*Die Hard:* At the fountain there are two strange shaped
jugs. Their capacities are 5 gallons and 3 gallons. You must fill one of
the jugs with exactly 1 gallon and place it on the scale two prevent a bomb
from exploding. You must be perfectly precise and no other tools are allowed
(Simon is watching). The lives of thousands are in your hands (and brains).

How about if you were give 5- and 7- gallon jugs but still needed to measure
exactly 1 gallon?

What about 4- and 6- gallon jugs?
