Step 1: Identify Initial State. Begin by identifying the initial state of all objectives (e.g., who holds which ball or who is dancing with whom) from the input text before any swaps happen.
Step 2: Identify the sequences of swaps from the input text. Each swap should be understood in terms of who exchanges with whom.
Step 3: Begin tracking changes throughout the swap sequences.
Step 4: Carry out the swaps. For each swap, sequentially update the current status of objectives by exchanging them between the two participants involved in the swap.
Step 5: Understand the Question. After processing all swaps, identify what the question is asking for in the input text.
Step 6: Analyze Options. Examine the provided options in the input text.
Step 7: Determine the Correct Option. Using the updated state after all swaps, determine which option correctly answers the question and output the answer.
