exports (trillions of us dollars)
2010 2011 2012
which might be a better title for this graph?
total exports for the united states and china
trade between china and the united states
unemployment in the united states and china
the history of international trade

Explanation:

The graph shows total merchandise exports of the United States and China from 2010 - 2012. The best - fitting title should focus on these exports. The first option is appropriate as it specifically mentions total exports for the two countries. The second option is too broad as it includes all trade, not just exports. The third option is about unemployment which is not related to the graph. The fourth option is too general about the history of international trade.

Answer:

Total Exports for the United States and China
