Question

which characteristic is common among children who have older parents?
lower birth weight
higher social skills
greater average height
less access to preschool

Explanation:

To determine the common characteristic of children with older parents, we analyze each option:

• Lower birth weight: Older parents (especially mothers of advanced maternal age) may have a slightly higher risk of having a baby with lower birth weight due to various factors like potential health issues or placental problems, though it's not absolute.
• Higher social skills: There's no strong evidence that older parents' children have higher social skills; social skills are more related to upbringing, environment, and interactions rather than parental age.
• Greater average height: Parental age isn't a direct determinant of a child's height, which is more related to genetics, nutrition, and overall health.
• Less access to preschool: Older parents are often more established financially and may have better access to preschool or educational resources for their children.

So the most plausible option related to children of older parents is lower birth weight.

Answer:

A. lower birth weight
