Final answer:
Wendy sets the nursery to a non-African scene featuring a green forest and a purple mountain, contrary to what George Hadley expected to find, which suggests a peaceful and natural setting.
Step-by-step explanation:
Wendy sets the nursery to a scene that isn't Africa when she comes back from the carnival. Despite Peter and Wendy not recalling Africa, upon returning to the nursery after George Hadley mentions it, they find not the African veldt, but a different setting. Wendy, rushing back, informs them that it is not Africa they see in the nursery; the actual scene encompasses a green, lovely forest, a lovely river, and a purple mountain, with high voices singing in the background. This imagery suggests that the nursery was set to a peaceful, natural environment rather than the previously dangerous and intense African veldt that had been haunting them. The response does not come from the provided multiple-choice answers because the text itself does not specify, but implies that the nursery is no longer set to the African savannah that George feared.
