This question is discussed here.

Anyway for your benefit. This is a number properties question.

1) n = (k+1)^3
Let's take k = 2
then n = 27, remainder = 1
k = 3, then n = 64, remainder = 1
k = 4, n = 125, remainder = 1
Remainder is always 1. Sufficient.

2) Clearly insufficient. We know nothing about N.
