Final answer:
Mrs. Pennyweather's remark on a 'champion' is both general and lacking context. It is possible that she could be referring to literary prowess, but without further information, the specific accomplishment she is referring to cannot be determined.
Step-by-step explanation:
Mrs. Pennyweather is referring to a specific accomplishment of someone which the context does not provide. However, based on the information provided, it seems that she could be inquiring about the nature of an individual's remarkable performance or status. Since the context given does not contain any information about a sports event, artistic exhibition, or academic recognition, and given the close association of the name Pennyweather with literary accomplishments, one could speculate that she might be referring to literary prowess. It is important to note that without the specific context in which Mrs. Pennyweather's question is asked, we cannot ascertain the exact nature of the 'champion' she is referring to.
