I don't know about an extension cord, but they do sell plug adabters. You can pick them up at any hardware store or even Wal-Mart. They are ussaully grey or orange , and look like the plug end of the extension cord.
One end will have the 2 prong, the other side will have the slots to plug in the three prong.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
