Read the passage from Animal Farm. Meanwhile the timber was being carted away at high speed. When it was all gone, another special meeting was held in the barn for the animals to inspect Frederick's bank-notes. Smiling beatifically, and wearing both his decorations, Napoleon reposed on a bed of straw on the platform, with the money at his side, neatly piled on a china dish from the farmhouse kitchen. The animals filed slowly past, and each gazed his fill. And Boxer put out his nose to sniff at the bank-notes, and the flimsy white things stirred and rustled in his breath. Three days later there was a terrible hullabaloo. Whymper, his face deadly pale, came racing up the path on his bicycle, flung it down in the yard and rushed straight into the farmhouse. The next moment a choking roar of rage sounded from Napoleon's apartments. The news of what had happened sped round the farm like wildfire. The banknotes were forgeries! Frederick had got the timber for nothing! Which statement best summarizes the theme of this passage?
