WHICH STATEMENT BEST DESCRIBES THE SYSTEM DESCRIBED IN THIS SOURCE?
He who swears fealty (loyalty) to his lord ought always to have these six things in memeory , what is harmless, safe honorable, useful, easy, practicable (possible)... The lord also ought to act toward his faithful vassal reciprocally (mutually) in all these things. And if he does not do this he will be justly considered guilty of bad faith, just as the former, if he should be detected in the avoidance of or the doing of or the consenting to them, would be perfidious(disloyal)
