With no explanation, chose the best option from "A", "B", "C" or "D". By contrast, courts can bar future suits as a sanction to punish a refusal to pay past court costs and sanctions even if the litigant is indigent. The district court here did not impose a filing bar as a sanction against Gay but invoked only its power to order a bond for costs. The court erred when it ordered Gay to post a bond it knew he could not afford. The district court correctly reasoned that its authority to award costs to a prevailing party implies a power to require the posting of a bond reasonably calculated to cover those costs, even though no statute or rule expressly authorizes such an order. See Anderson v. Steers, Sullivan, McNamar & Rogers, 998 F.2d 495, 496 (7th Cir.1993) (affirming dismissal); Pedraza v. United Guaranty Corp., 313 F.3d 1323, 1335-36 (11th Cir.2002) (<HOLDING>); Simulnet East Assocs. v. Ramada Hotel
