Big City High School has had a very high rate of pregnancy among its students. In order to assist students who keep their babies to complete high school, Big City High School has established an infant day-care center for children of its students, and also offers classes in child-care. Because the child-care classes are always overcrowded, the school limits admission to those classes solely to Big City High School students who are the mothers of babies in the infant day-care center. Joe, a student at Big City High School, has legal custody of his infant son. The school provides care for his son in its infant day-care center, but will not allow Joe to enroll in the center, but will not allow Joe to enroll in the child-care classes. He brings suit against the school challenging, on constitutional grounds, his exclusion from the child-care classes. Which of the following best states the burden of persuasion in this case? 
Joe must demonstrate that the admission requirement is not rationally related to a legitimate governmental interest. Joe must demonstrate that the admission requirement is not as narrowly drawn as possible to achieve a substantial governmental interest. The school must demonstrate that the admission policy is the least restrictive means by which to achieve a compelling governmental interest. The school must demonstrate that the admission policy is substantially related to an important governmental interest.
