A demographic research algorithm maps family lineages using the following logical operators:

• $X \nabla Y$ means $X$ is the legally recognized spouse of $Y$ .
• $X \Delta Y$ means $X$ is the biological mother of $Y$ .
• $X \Omega Y$ means $X$ is the sibling of $Y$ .
• $X \Sigma Y$ means $X$ is the child of $Y$ .

Based strictly on the relational sequence $H \Sigma G \nabla F \Delta E \Omega D$ , which of the following conclusions is logically definitive?

A
H is the brother of E.
B
E is the sister of H.
G is the father of D.Answer
D
D is the son of F.

Answer

G is the father of D.

The sequence establishes that F is the mother of E, and E is the sibling of D, making F the mother of D as well. Because G is the spouse of F, G is definitively male and thus the father of F's children. Consequently, G is definitively the father of D.

Step-by-Step Solution

Analyze the relationship

F \Delta E

and

E \Omega D

F

is the mother of

E

, and

E

is the sibling of

D

. Therefore,

F

is also the mother of

D

To establish the maternal lineage for the right side of the sequence.

Analyze the relationship

G \nabla F

G

is the spouse of

F

. Since

F

is a mother (female),

G

must be male.

To determine the gender and parental role of

G

Combine the findings for

G

F

, and

D

G

is the husband of

F

, and

F

is the mother of

D

. Therefore,

G

is definitively the father of

D

To identify the exact relationship between the male spouse and the children.

Evaluate the genders of

H

E

, and

D

The operators

\Sigma

(child) and

\Omega

(sibling) do not assign a gender. Thus, the exact genders of

H

E

, and

D

remain unknown.

To eliminate any conclusions that make assumptions about unstated genders.

Key Concept

Deducing exact kinships and avoiding gender assumptions in coded relationships.
