Consider Lenina's reaction to the Savage Reservation.  Would most others from her society see her as non-conforming, naive, or misanthropic?  Explain.

naive

She clearly isn't non-conforming (rebellious) because she buys into the ideals of cleanliness valued in her society (which are completely absent at the reservation). 

She is also not misanthropic.  She does not despise all humankind... she's just not thrilled with this portion of it.

"Naive" describes her best because she's led such a sheltered life away from this kind of suffering.  Also her reaction is on the immature side.
