Reasoning: No reasoning (Fact Set).

Analysis: We are looking for the one option that does *not* help explain the massive increase in trade.

The correct answer will likely be a piece of information that is either irrelevant to trade volume or describes a factor that would have hindered growth rather than helped it.
