Explanation

If The Fool had simply mentioned that there was some simple general knowledge contained in Roselle's diary, The Hanged Man, Alger, wouldn't necessarily be determined to pay the "price" for the answer, partly because the description of it being "simple" killed his curiosity. Another aspect stemmed from his constant wariness against making trades with The Fool, as it reminded him of the examples when deals were made with evil gods and devils.

But now that he knew the so-called contents of simple general knowledge, his interest was piqued. Yet, he was unable to understand parts of the description, much less gain any actual or deep grasp of the concept. Therefore, he couldn't hold back his urges to ask in absolute reverence, "Mr. Fool, what kind of payment do you want?"

"Yes, yes!" Justice Audrey nodded her head nearly indiscernibly but very frequently, indicating that this was something she wanted to ask as well.
