Because fables have been around since before we had any type of documentation. Throughout the years they get passed down vocally.
Answer:
........What is this for?
Answer: B. By giving a specific example of a tragedy caused by indifference
Explanation:
Logos is referred to as an appeal to logic and a way by which the audience can be persuaded with reason, through the use of facts and figures when crafting a persuasive writing.
Wiesel is establishing logos in this passage by giving a specific example of a tragedy caused by indifference. In this case, by giving a example of indifference, Wiesel is giving further information to persuade the audience.
So here's my "translation" of each of the passages:
A. I'm really in love you, Romeo, and I really am telling the truth!
B. I'm so in love with you I forgot how to count, and I think three is four. Regardless, if you really do love me, tell me tomorrow and we can get married then.
C. Unless you're about to change your mind about loving me, don't say that you love me like something that changes, because that means that your love for me will change.
D. Darn, I really love you, so much that I'm murderous towards you, and I can barely handle being away from you.
Okay, those were more for comic relief, but they were very, very loose translations of those snippets of texts. So, with them, we can clearly see that C is the right answer.
