Passage Summary: An economist claims we can never stop recessions because we can't predict them right now, and you can't stop what you can't see coming.

Conclusion: It is impossible to ever prevent global recessions.

Reasoning: Prevention is only possible if recessions are predictable, but current economic techniques consistently fail to predict them.

Analysis: The economist makes a significant leap from a current failure to a permanent impossibility. Just because economists using 'the best techniques at their disposal' cannot predict recessions today does not mean better techniques won't be developed later. Look for an answer that identifies this flaw of treating a present lack of ability as an inherent, unchangeable limitation.
