Question

Consider the following information: - 'P # Q' means 'P is the father of Q'; - 'P + Q' means 'P is the mother of Q'; - 'P - Q' means 'P is the brother of Q'; - 'P * Q' means 'P is the sister of Q'. Which of the following shows that A is the aunt of E?

Accepted Answer

B. Testing option B: $A * B \# C * D - E$ - $A * B \implies A$ is the sister of $B$. - $B \# C \implies B$ is the father of $C$. - $C * D - E \implies C, D, E$ are siblings. Since $A$ is the sister of $B$, and $B$ is the father of $E$, $A$ is the aunt of $E$.
