Ms$.$ Hampton left high school before graduation to take a job as a clerk in a store. Although still a clerk, she has always had steady work and an income sufficient to enable her to marry, buy a home, equip and maintain it in a very comfortable manner, although this has required her to do without many other things $($e$.$g$.,$ children, social$-$recreational activities, etc.$).$ When Ms$.$ Hampton is with other people in an informal group, her chief topic of conversation is the quality and cost of the various articles she has purchased for her home. The reason for Ms$.$ Hampton's chief topic of conversation is:

a$.$ She has ideals of quality and believes "production should be for use rather than for profit."

b$.$ She wishes to keep conversation limited to subjects on which she is informed.

c$.$ By talking about subjects on which she is informed, she diverts conversation from subjects she is ignorant of$,$ but which most people are informed about and interested in$.$

d$.$ She wishes to appear pleasant, to make conversation, and to avoid giving offense.
