Final answer:
The question pertains to the use of sound descriptions in literature, emphasizing how different levels of loudness, like whispers and screeches, set the atmosphere and contribute to storytelling in English literature.
Step-by-step explanation:
The student's question is asking about a specific element used in literature to describe the loudness of a sound. The given options can be related to sounds of differing loudness and the context of how they are used.
Based on the information provided, it seems that the question is directed toward understanding the qualities of sound in an English language and literature context.
From the provided passages, one can understand that sounds can range from a low murmur to a loud screech, and these descriptions serve to create a specific atmosphere or to indicate the nature of an event in a narrative.
For example, a whisper might be used in a quiet, tense moment, while a screech might signal alarm or urgency. Both the examples from literature and the science of sound mentioned in the question highlight the importance of sound in communication and storytelling.
In this context, words like rumbling roar, shout, and low and protracted screaming emphasize the intensity and emotional impact of sounds in their respective scenarios. These descriptions are key for readers to imagine the scenes and for characters to convey their feelings and responses to their environment.
