According to your textbook, what kind of reasoning is used in the following statement? u. s. children raised in two-parent families with incomes below the poverty line have a greater incidence of school absences, lower test scores, and less chance of finishing high school than do children raised in one-parent households with incomes at least 10 percent above the poverty line. we can see, therefore, that it is the economic stability of the family, not its family structure, that determines a child's ability to succeed in school.
