Passage Summary: The government is really good at finding and taking fake money out of the system. However, the people making the fake money are still finding it easy to use those bills at businesses.

Reasoning: The government is successfully catching and removing fake money from circulation, but criminals are still having no trouble spending that fake money at stores and banks.

Analysis: We need to reconcile the government's success in removing bills with the counterfeiters' success in passing them. The removal might happen after the bills have already been successfully spent, or perhaps the volume of new fakes being printed is so high that the government's removals do not put a dent in the criminals' initial success. Look for an answer that explains how both successful removal and easy passing can happen simultaneously. The key is often the timing or the sheer volume of the activity.
