Read the passage.

His only fault indeed seems Modesty. If he were less modest, he would be more agreeable, speak louder & look Impudenter;—and is not it a fine Character, of which Modesty is the only defect?—I have no doubt that he will get more lively & more like yourselves as he is more with you;—he will catch your ways if he belongs to you.
In this passage from “On Making an Agreeable Marriage,” what does Jane Austen say is the problem with Mr. J. P., and what does she advise Fanny to do to change Mr. J. P.?

Mr. J. P. disagrees with people too much; Fanny should tell him he belongs to her.

Mr. J. P. does not talk loud enough in groups; Fanny should tell him to talk more like she does.

Mr. J. P. is shy, so he is not much fun in groups; Fanny should spend more time with him.

Mr. J. P. is too modest to let Fanny look at him; Fanny should try her best to make him feel more comfortable around her.
