Impossible question.betcha cant figure it out. very tricky brain teaser?

I figured it out, but I don't want to give the answer away. It's very easy to come up with any number of scenarios. For instance, there is only one definitive answer to how many carrots were in the carrot bowl(3). When sally realized that all the carrots were gone, it doesn't specify what they were gone from(the garden, etc.?) The details do not specify where jimmy, carly, or jeromy got their carrots. To be facetious, you could say that jeromy picked his carrots out of thin air. So, to answer how this scenario is possible, you have to come up with variables that aren't mentioned. I could also say that sally returned to the group, saw no carrots being eaten, and umed the carrots intended to be eaten were all gone. There could also be 50 carrots remaining in the bowl, she only pulled out three of them(not the last three). OK, I'm done giving hints.
