Keith knew it was his sister's birthday. he didn't want to make a big deal about it. choose the answer in which the syntax best reflects that keith's desire does not conflict with his knowledge. a) because it was his sister's birthday, keith struggled not to make a big deal about it. b) keith knew that it was his sister's birthday, but he didn't want to make a big deal about it. c) keith knew that it was his sister's birthday, and he didn't want to make a big deal about it. d) keith knew that it was his sister's birthday, and he bravely opted not to make a big deal about it.

C is the answer, as the 'and' connecting to two ideas in the sentence doesn't negate or give connotations to his intentions like the other answers did.

c) keith knew that it was his sister's birthday, and he didn't want to make a big deal about it.

Explanation:

We don´t know what does keith do not want to do a big deal about, it could be that it happened something bad to him at school, or that he is down because he broke up with his girlfriend, the sentence that better expresses with no negative or positive connotation, like saying that he didn´t want to make a big deal out of his sister´s birthday, is the third one, "keith knew that it was his sister's birthday, and he didn't want to make a big deal about it"

the answer is: b: however, that doesn’t mean that the current drought isn’t real.
