Propaganda
Explanation:
Hitler used flashy signs and brilliant parades to show what it would be like to be a nazi. This allowed him to become leader of Germany. He then recruited a massive army of nazi soldiers. They were taught to think like hitler (in the sense of racism and world domination) and act upon these desires. This was mainly done theeough Hitler Youth because the younger minds were easier to manipulate. Hitler would also used flouride (which drops IQ for a time when taken in a larger dose than is in toothpaste) to lower soldiers IQ so they would blindly follow him and do everything he said.
Your tone
Let's look at the other choices first. Your credibility is your ability to be believed as trustworthy in regards to the subject. Whether you're talking to a group of teenagers or professional adults, your credibility doesn't change. Your clarity also should not change based on the audience because you want to be clear in your message at all times. Also, your purpose should be the same no matter the audience. The only thing that would change is your tone. The way you approach a crowd of teenagers would vary greatly from the way you'd approach a room of professionals.
Librarian, teacher, doctor, therapist, pretty much all careers require listening and reading skills. You have to be able to listen to people & their questions and a lot of jobs require you to read things, like a lesson plan for a teacher for example. Hope this helps :)
