In the novel Lord of the Flies, here are the explanations for your questions:

1. How does Piggy first notice a boy is missing, even though he doesn't know his name?

In order to determine how Piggy notices a missing boy, we need to refer to the text. Please provide a specific chapter or event where this incident occurs.

2. What feast does Piggy supply for Ralph and the fire builders?

In the novel, Piggy does not supply a feast for Ralph and the fire builders. However, Piggy does contribute to the group by providing a sense of rationality and practicality. He emphasizes the importance of maintaining the fire signal, which is essential for their rescue. Piggy's contributions are more focused on the group's survival and organization, rather than providing feasts.

3. How does Roger help in killing the sow?

Roger is a character who becomes progressively more brutal and sadistic as the story unfolds. In Chapter 8, the boys hunt and kill a female pig, referred to as a sow. Roger participates in the killing by sharpening a stake and positioning it in a way that impales the sow. His actions demonstrate the loss of civilization and the descent into savagery, as he takes pleasure in the brutal act of killing the sow. Roger's role in the killing reflects his gradual transformation into a remorseless and violent character.
