"Pat hung her head without speaking a word" is an example of indirect characterization
Explanation:
Indirect characterization is a strategy that the writer uses to describes characters through their actions, attitude and feellings. In this case, by saying that Pat hung her head without speaking a word, the author is trying to say that Pat could be a reserved person by chosing not to say anything. The writer also suggets that Pat could be depressed.
He stabbed his dad in the leg with scissors, and he was causing trouble at school with some boys. He also killed Bob Ewell when Bob was trying to hurt Scout.
The correct answer is D. A concrete example is one that provides a clear situation in which the abstract idea, in this case the author's argument, is exemplified. This option not only prepares the reader for the example, but also gives specific details about what could be regulated.
