Which of the following passages offers the best possible explanation of why Simon walks off to the jungle alone?
"Here the littluns who had run after him caught up with him. They talked, cried out unintelligibly, lugged him toward the trees. Then, amid the roar of bees in the afternoon sunlight, Simon found for them the fruit they could not reach, pulled off the choicest from up in the foliage, passed them back down to the endless, outstretched hands."
"Simon turned away from them and went where the just perceptible path led him. Soon high jungle closed in. Tall trunks bore unexpected pale flowers all the way up to the dark canopy where life went on clamorously. The air here was dark too, and the creepers dropped their ropes like the rigging of foundered ships."
"He came at last to a place where more sunshine fell. Since they had not so far to go for light the creepers had woven a great mat that hung at the side of an open space in the jungle; for here a patch of rock came close to the surface and would not allow more than little plants and ferns to grow."
"Simon paused. He looked over his shoulder as Jack had done at a close ways behind him and glanced swiftly round to confirm that he was utterly alone. He squatted done, parted the leaves, and looked out into the clearing. Nothing moved but a pair of gaudy butterflies that danced round each other in the hot air."
"Now the sunlight had lifted clear of the open space and withdrawn from the sky. Darkness poured out, submerging the ways between the trees till they were dim and strange as the bottom of the sea. The candle-buds opened their wide white flowers glimmering under the light that pricked down from the first stars."
