Final answer:
The better production in conveying Shakespeare's purpose can only be determined by evaluating each production's unique artistic concept and execution.
Step-by-step explanation:
In comparing two productions of Shakespeare's The Tempest, it is important to consider the artistic choices and interpretations made by each production. Each director will have a different reaction to the text, resulting in varying interpretations of the same story. Therefore, the better production in conveying Shakespeare's purpose can only be determined by evaluating each production's unique artistic concept and its execution.
