$3$. The son of her mother is her brother.
$4$. Therefore,the boy is the girl's brother.

(C) The phrase "only son of my grandfather" refers to the woman's father.
Since the man's brother's father is the same as the man's father,we have: Man's father = Woman's father.
This implies that the man and the woman are siblings.
Therefore,the woman is the sister of the man.

(B) $1$. Analyze the phrase 'my father's only son': Since the girl is speaking,her father's only son is her brother.
$2$. Analyze the phrase 'grandmother of my brother': This is the girl's grandmother.

(A) and $B$ are a married couple.
Since $X$ and $Y$ are brothers,and $X$ is the brother of $A$,it follows that $Y$ is also the brother of $A$.
Since $A$ and $B$ are married,the brother of $A$ $(Y)$ is the brother-in-law of $B$.

(D) and $B$ are brothers.
$A$'s son is $D$'s brother,which means $D$ is the daughter of $A$.
Since $C$ and $D$ are sisters,$C$ is also the daughter of $A$.
$B$ is the brother of $A$,and $C$ is the daughter of $A$.
Therefore,$B$ is the uncle of $C$.

(D) $1$. $A$ and $C$ are a married couple. Since $C$ is not the mother of $B$,$C$ must be the father and $A$ must be the mother. Thus,$A$ is female and $C$ is male.
$2$. $B$ is the son of $C$,so $B$ is male.
$3$. $E$ is the brother of $C$,so $E$ is male.
$4$. $D$ is the daughter of $A$,so $D$ is female.
$5$. $F$ is the brother of $B$,so $F$ is male.
$6$. Listing the members: $A$ (female),$B$ (male),$C$ (male),$D$ (female),$E$ (male),$F$ (male).
$7$. The male members are $B, C, E,$ and $F$. Therefore,there are $4$ male members in the family.

(D) $1$. Given that $A$ and $C$ are a married couple.
$2$. $B$ is the son of $C$,but $C$ is not the mother of $B$.
$3$. Since $C$ is the father of $B$ and $A$ is the spouse of $C$,$A$ must be the mother of $B$.
$4$. Therefore,$A$ is the mother of $B$.

(C) $1$. $A$ and $C$ are a married couple.
$2$. $B$ is the son of $C$ and $C$ is not the mother,so $C$ must be the father and $A$ must be the mother.
$3$. $B$ is the son of $A$ and $C$.
$4$. $D$ is the daughter of $A$ (and $C$).
$5$. $F$ is the brother of $B$,which means $F$ is also the son of $A$ and $C$.
$6$. Therefore,the children of $A$ are $B, D,$ and $F$.
$7$. Thus,$A$ has $3$ children.

(D) $1$. From the given information,$A$ and $C$ are a married couple. Since $B$ is the son of $C$ and $C$ is not the mother of $B$,$C$ must be the father and $A$ must be the mother of $B$.
$2$. $D$ is the daughter of $A$,and $F$ is the brother of $B$. Thus,$A$ and $C$ are the parents of $B, D,$ and $F$.
$3$. $E$ is the brother of $C$. The information provided does not mention anything about the marital status or the wife of $E$.
$4$. Therefore,the wife of $E$ cannot be determined from the given data.

(D) $1$. Given that $A$ and $C$ are a married couple. Since $C$ is not the mother of $B$ but $B$ is the son of $C$,$C$ must be the father and $A$ must be the mother.
$2$. $D$ is the daughter of $A$. Thus,$D$ is female.
$3$. $E$ is the brother of $C$,so $E$ is male.
$4$. $F$ is the brother of $B$,so $F$ is male.
$5$. $B$ is the son of $C$,so $B$ is male.
$6$. The females in the family are $A$ (mother) and $D$ (daughter).
$7$. Therefore,the pair of females is $(A, D)$.

(C) and $C$ are a married couple. Since $C$ is not the mother of $B$,$C$ must be the father of $B$.
Since $A$ and $C$ are married,$A$ is the mother of $B$.
$D$ is the daughter of $A$,which means $D$ is also the daughter of $C$.
$E$ is the brother of $C$.
Since $E$ is the brother of $D$'s father $(C)$,$E$ is the paternal uncle of $D$.

(A) is the son of $B$.
$C$ is the sister of $B$.
$D$ is the son of $C$.
Since $A$ is the son of $B$ and $D$ is the son of $B$'s sister $(C)$,$A$ and $D$ are children of siblings.
Therefore,$A$ is the cousin of $D$.

(C) is the sister of $B$. $D$ and $E$ are the children of $C$.
Since $F$ is the maternal uncle of $D$,$F$ is the brother of $C$.
Because $E$ is the daughter of $C$ and $F$ is the brother of $C$,$F$ is the maternal uncle of $E$.
Therefore,$E$ is the niece of $F$.

(C) $1$. $F$ is the maternal uncle of $D$,which means $F$ is the brother of $D$'s mother,$C$.
$2$. $C$ is the sister of $B$. Therefore,$F$ is also the brother of $B$.
$3$. $A$ is the son of $B$. Since $F$ is the brother of $B$,$F$ is the maternal uncle of $A$.
$4$. $D$ is the son of $C$. Since $F$ is the brother of $C$,$F$ is the maternal uncle of $D$.
$5$. Both $A$ and $D$ are the nephews of $F$. Thus,$F$ has two nephews.

(C) is the sister of $B$. $D$ and $E$ are the children of $C$. Therefore,$D$ and $E$ are siblings.
$F$ is the maternal uncle of $D$. Since $D$ and $E$ are siblings,$F$ is also the maternal uncle of $E$.
Thus,$F$ is the maternal uncle of $E$.

(D) Given that $Q$ and $R$ are sisters. Since $T$ is the mother of $R$,it follows that $T$ is also the mother of $Q$.
$S$ is the son of $T$,which implies that $S$ is the brother of $Q$ and $R$.
$P$ is the son of $Q$. Since $S$ is the brother of $Q$ (the mother of $P$),$S$ is the maternal uncle of $P$.

(D) $P$,$Q$,and $R$ are siblings because $P$ is the brother of $Q$ and $R$.
Since $S$ is the mother of $R$ and $T$ is the father of $P$,$S$ and $T$ are the parents of $P$,$Q$,and $R$.
We know $P$ is male (brother),but the gender of $Q$ is not specified in the problem statement.
Therefore,we cannot definitely conclude that $Q$ is a son; $Q$ could be a daughter.
Thus,the statement "$Q$ is the son of $T$" cannot be definitely true.

(A) It is given that $A$ and $B$ are both children of $C$.
Since $C$ is the mother of $A$ and $A$ is the son of $C$,$A$ is male.
It is stated that $B$ is a child of $C$ but not the daughter of $C$.
Since $B$ is a child of $C$ and not a daughter,$B$ must be the son of $C$.
Therefore,both $A$ and $B$ are sons of $C$,which makes $A$ the brother of $B$.

(D) is the daughter of $B$ and $D$ is the son of $B$. Therefore,$D$ and $C$ are siblings,specifically $D$ is the brother of $C$.
$E$ is married to $C$. Since $E$ is the son of $A$ (male),$E$ is the husband of $C$.
Since $D$ is the brother of $E's$ wife $(C)$,$D$ is the brother-in-law of $E$.

(B) Let the boy be $B$ and the woman be $W$.
$B$'s maternal uncle is the brother of $B$'s mother.
Let $M$ be the mother of $B$. The maternal uncle of $B$ is $U_1$.
According to the statement,the maternal uncle of $W$ $(U_2)$ and the maternal uncle of $U_1$ $(U_3)$ are brothers.
Since $U_1$ is the brother of $M$,the maternal uncle of $U_1$ $(U_3)$ is the same as the maternal uncle of $M$.
If $U_2$ and $U_3$ are brothers,and $U_2$ is the maternal uncle of $W$,then $W$ must be the daughter of $M$.
Therefore,the boy $B$ is the son of the woman $W$.

(B) $1$. $A$ is the brother of $F$,and $F$ is the daughter of $D$. Therefore,$A$ is the son of $D$.
$2$. $P$ is the brother of $D$.
$3$. Since $P$ is the brother of $A$'s parent $(D)$,$P$ is the uncle of $A$.

(D) Given that $P$ is the mother of $X$.
$X$ is the wife of $Z$.
Since $X$ is the daughter of $P$ and $X$ is married to $Z$,$P$ is the mother of $Z$'s wife.
Therefore,$P$ is the mother-in-law of $Z$.

(B) $Q$ is the husband of $P$,which implies $P$ is the wife of $Q$.
$Y$ is the brother of $P$.
Since $Y$ is the brother of $P$ and $P$ is the wife of $Q$,$Y$ is the brother of $Q$'s wife.
Therefore,$Y$ is the brother-in-law of $Q$.

(A) $P$ is the mother of $X$.
Since $X$ is the wife of $Z$,$X$ is female.
$Q$ is the husband of $P$.
Since $P$ is the mother of $X$ and $Q$ is the husband of $P$,$Q$ is the father of $X$.
Therefore,$X$ is the daughter of $Q$.

(A) $P$ is the mother of $X$,and $X$ is the wife of $Z$. This means $P$ is the mother-in-law of $Z$.
Since $Q$ is the husband of $P$,$Q$ is the father-in-law of $Z$.

(D) $1$. We are given that $E$ is the unmarried engineer.
$2$. $F$ is the son of $B$ and the brother of $E$. This implies $E$ and $F$ are siblings.
$3$. $C$,the lawyer,is the daughter-in-law of $A$. Since $A$ is the grandmother of $F$,$C$ must be the mother of $F$ and $E$.
$4$. $B$ is the father of $F$ and $E$. Since $C$ is the mother,$B$ and $C$ form a married couple.
$5$. The doctor is married to the lawyer $(C)$. Therefore,$B$ is the doctor.
$6$. There are two married couples. The other couple is $A$ and $D$. $D$ is the salesman and is married to the lady teacher $(A)$.
$7$. Since $F$ and $E$ are children of $B$ and $C$,and $E$ is the brother of $F$,$E$ is either the brother or sister of $F$. However,the gender of $E$ is not specified in the problem statement.
$8$. Therefore,the relation between $E$ and $F$ cannot be determined.

(B) $1$. $E$ is the unmarried engineer.
$2$. $C$ is the lawyer and the daughter-in-law of $A$. Since $A$ is the grandmother of $F$ and $F$ is the son of $B$,$C$ must be the mother of $F$ and the wife of $B$.
$3$. The doctor is married to the lawyer $(C)$. Therefore,$B$ must be the doctor.
$4$. $D$ is the salesman and is married to the lady teacher. Since $A$ is the grandmother of $F$,$A$ and $D$ form the other married couple,where $A$ is the lady teacher and $D$ is the salesman.
$5$. Thus,$B$ is the doctor.

(B) $1$. $E$ is the unmarried engineer.
$2$. $C$ is the daughter-in-law of $A$,and $A$ is the grandmother of $F$. This implies $C$ is the mother of $F$.
$3$. $F$ is the son of $B$,so $B$ is the husband of $C$.
$4$. The doctor is married to the lawyer. Since $C$ is the lawyer,$B$ must be the doctor.
$5$. There are two married couples. The second couple must be $A$ and $D$.
$6$. $D$,the salesman,is married to the lady teacher. Since $A$ is the grandmother of $F$,$A$ must be the lady teacher.
$7$. Therefore,$A$ is the teacher.

(D) $1$. $E$ is the unmarried engineer.
$2$. $C$ (lawyer) is the daughter-in-law of $A$. Since $A$ is the grandmother of $F$ and $F$ is the son of $B$,$B$ and $C$ must be a married couple.
$3$. The doctor is married to the lawyer $(C)$. Since $C$ is the lawyer,$B$ must be the doctor.
$4$. $D$ (salesman) is married to the lady teacher. Since $A$ is the grandmother of $F$ and the only remaining female is $A$,$A$ must be the lady teacher.
$5$. Thus,the two married couples are $(B, C)$ and $(D, A)$.
$6$. Comparing this with the options,none of the given pairs $(F, D)$,$(D, B)$,or $(E, A)$ are married couples.

(A) Given $E$ is the unmarried engineer. $C$ is the daughter-in-law of $A$,who is the grandmother of $F$,which means $C$ is the mother of $F$. Since $F$ is the son of $B$,$B$ must be the husband of $C$. The lawyer $(C)$ is married to the doctor,so $B$ is the doctor. $F$,the accountant,is the son of $B$ and $C$. The other married couple must be the grandparents of $F$,which are $A$ and $D$. Since $D$,the salesman,is married to the lady teacher,$D$ is the grandfather of $F$,the father of $B$,and the husband of $A$,the lady teacher. Therefore,$D$ is the grandfather of $F$.

(B) $Q$ is the son of $R$ but $R$ is not the mother. Therefore,$R$ is the father of $Q$.
$P$ and $R$ are a married couple,so $P$ is the wife of $R$ and the mother of $Q$.
$X$ is the daughter of $P$,which means $X$ is also the daughter of $R$ and the sister of $Q$.
$Y$ is the brother of $R$.
$Z$ is the brother of $P$.
Since $R$ is the husband of $P$ and $Z$ is the brother of $P$,$Z$ is the brother-in-law of $R$.

(C) $Q$ is the son of $R$,but $R$ is not the mother of $Q$. Since $R$ is a parent and not the mother,$R$ must be the father of $Q$.
$P$ and $R$ are a married couple. Since $R$ is the father,$P$ must be the mother of $Q$.
$X$ is the daughter of $P$,which means $X$ is also the daughter of $R$.
$Y$ is the brother of $R$ and $Z$ is the brother of $P$.
Therefore,the father of $Q$ is $R$.

(C) $Q$ is the son of $R$ but $R$ is not the mother of $Q$. Since $R$ is a parent and not the mother,$R$ must be the father of $Q$.
$P$ and $R$ are a married couple. Since $R$ is the father,$P$ must be the mother of $Q$.
$X$ is the daughter of $P$. Since $P$ is the mother of $Q$,$X$ is also the daughter of $P$ and $R$.
$Y$ is the brother of $R$ and $Z$ is the brother of $P$,which are relatives of the parents.
Therefore,the children of $P$ are $Q$ (son) and $X$ (daughter).
Thus,$P$ has $2$ children.

(B) $Q$ is the son of $R$,but $R$ is not the mother. Therefore,$R$ is the father of $Q$.
$P$ and $R$ are a married couple. Since $R$ is the father,$P$ must be the mother of $Q$.
$X$ is the daughter of $P$,which makes $X$ a female member.
$Y$ is the brother of $R$ (male).
$Z$ is the brother of $P$ (male).
$Q$ is the son of $R$ (male).
Thus,the female members in the family are $P$ (mother) and $X$ (daughter).
There are $2$ female members in the family.

(B) $Q$ is the son of $R$,but $R$ is not the mother. Therefore,$R$ must be the father of $Q$.
$P$ and $R$ are a married couple. Since $R$ is the father,$P$ is the mother of $Q$.
$X$ is the daughter of $P$,which means $X$ is also the daughter of $R$.
Since $Q$ is the son of $R$ and $X$ is the daughter of $R$,$Q$ and $X$ are siblings.
As $Q$ is the son (male),$Q$ is the brother of $X$.

(A) $Q$ is the son of $R$ but $R$ is not the mother. Therefore,$R$ is the father of $Q$.
$P$ and $R$ are a married couple. Since $R$ is the father,$P$ must be the mother of $Q$.
$X$ is the daughter of $P$,which means $X$ is the sister of $Q$.
$Y$ is the brother of $R$. Since $R$ is male (father),$Y$ and $R$ are brothers.
$Z$ is the brother of $P$. Since $P$ is female (mother),$Z$ is the brother of $P$.
Thus,the pair of brothers is $Y$ and $R$.

(C) $Q,$ the doctor,is the father of $T.$ $S,$ the housewife,is the grandmother of $T$ and hence the mother of $Q.$ Since there are only two married couples,one being that of $Q,$ the grandfather of $R,$ i.e.,$U,$ must be married to $S.$ Thus,$R$ and $T$ are the children of $Q$ and are the students. $P,$ who remains,must be the wife of $Q$ and is the nurse. Therefore,the husband of $P$ is $Q.$

(A) $Q$ (doctor) is the father of $T.$ $S$ (housewife) is the grandmother of $T,$ which implies $S$ is the mother of $Q.$
Since there are two married couples,and one is $Q$ and his wife,the other couple must be $U$ (grandfather of $R$) and $S.$
Thus,$U$ and $S$ are the first couple,and $Q$ is married to $P.$
Since $Q$ is the father of $T$ and $U$ is the grandfather of $R,$ $R$ and $T$ are children of $Q$ and $P.$
$R$ and $T$ are the two students.
$P$ must be the nurse.
Since $R$ and $T$ are siblings and $R$ is the only other child besides $T,$ $R$ is the sister of $T.$

(B) $Q$ (doctor) is the father of $T.$ $S$ (housewife) is the grandmother of $T,$ which implies $S$ is the mother of $Q.$ Since there are two married couples,and $U$ is the grandfather of $R,$ $U$ must be the husband of $S.$ Thus,$U$ is the contractor. $Q$ and his wife $P$ form the second married couple. $R$ and $T$ are the children of $Q$ and $P,$ and they are the two students. Since $P$ is the only remaining member,she must be the nurse.

(B) $Q$,the doctor,is the father of $T$.
$S$,the housewife,is the grandmother of $T$ and hence the mother of $Q$.
Since there are only two married couples,one being that of $Q$,the grandfather of $R$,i.e.,$U$,must be married to $S$.
Thus,$R$ and $T$ are the children of $Q$ and these must be the students.
$P$,who remains,must be the wife of $Q$ and she is the nurse.
Therefore,the two married couples are $(Q, P)$ and $(U, S)$.
