Answer:
a. Both were released from where they were by the power of God.
b. Both were used to free God's people from sin.
Step-by-step explanation:
a - when God told Jonah to go to Nineveh, Jonah refused and fled to the other side to run away as far as He could go. But the giant fish swallowed him, and he spent three days and nights in there.
after his days were full, God released Jonah from the fish's belly just like Jesus was lifted from the domain of death by the power of God.
b - just like Jonah was used by God to free the people in Nineveh,
Jesus was also used to save the whole world from sin.
