If you have a 3 gallon cylindrical shaped jug and a 5 gallon cylindrical shaped jug with an unlimited supply of water (and no other containers), which is the correct procedure to end up with exactly 4 gallons in the 5 gallon jug?	
	a. Fill 3 gallon jug. Pour out half of the 3 gallon jug by
	b. Fill 3 gallon jug. Pour it all into the 5 gallon jug twice
	c. Fill 5 gallon jug. Pour all but 2 gallons into the 3 gallon jug
	d. All of the above	
	e. None of the above

Procedure c would work, but it requires more steps. So the answer can also be "None of the above".
The extra steps are as follows:
- Empty the 3 gallon jug and pour the 2 gallons in the 5 gallon jug into it. Now there is 1 gallon free in the 3 gallon jug.
- Fill the 5 gallon jug. Pour all but 4 gallons into the 3 gallon jug.

how long would it take me to fill up my pond if i have 3 gallon jugs and i can only take 1 at a time it takes me about 45 secconds to fill it up but it takes about 4 minites to get it from my sink out in the backyard to where my pond is, by the time i make it to the pond its only half full it takes me only about 15 secconds to dump it out into the pond so if i didnt rest untill it was full how long would it take to fill up a 300 gallon pond this way?
