Passage Summary: Scientists found that lightning can create the building blocks of life, but only if there isn't much oxygen around. The problem is, they now think early Earth actually had plenty of oxygen.

Reasoning: Amino acids require a low-oxygen environment to form via lightning, yet scientists currently believe the early Earth's atmosphere was actually high in oxygen.

Analysis: The paradox here is a direct conflict between a laboratory requirement (low oxygen) and a historical theory (high oxygen). To resolve this, we need a bridge that allows lightning to produce amino acids even if the general atmosphere was oxygen-rich. Look for an answer that suggests a 'loophole,' such as localized environments where the oxygen levels were different from the global average. We aren't looking to prove the scientists wrong, but rather to find a way for both the experiment's results and the atmospheric theory to be true simultaneously.
