Answer:
The passage is from the novel 'To Kill A Mockingbird' by Harper Lee.
Step-by-step explanation:
If the meaning of the passage is being inquired here then in this passage the author has used the words 'solitary mocker' as a reference to the mockingbird throughout the novel who is Boo Radley. The author here means that the 'solitary mocker' or the 'mockingbird' is alone (highlighted by the word solitary) and is defenseless (highlighted by the word blissful unawareness). Also, the author has suggested that in the peaceful environment, the irascible qua-ack of a bluejay is a disruption or a situation of harm as Bob Ewell is reffered to as bluejay in the novel. This passage represents the part where Radley's defenselessness and the disruptive behavior of Ewell is highlighted.
