An inference is a conclusion, that is, to perceive an inference about Mr. Dwerrihouse is to reflect on the facts and statements informed about him in the text and from these facts come to a conclusion about them. These facts can be the characteristics, the behavior of him on something and even the personality that he presents. How should you find these facts in your text and complete a statement about Mr. Dwerrihouse in order to answer your question.
I believe the answer is: B. the shooting of an unarmed rider.
In the speech, there is a dark connotation that made by the speaker when he mentioned the shooting of unarmed riders who are not willing to conform to their orders. Especially to the lower ranks who are bound by the orders from higher officers.
