Hold up, I've got a better idea. Why not just set it to over 9000? That's gotta be the answer, right? Haha!

I'm not sure about this one. I'd say C, just to be safe. You don't want to overload the system with too many reducer tasks, right?

I think the answer should be D. It makes sense to have the same number of reducer tasks as the number of input files.

But setting it to 4 would allow for parallel processing and faster execution.
