The first question, they let you describe again why you apply NIW. Why does your project benefit USA in National scope. Did you answer this question clearly? It is not proved that how you are excellent, but also how important for USA.
The second question is a tricky one. You need prove how unique you are. How outstanding you are is for EB1a, now exactly NIW. It means why you don't apply PERM? Outstanding is very important, but also you need prove why other qualified researcher is not as good as you, and why they cannot contribute more than you did.
