Clotilde is giving a speech on why people should adopt a vegetarian lifestyle. In preparation for her speech, she talked to her aunt, who is a vegetarian. Clotilde's aunt told her that meat consumption is the number one cause of cancer in the United States. Clotilde does not verify her aunt's statement but repeats it in her speech.
Which of the following guidelines for ethical speaking did she violate?

A. make sure your goals are ethically sound
B. avoid hate speech
C. raise social awareness
D. be fully prepared for each speech
E. be honest

A. make sure your goals are ethically sound

Explanation:

Clotilde did not verify the information she got from her vegetarian aunt that claimed that meat consumption was the number one cause for cancer in the United States and she went ahead to use such unverified information in a speech.

She violated one guideline for ethical speaking which is that she did not make her speech ethically sound as it contained the opinion of a person but was said in such a way that her listeners would take it as an established fact.

Because of Clotilde's carelessness, she has misinformed sections of the public which goes against the ethic of public speech.
