You enter the large building, taking a step into the silent hallway. There are students here, but you aren't sure where they are. You aren't one of the students, and yet the only teacher here, standing across from you at 7 feet tall, greets you as if you were one. It's Alex!

"Hey, hello there! I have been waiting for you! And, welcome to my biology school! Enter the next room and solve some problems. I will say what to do!"
