Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is impact on global trade. The 8,000-mile reduction and 14,000 annual ships demonstrate trade significance. The correct synthesis will use relevant details from the notes in a logical, purposeful way. Focus on what the question asks you to accomplish, then choose the answer that best achieves that goal using the provided information. Effective synthesis requires selecting and combining the most relevant information to achieve a specific purpose. Not all provided notes may be equally useful. Focus on what best accomplishes the stated goal while maintaining logical coherence.

Key Evidence:

• "emphasize its impact on global trade"

• "reduced by 8,000 miles"

• "14,000 ships pass through annually"
