Which of the following statements is an emotional appeal?
d. senator chang has represented our state for the last 12 years.
a. senator chang has experience in dealing with washington.
b. do you really want to take a chance on someone with no experience?
c. he has served on the agriculture committee for the last eight years.

The best answer is B (Do you really want to take a chance on someone with no experience?). This sentence suggests that readers should feel nervous about "taking a chance" on an inexperienced candidate. 

By contrast, A, C, and D are all statements of simple facts that don't really ask readers to feel any particular way at all. Readers might still feel something about those facts, but the statements themselves don't ask readers to feel that way (i.e., the statements don't make an appeal to readers' emotions).
