Food Shortage

A world survey recently conducted by the U.S. posed the following question.'Could you please give us your opinion about the food shortage in the rest of the world?' 
It was a huge failure due to the following reasons.

In Africa,no one knows what 'food' is.
In western Europe, no one knows what 'shortage' is.
In Eastern Europe, no one knows what 'opinion 'is .
In South America, no one knows what 'please' means.
In America no one knows what 'rest of the world' means!
