I am looking for a single word that means that something is best supported by something else. In the relevant contexts, I would use the word to express the idea that there are better reasons for supporting a position rather than alternative positions. For instance, a context in which I might use such a word is the following:
According to s, x either requires or [is best supported by] y
Of course, the expression "x is best supported by y" is perfectly natural. However, I would like a single word in order to eliminate the extra verbiage, the superlative, and the preposition.
