Final answer:
The 2nd step in the election of a pope is the Papal Conclave, where cardinals vote in secrecy until a new pope is elected, which is then signalled by white smoke.
Step-by-step explanation:
The 2nd step in the process for the election of a pope is the Papal Conclave. After the announcement of vacancy of the Papal office, cardinals from around the world gather in the Vatican to participate in the Papal Conclave. During the conclave, the cardinals are secluded and vote for the new pope in secrecy. This process continues until a candidate receives a two-thirds majority vote. Once a new pope is elected, white smoke is released from the Sistine Chapel to signal to the public that a decision has been made.
