The answer is C. It applies to the most amount of people.
all of the above, because if you volunteered to read the passage to the class, then you would still need to do the work. And if you are listening you have to listen for those main ideas and such, and speaking is pretty much the same as reading.
I would say that the answer is his strength.
During the Trojan War, Achilles was a great warrior known for slaying Hector outside the gates of Troy. His resilience was one of his greatest strengths as he was dipped in the waters of the River Styx in the Underworld as a child, granting him invulnerability all over his body. However, he had one weakness: his heel. His mother held onto his heel while dipping him in the River Styx, and thus, this is the only place on his entire body that could kill him. Achilles got overconfident as a result of his immunity, and he was caught off guard when Paris presumably shot him in the heel with an arrow, killing the great warrior.
