Choice B is the best answer. In the third paragraph (lines 22-37,"Woman... proudly"), Beecher suggests that women can be "so much respected, esteemed and loved" by those around them that men will accede to their wishes:"then, the fathers, the husbands, and the sons, will find an influence thrown around them, to which they will yield not only willingly but proudly... ." These lines show that Beecher believes women can influence society by influencing the men around them; in other words, women have an indirect influence on public life.
Choices A, C, and D are incorrect because (lines 34-37,"presence... proudly") make it clear that Beecher believes women do have an effect on society, even if it is an indirect effect. Beecher does not indicate that women's effect on public life is ignored because most men are not interested (choice A), unnecessary because men do not need help governing society (choice C), or merely symbolic because women tend to be idealistic (choice D).
