###### Problem Details

Blocks A and B have 300 and 200 oscillators, respectively. The blocks are placed in contact with each other in an insulated environment. At the instant the blocks touch, block A has 99 quanta of energy while block B has 1 quanta of energy. What will happen sometime after contact?

I. The entropy of block A will increase.
II. The entropy of block B will increase.
III. The entropy of the two-block system will increase.
