Generate Batch 1.
Batch 1 will process one item at a time.
This creates an operations array defining what batch 1 should do, including what it should do when it's finished. In this case, each operation is the same and by chance even has the same $nid to operate on, but we could have a mix of different types of operations in the operations array.
