The UN conducted a survey and asked people from different countries and continents "Would you please give your honest opinion about the shortage the of food in the rest of the world?". As one would expect, the survey was a failure.
People in Africa did not know what "food" was. People in China did not know what "opinion" was. People in Europe did not know what "shortage" was. People in India/Pakistan/Australia did not know what "honest" meant. People in the Gulf countries did not know was "please" was. People in America did not know what "the rest of the world" meant.
I am reminded of this joke when I read this article.
