What conclusion follows logically from the quoted definition of family?
We are asked what must be true according to the definition
"A family is a household containing a householder and at least one person related to the householder."Note that this bureaucratic definition deviates from conventional usages of the term "family."
The definition mentions only families, households, and householders
–not the homeless or people in group living quarters.
The subsequent explanatory comment suggests that
the homeless and people in group living quarters generally are not members of "householdswhich implies that the quoted definition of "family" typically doesn't apply to them.
A According to the definition,
a householder living alone or in a household whose members are all unrelated to each other is not a member of a "family."
- WrongB
Correct.
The definition explicitly states that a
Family: is a household including a householder along with at least one relative of the householder.
It follows logically from this definition that every "family" includes a householder.
C According to the definition,
people related to a householder but living in different households do not form a "family."
- WrongD The quoted definition says nothing about people living in group living quarters.
The explanatory statement after the definition implies that
Residents sharing group living quarters do not constitute a "household," which suggests that they do not constitute a "family" either according to the quoted definition
- WrongE The quoted definition neither says nor implies anything about where homeless people reside
- Wrong The correct answer is B.
