Under which of the following headings is the author most likely to present the problem threatening reefs? BENEATH THE AZURE WATERS LIES A LOST COLONY
UNDERWATER WONDERS
REEFS IN PERIL
THE FUTURE OF THE REEFS

Option C, REEFS IN PERIL

Explanation:

Peril word signifies threat or immediate danger.

Since the reefs are under threat of extinction. The best heading that can justify the endangered reef species is the "option C" i.e Reef in Peril.

However, the other heading like THE FUTURE OF THE REEFS,  BENEATH THE AZURE WATERS LIES A LOST COLONY etc. are also apt but one would not be able to understand that here the author is talking about the reef in danger.

"fire and ice" is one of robert frost's most popular poems. it was published in december 1920 in harper's magazine and in 1923 in his pulitzer prize−winning book new hampshire. it discusses the end of the world, likening the elemental force of fire with the emotion of desire, and ice with hate.

c. the power of desire is greater than the power of hate.
