What provision provides reduced benefits to an individual who is partially able to work after receiving full disability benefits?

The correct choice is associated with provisions designed for individuals who experience a reduction in their ability to work due to a disability. Residual disability refers specifically to situations where an individual is partially disabled but still able to perform some work. In this case, the individual may receive reduced benefits that are proportional to their ability to work.

For example, if a person originally qualified for full disability benefits but later returns to work part-time or in a limited capacity, residual disability provisions allow them to receive benefits that supplement their earnings based on their reduced capacity. This is particularly beneficial because it encourages individuals to return to work without losing their entire disability benefits, offering financial support while they transition back to full employment.

The other options do not accurately capture this specific situation. Short-term disability typically refers to temporary benefits provided during a brief period of total disability. Supplemental income generally addresses additional income that may assist beyond basic benefits but does not specifically pertain to partial work ability. Temporary total disability relates to situations where an individual is entirely unable to work for a limited timeframe, which does not apply here.
