The three correct examples of logos, which is a rhetorical appeal to logic and reason, are:
C. A candidate for public office runs an ad that plays patriotic music over photos of war veterans. (This appeals to logos by invoking shared values and logic related to patriotism and respect for veterans.)
D. An advertisement for face soap lists the benefits to the skin of each ingredient. (This is a clear logical appeal, providing factual information about the product and its benefits.)
E. A law firm runs an advertisement explaining how the firm can help you win your case. (This relies on logical reasoning to demonstrate the firm's capability and encourage potential clients to choose their services.)
A and B do not primarily appeal to logic; A focuses on emotional appeal, and B appeals to pathos through imagery.
