Mr. Mendez says, “I think you’ll manage” to Will when he is obviously floundering. Why? Has anyone ever let you struggle to figure something out yourself? How did you feel once you had done it?

I'm confused but, I'll try. I think this pertains to whoever is answering so..

Explanation:

Mr. Mendez says this to Will because he thinks he needs to figure out something on his own instead of asking him. Yes, one time I asked my mom was I adopted. She never answered. That made me ponder. I asked every day she never answered. Now I finally know realizing that she was old enough to be my grandma. Once I found out she told me the horrible story of why I was in need of being adopted. Pretty scary...

d. everyone should be treated fairly.

it is definitely false.
