Passage Summary: Scientists think an asteroid killed the dinosaurs by blocking the sun with dust, but their own data shows the dust cleared out way too fast to actually cause a mass extinction.

Reasoning: N/A

Analysis: We are faced with a timeline discrepancy: the cause (debris) didn't last long enough to produce the effect (extinction) via the proposed mechanism (starvation/freezing). To resolve this paradox, we need a bridge that explains how a six-month event could still lead to a total biological collapse. Perhaps the six-month window was enough to trigger a secondary, longer-lasting disaster, or maybe the dinosaurs were more fragile than the scientists initially assumed. Look for an answer that explains how a short-term atmospheric change could have permanent consequences.
