Question

what was one consequence of goods being exchanged repeatedly along the route?
prices decreased with each exchange
quality always improved after each trade
weights and measures stayed exactly the same
goods became more expensive over time

Explanation:

To determine the correct answer, we analyze each option:

• "Prices decreased with each exchange" is incorrect. Repeated exchange (e.g., along trade routes like the Silk Road) often involves markups at each stop, increasing prices over time.
• "Quality always improved after each trade" is incorrect. There's no guarantee quality improves; it could stay same or decline.
• "Weights and measures stayed exactly the same" is incorrect. Different regions have different systems, so they wouldn't stay exactly same.
• "Goods became more expensive over time" is correct. Each trader in the route adds their cost (profit, transportation, etc.), so the price of goods rises as they move through multiple exchanges.

Answer:

D. Goods became more expensive over time
