A certain volume of dirt can cover sins aplenty. The equation to maximally obscure the past, originating in Working Papers on Management of Controlled But Uncultivated Spaces (1963), only addresses size, toxicity, and available time. This poses a land management question.
A certain number of detainees can be sustained by a certain amount of supplies. Debate continues over how much food and water obviate the need for handlers to allow their subjects sensory freedom. This poses a training question.
A certain hardness of spirit is necessary to accomplish the necessary. First- and second order necessities are necessarily bound to the third necessity, which is identifying bodies that calcify without cracking. This poses a human resources question.
A certain amount of money can remove someone from the world: that required to establish two shell companies, hire one trusted broker, and fill an average duffel bag with bills. This poses a finance question.
A certain chemical reaction can scrape city blocks clean. The precursors are easily acquired and easily transported, but not in the volumes needed to express dissatisfaction with the status quo. This poses a procurement question.

Keeping them, blind and deaf, affected but not affecting, and doing so across a lifetime of twists and turns, successes and failures, poses an existential question.
