According to Our Town, what is the second act of life?

1) Daily Life

2) Love and Marriage

3) High School Graduation

4) Childbirth

According to my sources, i am pretty sure that it is 2), love and marriage, it also makes some since because daily life would come first because you need to do daily tasks to survive, then marriage would come second because usually you are married before child birth and high school isn't really mandatory.
