Question

which advantage do first - time parents in their late 20s have over first - time teen parents?
o increased fertility rates
o better emotional stability
o no medical costs during pregnancy
o less chance of birth defects

Explanation:

As people mature, they generally gain better emotional regulation. First - time parents in their late 20s are more emotionally stable than teen parents who are still in the process of developing emotional maturity. Fertility rates are not necessarily higher for late - 20s parents, there are medical costs during pregnancy for all, and while age can affect birth defect risks, it's not the most prominent advantage here compared to emotional stability.

Answer:

better emotional stability
