2 真 则 drover-carter butler-hunter hunter-butler 那么 carter-drover 对
3 真 则 hunter-hunter 错误
4 真 则 carter-hunter butler-hunter 错误
所以， Mr Carter is the drover
从而得出结论，1.Mr Carter is the drover.
2.Mr Drover is the carter.
3.Mr Butler is the hunter.
4.Mr Hunter is the butler

Answer 2

1 真 则 carter-hunter butler-hunter hunter-butler 那么 drover-drover 所以不成立
2 真 则 drover-carter butler-hunter hunter-butler 那么 carter-drover 成立
3 真 则 hunter-hunter 不成立
4 真 则 carter-hunter butler-hunter 不成立
so Mr Carter is the drover
