Passage Summary: People used to fight against new inventions even when their jobs were dangerous and awful, which proves that humans are more stuck in their ways than they are interested in being safe or comfortable.

Conclusion: Social inertia is a more significant driver of human behavior than the desire for safety or comfort.

Reasoning: History shows that people often resisted new technologies even when their current working conditions were miserable.

Analysis: The author assumes that 'social inertia' is the only possible reason for resisting these innovations. To weaken this, we need to provide an alternative motive for the resistance that actually aligns with a desire for safety or comfort. For example, if the new technology was known to be even more dangerous than the old miserable conditions, or if it threatened the workers' only source of income (their safety net), then the resistance wasn't about habit—it was about survival. Look for an answer that provides a rational, non-inertia reason for the resistance.
