Passage Summary: A long time ago, people lived all over the Levant. Then, the southern part emptied out while the northern part stayed full, even though the weather was the same. Scientists think the southerners left because they chopped down too many trees, ruining their economy.

Reasoning: The Levant was heavily populated; the south was abandoned 6,000 years ago while the north remained populated; scientists hypothesize the southern abandonment was caused by deforestation-induced economic collapse.

Analysis: Since we are looking for what 'Cannot be True,' we need to find a statement that directly contradicts the facts or the scientists' specific explanation. The hypothesis hinges on a difference between the two regions: the south collapsed because of deforestation. If we find an answer choice stating that the north was actually more deforested than the south, or that the south wasn't deforested at all, it would make the hypothesis impossible. Focus on the geographic distinction between the north and south regarding their trees and economies.
