Difficulty: MediumBlood Relations

Morgan and Jordan are the only children of their parents. Their father has exactly one sister, named Claire, and no brothers. If Claire's only niece is Morgan, what is the relationship of Jordan to Morgan?

Answer: brother / Brother / a brother

Answer

brother
Because Claire can only have one niece (Morgan), the other child in the family (Jordan) must be a nephew (male). Therefore, Jordan is Morgan's brother.

Step-by-Step Solution

1
Identify the relationship between Claire and the siblings.
Claire is the sister of Morgan and Jordan's father, making her their paternal aunt.
To establish the generational and relational link between the adult and the children.
2
Determine Morgan's gender based on relational constraints.
Morgan is female.
The term 'niece' strictly designates a female child of one's sibling.
3
Deduce Jordan's gender using the exclusivity condition.
Jordan must be male.
Claire has only one sibling (the children's father), so her only nieces or nephews are his children. Because Claire has exactly one 'only niece' (Morgan), the other child (Jordan) cannot be female.
4
Determine Jordan's relationship to Morgan.
Jordan is Morgan's brother.
Since Jordan is male and shares the same parents as Morgan, he is her brother.

Key Concept

Using exclusionary relationship terms to logically deduce gender without relying on names.
