Practice 3: Reading Passage
The Museum Tour
Our class trip to the history museum was led by a friendly docent named Mr. Arthur. He wasn't a professional doctor of history, but he knew just as much as one. He showed us an ancient document—a letter written by a king 500 years ago.
Mr. Arthur explained that in the past, kings would indoctrinate their subjects to believe that the king was chosen by God. This doctrine kept the people docile and obedient. It was fascinating to see how teaching and beliefs were used to control a kingdom.
