Parent State ID: 7
State Depth: 4
Action Taken: stack(a, c)
Action Reasoning: The goal is to place block c on block a. Since the hand is currently holding block a and block c is clear, I will stack block a on block c to prepare for the next step.
State Description: Block a is on top of block c. Block b is on the table and clear. Block d is on the table and clear. Block c is no longer clear. The hand is empty.
Action Path: ['unstack(d, c)', 'put-down(d)', 'unstack(a, b)', 'stack(a, c)']
