
by providing scientific evidence that humans are destroying coral reefs

Explanation:

Logos is an appeal to logic, often using scientific evidence, facts, or research. Among the options, "by providing scientific evidence that humans are destroying coral reefs" (the last option) fits logos as it uses scientific evidence (a logical appeal) to support the argument. The other options: evoking sympathy is pathos (emotional appeal), relating species is more about connection but not logos, reporting observations from research could be part of logos but the last option specifically mentions scientific evidence of human destruction, which is a clear logical appeal with evidence.

Answer:

by providing scientific evidence that humans are destroying coral reefs
