Official Explanation
The injuries and illness reported decreased more rapidly from_________than from 2003 to 2004.
The rate of injury and illness reported is represented by the slope of the line connecting the points. Consider each pair of points separately: 2004 to 2005 and 2006 to 2007 have essentially the same slope as 2003 to 2004; 2008 to 2009 decreases more steeply, but 2010 to 2011 is flat, neither increasing nor decreasing.
