Digital ACT Reading Practice Question #1225

The following passage is adapted from an essay on maritime archaeology: "The excavation of the Uluburun shipwreck, dating to the late fourteenth century BCE, revolutionized Mediterranean Bronze Age historiography. Previously, academic consensus viewed Mycenaean and Levantine polities as insular, engaged primarily in localized coastal barter. Yet recovered from the vessel's hold were over ten tons of Cypriot copper ingots, tin ingots likely originating from Central Asian highlands, Baltic amber beads, and Egyptian royal scarabs. This catalog of cargo proved that Bronze Age trade was not merely an incidental exchange of prestige curiosities, but a deeply integrated, transcontinental economic nexus vulnerable to systemic supply disruptions." According to the passage, how did the Uluburun shipwreck discovery challenge previous historical consensus?
