Q. According to the rules, D can marry

Detailed Solution for Test Level 3: Blood Relations - Question 7


We can draw the above diagram based on the information given in the question. If the gender of the person is known, it is denoted by the suffix m or f. If it is not known, then it is denoted by x or y. We know, for example, that G is of the same sex as C, so we can label both as x; B and therefore, F are of the opposite sex from C, so we can label both y, and so on. Horizontal lines indicate marriage, vertical or diagonal lines indicate children. 
D is an x, and can therefore, marry any unmarried y. So, he can marry F, J, or K. 
Hence, answer option (1) is correct.

E and E's spouse, I, have two children J and K, who are of the same sex as I.
No person has married more than once, and no children have been born out of wedlock.
The only restriction on marriage is that marriage to a sibling, to a direct descendant, or to more than one person at the same time is forbidden.

Q. F is

Detailed Solution for Test Level 3: Blood Relations - Question 8


We can draw the above diagram based on the information given in the question.
If the gender of the person is known, it is denoted by the suffix m or f. If it is not known, then it is denoted by x or y. We know, for example, that G is of the same sex as C, so we can label both as x; B and therefore, F are of the opposite sex from C, so we can label both y, and so on.
Horizontal lines indicate marriage, vertical or diagonal lines indicate children.  
This question orients you, in case you made an unwarranted assumption about the sexes. Since we do not know B's sex for sure, we cannot determine F's as well; this rules out all the wrong choices - including E, since we know H's sex.
Being the child of D's sibling, B, F is D's niece or nephew. 
Therefore, option 2 is the correct answer.
