Passage Summary: A builder predicts that steel will soon dominate the housing market because it's getting cheaper and lasts longer, while the wood usually used for framing is getting pricier and worse in quality.

Conclusion: Within a decade, steel will replace wood as the primary material for new home frameworks in North America.

Reasoning: Wood is becoming more expensive and lower in quality, while steel is becoming cheaper, is more durable against rot and warping, and is better for the environment.

Analysis: The builder's argument is heavily focused on material costs and physical durability, but it ignores other practical factors that influence construction. To weaken this prediction, we should look for a hidden 'cost' or hurdle associated with steel that doesn't apply to wood. For instance, if steel requires specialized labor that is incredibly rare or expensive, or if steel frames make houses significantly harder to insulate, the builder's cost-saving premise falls apart. Look for an answer that introduces a significant disadvantage to using steel in residential settings.
