Final answer:
The source of supreme executive power in a system of government is not from 'strange women lying in ponds distributing swords' or any aquatic ceremony, but rather from a mandate from the masses.
Step-by-step explanation:
The question is about the source of supreme executive power in a system of government. The answer is B. False. The quote from Montesquieu's 'The Spirit of the Laws' suggests that power in a government does not come from 'strange women lying in ponds distributing swords' or from some 'farcical aquatic ceremony', but rather from a mandate from the masses. The source of supreme executive power in a system of government is the consent and support of the people or the masses, not some mythical or ceremonial event.
