Which of these lines from the epitaph directly states mrs. purkapile's reason for staying married?
a but a promise is a promise/and marriage is marriage
b i pretended to believe it, though i knew very well/what he was doing
c and out of respect for my own character/i refused to be drawn into a divorce
d by the scheme of a husband who had merely grown tired/of his marital vow and duty.

answer: inference

explanation:

an inference can be understood as a conclusion to which a person is able to get based on reasoning. it is the same as a deduction, a guess, an assumption.   in the sentence presented, the conjunction "but" gives the readers an idea of contrast, and, therefore, allows them to induce that despite the opponent's characteristics, andrea had something different that made her win.
