Given the constraint of 48 hours per week and a half-time devotion (4 hours per day), the first week requiring resource leveling is when the combined hours exceed the weekly limit. Activity A starts first and alone, fitting within the limit. Activities B and C start after A, but C requires 5 hours per day, leading to a potential overlap with B's start. However, the critical point is when B, requiring 11 days at 4 hours per day, overlaps with F's start, which requires 6 hours per day. This overlap occurs in week 4, as B starts immediately after A, and F starts after B, leading to a combined requirement that exceeds the 48-hour weekly limit.
