Thank you very much.
Yes, I think the sentence using an adjective "polite" is correct, too. The problem is I'm not so sure when an adverb is used in this pattern.

a. Tom is the more polite (one) of the two (boys).---correct.
b. Tom behaves the more politely (one) of the two (boys).---wrong.

As is obvious, the article before more makes sense when you think that one is hidden after polite, thus making a noun phrase; however, you can't do that in b because it is an adverbial phrase.

If b is correct grammatically, how do you explain the article before more politely?
Hello Kamo Shushoku,

Tom behaves more politely than John. (???)

I am not sure I understand your question.

Hopefully one of the trained grammar teachers here
will help you with this question.
