"next" is the only one that is used mostly since "the next" sound terrible in a sentence and will automatically make you get an answer wrong if you write it in a sentence
"Then the rebels will overcome the empire's troops and take the city."
This is the answer because it is still hypothetical. The other options imply that it has already happened or is happening, however it is just the fear of the leaders.
(Also, for curiosity's sake- what is the context? It sounds like Star Wars.)
The answer is C) <span>Both Mauryan and Gupta had strong centralized governments.</span>
Answer:
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.
