Explanation: Statement (1) is insufficient: the amount of water currently in the bucket doesn't tell us the capacity of the bucket. Statement (2) is sufficient: an increase of (1/3) when the bucket is half full is given by: (1/3)((1/2)x) = (1/6)x, where x is the capacity of the bucket. If (1/6)x = 3, we can solve for x, the capacity of the bucket. Choice (B) is correct.
