Excavations at the ancient Red Sea port of Berenike have revealed substantial quantities of Indian pepper, coconut shell fragments, and teak wood imported from the western coast of India during the first century CE. Some historians argue that this influx of eastern commodities was primarily driven by elite Roman consumer demand in Alexandria and Rome, which incentivized merchants to brave the seasonal monsoon navigation across the Arabian Sea. However, maritime logistical records from the period indicate that the volume of heavy, non-luxury timber—specifically teak used for shipbuilding and structural reinforcement in arid coastal settlements—equaled or exceeded the volume of high-value spices. Because teak is far denser and less profitable per unit of cargo space than spices or textiles, long-distance maritime transport of timber was economically viable only if merchant vessels could secure ballast-replacement revenue or guaranteed subsidies from local port administrators. Since no evidence of imperial subsidies has been recovered from administrative ostraca at Berenike, researchers conclude that the timber trade was sustained by merchant captains utilizing timber as functional cargo that doubled as necessary ship ballast on return voyages from India, rather than as a primary commercial cargo driven by Mediterranean consumer demand.
Which of the following is an unstated assumption on which the researchers' conclusion regarding the timber trade depends?
- Merchant vessels traveling from India to Red Sea ports required substantial dense weight in their holds to maintain navigational stability during transoceanic voyages.Answer
- BElite consumers in Alexandria and Rome had no interest in acquiring exotic Indian hardwoods for luxury construction or furniture making.
- CNon-luxury commodities such as teak wood yielded lower net profit margins for Indian exporters than did high-value spices like pepper.
- DAdministrative ostraca from other ancient Red Sea ports contain detailed records of imperial commercial subsidies.
- ERoman merchant captains rarely engaged in long-distance trade along monsoon routes without formal financial backing from Mediterranean merchant guilds.
