Essays / Essay about The Fountainhead by Ayn Rand [2]

Can someone kindly help me with this question given to me from my teacher, especially the second part?
I have no idea what I should write. Thank you!!

How does Howard Roark exemplify the fact that reason must be used to solve man's problems, rather than relying on others' judgments or one's emotions? Why is the dynamiting of Cortlandt not an example of irrationality?

Essays / SURGERY SCAR; Overcoming Hardships Essay [2]

I didn't write my essay yet, but I have a topic in mind. I wanted to talk about this surgery scar I have ever since I was a little baby because of a heart condition/disease.

But the thing is, I don't know where the essay will "lead to". I don't know if I should say something like "I learned not to care when others look at my scar", but that sounds so common and unoriginal.

I know I'm not really being specific, but can someone guide me through this?
Thanks!
