Which quotes can you found in the book which explain the women who is simply fulfilling their roles as objects of desire, meant to do as men require of them?

Consider Mrs. Bennet sending Jane over the Netherfield on horseback rather than in a carriage, "because it seems likely to rain; and then you must stay all night." (ch 7) She feels that if she dumps her daughter at a rich family's place she will be accepted  more readily than on her own merits. 

I did not understand, will you kindly explain this?
