Reworded: "The purchasing power of the consumer dollar has declined by 24.3% since 2001 (see chart below). The dollar actually strengthened for a brief 5-month period, from September 2008 to January 2009, but then resumed its decline, having fallen by 8.9% since January 2011. What happened to the price of gasoline during the five-month’s that the dollar strengthened? It declined dramatically, from $3.72 a gallon to $1.64 (see Part I). And what happened to the price of gasoline after January 2011? It shot past the $3.25 per gallon breaking point, where it remains today."

And in what proportion did the dollar get stronger/weaker? Not by that much. It would have been obvious in the prices of other things too.
