Final answer:
The right answer to 'Who understands his wife more than Mr. Penn?' cannot be determined based on the provided text. Without further information on Mr. Rosicky or his relationship with his wife, we cannot make a reliable comparison.
Step-by-step explanation:
Based on the excerpt provided, it's evident that Mrs. Penn has strong personal convictions and acts independently. The fact that Mr. Hersey, the minister, finds her difficult to understand highlights that she is a complex character not easily dictated by others, including her own husband. Without more context about Mr. Rosicky's understanding of his wife, the question 'Who understands his wife more than Mr. Penn?' cannot be accurately answered.
Since the text only provides details on Mr. Penn and the minister's perspectives and no comparative information about Mr. Rosicky or his relationship with his own wife, the most appropriate answer is 'Cannot be determined'.
