I want to know the answer to the following question:
How was this achievement of advancing culture undertaken ?
All the background I'm provided with is that "While the Alexandrian empire did not survive its creator's death intact, the cultural implications of the spread of Hellenism across much of the Middle East and Asia were to prove long lived as Greek became the lingua franca, a position it retained even in Roman times.". Is that enough to answer the question?
Answer: no
