Possible Author's tone in GMAT RC

[sexydude05]

Hello friends,
i am a non-native speaker of English. so each and every time i find a qsn based on authors' tone, i find atleast two to three choices for which i have to refer the dictionary. So if possible, can any one of you send me possible exhaustive set of answer choices for author's tone.

Thanks a lot in advance,
Expecting eagerly for your reply.
