The current sentence is: "While this can be interpreted as a response to World War II, it can also be seen as an analysis - a depiction of how fragile society actually is, and how easily it can be disrupted." However, I want to change the word "easily" in the last part of it to a word that means both "quick" and "easy." Of course, now that I need a word that covers both of those meanings, I can't think of one!
After consulting several reverse dictionaries and thesaurus.com, here is what I found (all definitions off Merriam-Webster):
a: without hesitating. b: without much difficulty
showing or requiring little or no difficulty
a: easily accomplished or attained. b: used or comprehended with ease.
marked by ready ability to move with quick easy grace
