Question

why did many traders travel in caravans across the silk road?
to avoid paying market taxes completely
to hide from governments encouraging commerce
to ensure faster travel than single riders
to share protection against bandits and harsh terrain

Explanation:

• Option 1: Traders on the Silk Road couldn't avoid market taxes completely by traveling in caravans, so this is incorrect.
• Option 2: Governments along the Silk Road generally encouraged commerce, and hiding from them isn't a reason for caravan travel, so this is wrong.
• Option 3: Caravans (groups) don't travel faster than single riders; in fact, coordinating a group can be slower, so this is incorrect.
• Option 4: Traveling in caravans allowed traders to share protection against bandits (who targeted lone travelers) and deal with harsh terrain (like deserts, mountains) together, which is a valid reason.

Answer:

D. To share protection against bandits and harsh terrain
