Final answer:
In 'Lord of the Flies' Chapter 7, the boys think they find a beast on the mountain, but it is actually a dead parachutist causing their fear.
Step-by-step explanation:
In Chapter 7 of Lord of the Flies, the boys do not actually find anything on the mountain. However, in the events leading up to Chapter 7, the boys believe they have encountered a beast on the mountain at night which is actually the dead body of a parachutist. The misconception of the beast continues to cause fear and panic among the boys and influences their actions and the group's dynamics.
The question seems to include irrelevant excerpts from different texts, which do not pertain to the novel Lord of the Flies by William Golding. Therefore, the actual finding on the mountain as stated in the book is the supposed beast, which turns out to be a parachutist.
