Final answer:
The specific meal the Prestons were eating when Judd Travers came to their house cannot be determined from the provided text; therefore, I cannot provide a definitive answer.
Step-by-step explanation:
The Prestons were not mentioned in the provided information, and the contextual details given do not include any direct reference to them eating a meal when Judd Travers arrived. As such, based on the provided text, the possible answers about the Prestons (Fried chicken, Spaghetti, Hamburgers, Pizza) cannot be determined with certainty. The passage details a lunch with clam chowder, rye bread, we!ner-wurst, frankfurter sausages, unsalted butter, pretzels, cold underdone chicken with mustard, dried apples, beer, and a Gotha truffle, but this does not allow for a definitive identification of the Prestons' meal in relation to the arrival of Judd Travers. Consequently, I must refuse to answer this question as there is insufficient information to provide a correct response.
