Rifle Discharge

Anderson, Biggs, and Carpenter were staying together at a place by the seaside. One day they went out in a boat and were a mile at sea when a rifle was fired on shore in their direction.

It seems that Anderson only heard the report of the gun, Biggs only saw the smoke, and Carpenter merely saw the bullet strike the water near them. Which of them first knew of the discharge of the rifle?

Riddle Answer

Five Jealous Husbands

During certain local floods five married couples found themselves surrounded by water, and had to escape from their unpleasant position in a boat that would only hold three persons at a time.

Every husband was so jealous that he would not allow his wife to be in the boat or on either bank with another man (or with other men) unless he was himself present.

Show the quickest way of getting these five men and their wives across into safety. Call the men A, B, C, D, E, and their respective wives a, b, c, d,e. To go over and return counts as two crossings. No tricks such as ropes, swimming, currents, etc., are permitted.
