What statements are true for the Hydrophobic Effect.

Question

1/ The system increases the solvent-exposed area of non-polar parts, which makes more water molecules bound to the hydrophobic regions.

2/ The system makes the solvent-exposed area of non-polar parts smaller, which reduces the number of ordered water molecules. The fled water molecules become free to move, thereby increasing ΔS. As a result, the non-polar region of the molecules clusters together.

3/ The system makes the solvent-exposed area of non-polar parts smaller, which reduces the number of ordered water molecules. The fled water molecules become free to move, thereby increasing ΔH. As a result, the non-polar regions of the molecules clusters together.

4/ Non-polar solutes have a propensity to come together, which is the driving force to exclude water molecules from them.

I personally think, 2 is correct and but 3 and 4 are, I don't understand.
does enthalpy have anything to do with the system reaction and the 4?
