   A morally virtuous person is incapable of doing the

   The stimulus says morally virtuous people have repeatedly overcome inclinations to do wrong -- not that they are incapable of doing wrong. Overcoming an inclination means resisting a desire, which is entirely different from being unable to act on it. A person who repeatedly resists the urge to speed is not incapable of speeding. The word "incapable" introduces an absolute that the premises do not support.

   Most people who achieve moral excellence are

   From the premises, we know that moral virtue requires moral excellence. This means all morally virtuous people have achieved moral excellence. We can infer that some people who achieve moral excellence are morally virtuous. But we cannot infer that most people who achieve moral excellence are morally virtuous. There could be many people who achieve moral excellence without becoming morally virtuous -- perhaps moral excellence is necessary but not sufficient on its own. "Most" exceeds what the premises logically guarantee.

   Someone who has no inclination to do anything that is wrong has

   The first premise says moral excellence requires repeatedly overcoming inclinations to do wrong. The contrapositive is: if someone has not repeatedly overcome inclinations to do wrong, they have not achieved moral excellence. This answer says someone with no inclination to do wrong has achieved moral excellence -- which is neither the original conditional nor its contrapositive. Someone with no inclinations to do wrong has no inclinations to overcome, which means they have not met the condition for moral excellence. If anything, this answer contradicts the premises.

   Illegal Negation15% picked this

   Someone who is not morally virtuous is incapable of achieving

   The third premise says moral virtue requires moral excellence (moral virtue leads to moral excellence). The contrapositive is: no moral excellence leads to no moral virtue. This answer negates both sides without reversing: not morally virtuous leads to incapable of moral excellence. That is an illegal negation -- from "virtue requires excellence," we cannot conclude "lack of virtue prevents excellence." Someone who is not yet morally virtuous could still achieve moral excellence; they just have not yet become virtuous through it.

   Every morally virtuous person has been inclined to do something that

   Why this is right

   Chain the premises: moral virtue requires moral excellence, and moral excellence requires repeatedly overcoming inclinations to do wrong. Therefore, every morally virtuous person has repeatedly overcome inclinations to do wrong. To overcome an inclination, one must first have that inclination. Therefore, every morally virtuous person has been inclined to do something wrong. This follows necessarily from the premises -- there is no way to be morally virtuous without having had wrong inclinations to overcome.
