Why is A correct? Why is E incorrect?

@Ryan-Mahabir, Let's look at the structure of the argument. The argument tells us that whether or no one can rightfully call a person's faithfulness a virtue depends in part on the object of that person's faithfulness. The rest of the argument provides specific examples to demonstrate the application fo this principle saying that resentment is a kind of faithfulness but no one considers resentment/ this type of faithfulness virtuous because it is faithfulness to hatred or animosities. Since (E) is one of the examples merely supporting the main conclusion stated in the first sentence (A), we can conclude that it is incorrect. Let me know if you have any further questions.
