Answer:
c. has little regard for her sister's well-being
Explanation:
Read the excerpt from "Why the Sun Is Brighter Than the Moon.”
When they were very young, Buwan pushed Araw into a fast-flowing stream.
"Sister, my sister, I’m losing my grip! Grab my hand!” cried Araw, her small hands clinging onto the slippery banks.
"No, sister, I won’t,” replied Buwan, "for you will pull me in too!”
Another time, Araw caught a cicada and put it in a cage she’d made out of bark. Buwan grabbed the cage and shook it.
"Sister, my sister,” cried Araw, "please be careful, because that is a present for our father.”
Buwan refused to help Araw when she fell into the river, which shows that she doesn't really care about what happens to her. Araw is not treacherous, which is why d is out. Buwan never cared about Araw's intelligence, you can't lose something you never had, and it doesn't really talk about intelligence, so b is out. And a is obviously not an option because Buwan is bitter and doesn't appreciate Araw. :) Hope this helps
