"Comparison between" versus "comparison for" [closed]
"Comparison between" is used when you are listing choices to be compared- as in, "We can make a comparison between Toyotas and Volkswagons."
"Comparison for" is used when articulating the intent of the comparison- as in, "We can compare these two answers for similarities."
So, "what's being compared" vs "what you're looking for during the comparison"
