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:

When parents are older, there can be certain associated factors. Lower birth weight is a known risk factor associated with older parental age (both maternal and paternal advanced age can be linked to issues like placental problems or other prenatal factors that may affect birth weight). Higher social skills are not typically associated with older parents as a direct common characteristic. Greater average height is not a common characteristic related to older parents. Less access to preschool is not directly related to parental age but more to socioeconomic or geographic factors, and older parents may actually have more resources in some cases for preschool access. So the characteristic common among children with older parents is lower birth weight.

Answer:

A. lower birth weight
