In a family of six members, $A,B,C,D,E$ and $F$, there are two married couples. $D$ is a teacher and the father of $E$. $F$ is the grandmother of $E$ and a housewife. $C$ is a lawyer and married to $A$. $B$ is not a male. How is $B$ related to $E$?

Let's reconstruct the family tree step-by-step from the given statements:
1. $D$ is male (father of $E$) and a teacher.
2. $F$ is female (grandmother of $E$) and a housewife. Since $F$ is a grandmother, she belongs to the first generation.
3. There are two married couples. $C$ (lawyer) is married to $A$.
4. Since $D$ is a father, he must be married. $F$ is a grandmother, meaning she was married (her spouse is either deceased or not part of the 6 members, or one of the couples belongs to generation 1 and one to generation 2).
5. Let's look at generations:
* Gen 1: Grandmother $F$.
* Gen 2: Father $D$.
* Gen 3: $E$.

6. The couples must be distributed. $C$ and $A$ are married. $D$ must have a wife. Since $B$ is not male, $B$ is female.
7. Let's combine generation 2: $D$ is the father of $E$. Who is the mother? $B$ is a female. If $B$ is the mother of $E$, then $D$ and $B$ form a married couple.
8. This leaves $C$ and $A$ to be the other married couple. Since $F$ is the grandmother, $C$ and $A$ could be the grandparents' level or parent level. If $C$ and $A$ are married, and $F$ is already there, $F$ must be married to either $A$ or $C$? No, the text states "$C$ is married to $A$ ". This forms couple 1 ($C+A$). Thus, couple 2 must be $D+\text{someone}$. The remaining female is $B$. So $D$ is married to $B$.
9. Therefore, $B$ is the wife of $D$. Since $D$ is the father of $E$, $B$ is the Mother of $E$.
