Ling is devising a checklist to predict a female child's reaching puberty early. which is not a question he should include in his list?

I found the exercise on the internet and these were the options:
"A)Did this girl grow up in a single-parent mother-headed family?
B)Was this girl insecurely attached?
C)Did this girl have a stressful childhood?
D)Does this girl have many siblings?"

Correct D
The number of siblings is not a factor that promotes early puberty in girls. All the other factors do have an impact although the mechanisms are yet not very well known. When there is not a father figure present, girls tend to reach puberty earlier. When they are insecurely attached to their mother, girls also tend to reach puberty earlier. Lastly, another factor that may lead to an earlier puberty in girls is the stress they've passed through during childhood - mostly from family conflicts, whether with parents or siblings.
