College Life

After settling into her first few days of classes, Molly headed to auditions for the school's a cappella groups. She was greeted by a panel of three college students.
"Welcome to auditions," the one in the center said. "Molly, right"
"Yeah, that's me."
"Awesome! Now, you have two choices for what group you want to audition for. You can audition for the mixed group, which has all voice types in it. Or you can audition for the treble group, which is just sopranos and altos."
