A shift in thought can be indicated by the use of C. an em dash.
An em dash is used to set of an interruption that is closely relevant to the sentence but is not grammatically part of it. These set of interruptions can be found in a list, illustration, restatement, shift in thought or tone, summary, or dramatic point.
Semicolon (;) is used to connect independent clauses.
Ellipses (. . .) are used to indicate that material is missing in the sentence or passage.
For example, indirect characterization describing a protagonist might read, “John snapped at the man without warning,” whereas direct characterization would say simply, “John was short-tempered.”
Some do not pay attention to things like that.
Answer:
I read this story my freshmen year! I love it.
I wrote this last year:
The most important event in "The Dangerous Games," is when Rainsford is getting hunted. At the first part of the story he does not care how animals feel when they get hunted or shot. Now he knows what the animals go through when they are being hunted, because he is the prey. "Don't talk rot, Whitney," said Rainsford. "You're a big-game hunter, not a philosopher. Who cares how a jaguar feels?" So when he says that to his friend Whitney, he does not care about animals or how they feel. "Nerve, nerve, nerve!" he panted, as he dashed along. A blue gap showed between the trees dead ahead. Ever nearer drew the hounds. Rainsford forced himself on toward that gap. He reached it. It was the shore of the sea. Across a cove he could see the gloomy gray stone of the Chateau. Twenty feet below him the sea rumbled and hissed. Rainsford hesitated. He heard the hounds. Then he leaped far out into the sea. . . . " That part of the story he panics, like one of the animals would and does anything to get away from the hunter.
