Passage Summary: Twenty tax experts were given the exact same fake financial records to process, but they all came up with different results, and nineteen of them were wrong.

Reasoning: When twenty tax professionals were given the same set of records, none of their completed returns matched each other, and only one person actually calculated the taxes correctly.

Analysis: In a Must be True question, we treat the premises as absolute certainties. The data shows a staggering 95% failure rate among professionals and a 0% consensus rate. It seems that if you put twenty tax experts in a room, you’ll get twenty different opinions and a lot of incorrect math. Look for an inference that highlights the difficulty of the task or the unreliability of professional consensus in this specific field.
