In the abatement process, which class is last to abate?

• A. Residual
• B. General
• C. Specific and demonstrative
• D. Demonstrative

Answer: (C)

Abatement work is done in a progression from broad, general mitigation to the most specific, evidence-backed actions. You begin with the larger, residual and general aspects because they set the baseline and remove the easiest-to-address portions of the problem. Once those broad elements are under control, you move into targeted tasks that address precise locations or particular elements. The final phase combines targeted, location-specific actions with demonstrative evidence that proves to stakeholders what was accomplished. Those specific and demonstrative steps rely on having completed the earlier work and producing concrete proof of completion, so they are done last.
