Final answer:
The value of product inventory as a percentage of Short Term Assets is less than 2%, based on the information that inventory changes typically account for less than 1% of GDP.
Step-by-step explanation:
The question is asking to determine the percentage of product inventory relative to Short Term (Current) Assets. As the information provided indicates that the change in inventories, which represents product inventory, is typically less than 1% of GDP, and since the alternatives suggest percentages that are significantly higher, we can infer the correct answer would most closely align with the provided data. Hence, we can conclude that the value of product inventory as a % of Short Term (Current) Assets is less than 2%.
