HELP A GIRL ASAP PLEASE Which diagram best shows how an Enlightenment idea influenced the U. S.
Constitution?

It's definitely B, take my word on it.

here's what I found researching some websites.

"These thinkers valued reason, science, religious tolerance, and what they called “natural rights”—life, liberty, and property. Enlightenment philosophers John Locke, Charles Montesquieu, and Jean-Jacques Rousseau all developed theories of government in which some or even all the people would govern."

"The Enlightenment was influenced by reason because it was a time of optimism and possibility. People started to study human nature and society. What new views did philosophers have about government? These rulers inspired further rulers, and people began to believe that human reason could solve any problem."

"Montesquieu believed in the separation of power with checks and balances. Checks and balances are put in place to ensure that no one branch of government has too much power."

"Other enlightenment thinkers have influence on the US constitution. Volitaire's ideas are used. Volitaire believed in religious freedom which is practiced in the US today."

there's another link but for some reason says it has a swear word...

although the crusades failed to capture jerusalem, they had several major impacts on western europe. they increased the authority of the king: sometimes nobles died in battle without leaving an heir in which case the king got their land. kings passed taxes to pay for the crusades.
