Explanation
Choice B is the best answer. In essence, the text asks what the conclusion would be if the fragments found at Zeugma were older than the foundation of the city. That would mean that they were not made by the city’s inhabitants, but were made elsewhere and then found their way into the city by some other means.
Choice A: The text does not mention any fragments from the 3rd century BCE. Therefore, this answer choice is not relevant to the reasoning in the text.
Choice C: Even if this answer choice were true, it would still not explain how the fragments could be older than the city in which they were found.
Choice D: The physical conditions of the fragments are not relevant to the reasoning in the text.

Examine the logical connections among the elements discussed in the text: the fragments are older than the city in which they are found, which means that they could not have been made by the city’s inhabitants.
