Final answer:
Charles and Hal's likely response to being told their sled is too heavy for the dogs to pull would be to dismiss the advice and blame the dogs rather than admitting any fault. Option B and OC are the correct answers.
Step-by-step explanation:
The response of Charles and Hal, when told that their sled is too heavy for the dogs to pull, is not specified within the presented excerpts. However, typically in Jack London's The Call of the Wild, where characters like Charles and Hal appear, the pair often exhibit stubbornness and disregard for advice.
They tend to blame the dogs for inefficiencies and refuse to acknowledge their own lack of experience. Based on similar character behaviors in literature involving sled dogs and sled weights, it's reasonable to infer that Charles and Hal are more likely to dismiss the advice and blame the animals rather than readjust the sled weight or accept that they were wrong.
In the story, Charles and Hal, the sled owners, mainly respond to the men's suggestion that their sled is too heavy for the dogs to pull by:
Refusing to admit their inexperience and blaming the dogs (Option B).
Trying to act as if they already knew that the sled was too heavy to pull (Option OD).
These responses show that Charles and Hal are not accepting responsibility for the situation and are unwilling to adjust or change their approach.
