Hot, moist tropical rain forests have high evapotranspiration rates, which creates a lot of moisture in the air. This results in a high relative humidity, meaning that the air is holding a significant amount of water vapor compared to its maximum capacity at a given temperature. Specific humidity refers to the actual amount of water vapor in the air, and while it may be relatively high above rain forests, it is not the best choice because it doesn't necessarily describe how much water vapor the air could hold. Saturation vapor pressure is the pressure exerted by water vapor when it is in equilibrium with its condensed phase (e.g. in a cloud or on a surface). While the saturation vapor pressure may be high above rain forests due to the high water vapor content of the air, it is not the best choice because it doesn't necessarily describe the humidity itself or how close the air is to saturation. Finally, while evaporation rates may be high above rain forests due to the warm temperatures and abundant surface moisture, it is not the best choice because it describes a physical process of water leaving a surface rather than the moisture content of the air itself.
