Final answer:
Without context from a specific text, it's impossible to confirm whether Klev Schoening did not suffer from altitude sickness as Krakauer did; the answer requires information from Jon Krakauer's 'Into Thin Air' or related biographical sources.
Step-by-step explanation:
The question pertains to whether Klev Schoening suffered from altitude sickness during an event described in a narrative, as compared to the author Jon Krakauer. Without specific context from a text, we cannot determine the accuracy of this statement. However, considering this information generally relates to Jon Krakauer's experience, it could be derived from his book 'Into Thin Air,' which recounts his experience in a Mount Everest expedition.
If Klev Schoening is a character or a real person mentioned in the book and is noted not having had altitude sickness, then the statement could be true. Otherwise, without direct reference to Krakauer's narrative or biographical information about Klev Schoening's own experiences, we cannot assert the truth of the statement.
