Question

how did weather and climate influence historical trade patterns in the indian ocean?
a. monsoon winds made sea travel from somalia and arabia easier during certain times of year. traders took advantage of this to transport goods quickly along indian ocean trade routes.
b. the southeasterly flow of monsoon winds in july led indian traders to develop trade routes from india to indonesia and australia. as a result, maritime trade between india and australia thrived.
c. the exchange of southwesterly and northeasterly winds in the summer made indian ocean trade routes unsafe. this forced traders to seek alternate routes.
d. the indian ocean is frozen during several months of the year. as a result, indian ocean trade routes were unusable for a significant part of the year.

Explanation:

• Option A: Monsoon winds in the Indian Ocean change direction seasonally. Traders historically used these winds. For example, the north - east monsoon (November - March) and south - west monsoon (June - September) could be harnessed for travel. If the wind was in the direction of travel, it made sea travel easier and faster.
• Option B: The monsoon winds in July are south - westerly in the Indian Ocean (not south - easterly). So this option has an incorrect wind - direction fact.
• Option C: The exchange of south - westerly (summer) and north - easterly (winter) monsoon winds was actually used by traders (not making routes unsafe). They could plan round - trips. For example, go one way with the summer monsoon and return with the winter monsoon.
• Option D: The Indian Ocean is a tropical and subtropical ocean. It does not freeze for several months of the year.

Answer:

A. Monsoon winds made sea travel from Somalia and Arabia easier during certain times of year. Traders took advantage of this to transport goods quickly along Indian Ocean trade routes.
