Your answer was: correct

Is it correct for sure?
According to my dictionary 'principle' is a noun and 'principal' could be a noun or an adjective - doesn't that mean in another words 'the main point'? So before 'point' should be an adjective, shouldn't it?

Hello,
Thanks for catching that mistake. You're right and that was a typing mistake. Principal is an adjective that means: the most important, consequential, or influential.
It's good to see you're using your dictionary - and that you are able to use the meanings properly.
Take care,
Linda
