It's not subjective.
Read it again. It's fill-to-the-brim operations of one jug against the other, accepting as truth that one is 5 gallons to its upper limit, and the other is 3 gallons to its upper limit.
Pour 2/3 of 3 into 5, filling it and leaving 1 in 3.
...
Pour 1/3 of 3 into 5.
...
3/5 of 5 into 3.
...
Pour 2/5 of 5 into 3. You now have 2/3 of 3 filled.
Kinda hard to read your description as anything other than fractions when you say things like "pour 1/3 of 3 into 5".
At any rate...
The movie looks like it's gonna be fun.
Along the same lines, Disney just announced that J.J. Abrams will be helming the opening installment of an upcoming Stars Wars trilogy.
