Emotional and logical appeals work together by ________.

A) allowing the audience to choose the appeal that will be most effective
B) providing rational support for an idea that an audience has already emotionally accepted
C) manipulating the audience into focusing on the emotional issues while ignoring the logical elements
D) doing all of the above

Emotional appeals can capture the audience's attention and persuade them to consider a topic. Logical appeals then provide rational support for the idea that the audience has already emotionally accepted, making the argument more compelling and convincing. This combination can be particularly effective in changing attitudes or behaviors. Option A is not accurate as emotional and logical appeals are usually used together and not selectively. Option C is incorrect, as manipulating an audience in this way would be unethical and counterproductive. Option D includes Option C which is incorrect, thus the best choice would be B.
