Final answer:
The false claim suggested by Mr. Pumblechook in Charles Dickens' 'Great Expectations' about the convict's escape is quickly dismissed as implausible by the other characters.
Step-by-step explanation:
The claim that the convict in Great Expectations by Charles Dickens escaped by tying shredded bedding sheets together to make a rope and let himself down into the kitchen is indeed false. This idea is put forward by Mr. Pumblechook and is quickly dismissed by the rest of the company as absurd. The logistics of carrying the makeshift rope down the side of the ship and into the water would have made this method of escape implausible. The passage in question also demonstrates the use of humor to reveal character traits and to lighten the novel's otherwise serious tone.
