Passage Summary: Even though free trade helps countries focus on what they do best and work faster, it's actually pretty dangerous because if a country only makes one or two things, they're in trouble if those things disappear or get ruined.

Conclusion: Specializing in specific products through free international trade carries significant risks.

Reasoning: Small countries often rely on a few exports like raw materials, which can be depleted, or foodstuffs, which can be destroyed by natural disasters.

Analysis: To find the conclusion, look for the statement that the rest of the passage is trying to prove. The first sentence presents a 'good news/bad news' structure: free trade increases productivity, *but* specialization is risky. The word 'after all' signals that the following sentences about raw materials and foodstuffs are premises supporting the idea that specialization is risky. Therefore, the claim that specialization carries risks is the main point. I would look for an answer choice that captures this central warning about the dangers of economic specialization.
