Final answer:
The claim that Benjamin Franklin prayed for divine assistance to achieve moral perfection is false. Franklin was a deist who believed in self-improvement through personal effort and virtue, not through divine intervention.
Step-by-step explanation:
The statement about Benjamin Franklin praying to God for help to practice his plan for moral perfection is False. Considering Franklin's deist beliefs, he thought that a god set the universe in motion and did not intervene in human affairs.

His Autobiography details his efforts towards self-improvement and his belief in moral perfection through practical means and personal effort.
