The Enlightenment focused on the idea that logic, rationale, and reasoning were the most important ways to find a solution to everything in life, as well as the importance of each human and his capacity to make decisions.
I assume the underscores show which parts of the text were underlined:
"all men are created equal"
"unalienable rights"
"life, liberty, and the pursuit of happiness"
"governments are instituted among men"
"consent of the governed"
"it is the right of the people to alter or to abolish it"
The D of I best shows Enlightenment thinking in the ideas that 1)everyone deserves the right to life, liberty, and pursuit of happiness, and 2)people establish a government to protect themselves, and have the right to change it if the government starts to opress them. I'm not sure how many of the answer choices you have to choose — if there's any more information on the question's requirements, let me know and I'll do my best to add on. Hope this helps at least a bit
