Step-by-step explanation:
In the story, 'The Veldt' by Ray Bradbury, Wendy provokes Peter to anger when talking about Captain Hook by challenging his belief that the nursery is showing them things that aren't real. When George Hadley, their father, suggests that they have been spending too much time in Africa, Wendy insists that the nursery isn't showing them Africa. This contradicts Peter's assertion that the nursery can show them anything, including Captain Hook. Wendy's challenge to Peter's belief causes him to become angry.
