Summary

For both C and S, if a prisoner tries to escape from their sector, C and S must leave their respective stations to pursue the prisoner.

If they are not pursuing an escaped prisoner, C and S cannot leave their stations until their replacements have arrived.

On May 11 at 9pm, C and S finished a four-hour shift and their replacements arrived at the end.

C had violated the rules described. S had not violated the rules described.

Notable Valid Inferences

There’s no clear inference to draw, because there are many ways in which C could have violated the rules and S would not violate the rules. Let’s use process of elimination to identify what must be false.
