[Used to strongly state the speaker’s firmly held opinions・Formal and rarely used (even in formal situations it is better to use に違いない)]
Just curious - with なadjs and nouns, when does one use である and how does it change the meaning? The page about this grammar point doesn’t seem to address that.
I came across this sentence in a review, and answered 「であるに相違ない」, and it was marked incorrect. The correct answer apparently is 「に相違ない」.
