The baby-boom that followed world war ii later contributed to which of the following? a)expanding job opportunities in the 1980s b)dramatic increase in elementary school enrollment in the 1970s c) increase in social security collections in the 1950s d)creation of a youth culture in the 1960s

B - Dramatic Increase in Elementary School Enrollment in the 1970's

A is incorrect as job opportunities are not proportionate to birth rate.

C is incorrect as social security collections do not occur until you are of age - 62.

D is incorrect as the youth culture is always created with whatever youth is present - it's mostly referred to as the young culture or kids culture more than anything and would not be created only because of a baby boom.

Hope this helps!
