How does thoreau’s use of rhetorical questions contribute to the persuasiveness and message in “excerpt from ‘civil disobedience? ’”

Here is why Thoreau’s use of rhetorical questions contributes to the persuasiveness and message in “Civil Disobedience”:  A rhetorical question is a question that is asked, but for which an answer is not needed because the answer should be obvious enough to readers/audience members will know what is considered by the author/speaker as the appropriate response.  Rhetorical questions will be used in the place of statements and are used to engage readers and audience members.  When questions are asked, people tend to think a bit deeper into the topic than they would have if just given information in the form of a statement.  Thus, when posed a rhetorical question—a question that has an obvious answer favored by the author—one is more apt to consider and/or accept what is being presented to him or her.  As such, rhetorical questions are persuasive by nature.

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.
