Answer:
I'm going to pick the example given in the text of the section lesson. "Jem shuddered. “Like somebody was readin’ my mind. Like somebody could tell what I was gonna do. Can’t anybody tell what I’m gonna do lest they know me, can they, Scout?". The sentences are all shorter, simple sentences. Simple sentences are commonly used to portray somebody young or somebody anxious. In this case, it's both. Jem uses this sentence structure because the rhythm and musicality of the words were different than that throughout the novel. This helps them stand out. The short sentences also point out to the reader that Jem is anxious and is having trouble putting his thoughts together.
 
        
             
        
        
        
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.
