Given the task definition and input, reply with output. You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.

The main story of the novel is the narrative of the adventures of Adam More, a British sailor shipwrecked on a homeward voyage from Tasmania. After passing through a subterranean tunnel of volcanic origin, he finds himself in a "lost world" of prehistoric animals, plants and people sustained by volcanic heat despite the long Antarctic night.
A secondary plot of four yachtsmen who find the manuscript written by Adam More and sealed in a copper cylinder forms a frame for the central narrative. They comment on More's report, and one identifies the Kosekin language as a Semitic language, possibly derived from Hebrew.
In his strange volcanic world, More also finds a well-developed human society which in the tradition of topsy-turvy worlds of folklore and satire (compare Sir Thomas More's Utopia, Erewhon by Samuel Butler, or Charlotte Perkins Gilman's Herland) has reversed the values of 19th century Western society: wealth is scorned and poverty is revered, death and darkness are preferred to life and light. Rather than accumulating wealth, the natives seek to divest themselves of it as quickly as possible. Whatever they fail to give away to wealthy people is confiscated by the government, which imposes the burden of wealth upon its unfortunate subjects at the beginning of the next year of reverse taxation as a form of punishment.
Who finds the copper cylinder with the manuscript?
