The mechanical advantage of the block and pulley you are using, or the engine of the fork lift truck if that is what you are using.
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
The more pulleys and ropes you add the easier it is to lift
which requires more energy, pulling a load, lifting, or pushing a load?
That's actually only possible in a First Class lever. In that case, moving the fulcrum closer to the load makes it easier to lift the load, since it now takes less force at the effort end. But the effort force also has to move through a greater distance than it did before, in order to lift the load to the same height.
The number of pulleys needed to lift a load varies based on the size of the load. A very small load can be lifted with just one pulley while large loads may require many pulleys to adequately lift the load.
If become easier to lift a load in a wheelbarrow when the load is towards wheel why

Leverage. The longer the handle, the easier it is to lift the load.

What is the weight and dimensions of the intended load? What is the heighth of lift?
It is a system of ropes and wheels that achieve the purpose of making an object easier to lift.
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required
