Step 1: Understanding the Concept
This is a "Must Be True" / "Strongly Supported" question. The answer must be a direct, logical conclusion drawn from the given facts alone, with minimal outside assumption.
Step 2: Detailed Explanation
The given facts are:
1. British tin was found in a shipwreck near Israel from 1300 BC.
2. British tin was found in a shipwreck near France from 600 BC.
What can we conclude from these two data points?
The time span between the two finds is \(1300 - 600 = 700\) years.
In both cases, tin from a distant location (Britain) was being transported in the Mediterranean region.
Let's analyze the options:
(A) "Exclusively relied" is too strong. The finds don't prove other sources weren't used.
(C), (D), (E) These options make specific claims about traders, quality, or shifts in sourcing that cannot be proven by these two discoveries alone. We don't know who the traders were, why the tin was chosen, or what other sources were used.
(B) This statement is directly supported. The fact that British tin was part of a long-distance trade network at two points in time separated by 700 years is strong evidence that these networks were not a brief phenomenon but "persisted for centuries."
Step 3: Final Answer
Option (B) is the most reasonable and well-supported conclusion that can be drawn from the two specific pieces of evidence provided.
