Question: Why should we hook the emergency and air lines up before we back up under a trailer, as stated in #57?
They didn't teach me this in school, but if this question is correct according to DOT, then that's fine.

[@AlexTruckUS]

You must lock the trailer brakes before backing beneath the trailer, which requires that you first confirm that the trailer brakes are operating. After testing the trailer brakes, connect the emergency and service airlines.

[@____AFGHAN_______BOY]

Is number 33 is correct ?

[@AlexTruckUS]

The trailer hand valve should be used only to test the trailer brakes. Do not use it in driving because of the danger of making the trailer skid. The foot brake sends air to all of the brakes on the vehicle (including the trailer(s)).
