Study the table carefully and answer the following questions:
| Machine | Load (N) | Effort (N) | Load Arm (m) | Effort Arm (m) |
| Lever A | \(300\) | \(100\) | \(0.5\) | \(1.5\) |
| Lever B | \(200\) | \(100\) | \(0.4\) | \(0.8\) |
| Inclined Plane C | \(500\) | \(250\) | - | - |
1. Which machine has the greatest mechanical advantage?
2. If the effort applied to Inclined Plane C is increased to \(300\ N\) while its mechanical advantage remains \(2\), what load can it lift?
