Final answer:
Government regulations are the factor not responsible for the emergence of the Savannah Gateway Logistics cluster, as they do not inherently promote the development of such clusters unless they are trade-focused.
Step-by-step explanation:
The question asks which factor is not responsible for the emergence of the Savannah Gateway Logistics cluster. The options presented are a) Proximity to major markets b) Investment in transportation infrastructure c) Location in a foreign trade zone d) Government regulations. In considering these factors, proximity to major markets, investment in transportation infrastructure, and location in a foreign trade zone all contribute directly to the growth of the logistics cluster. These factors allow for easier and cost-effective transportation of goods and services, as well as incentives for trade and industry.However, government regulations, as a standalone factor, do not inherently promote the development of a logistics cluster; rather, they can often be a constraint unless specifically designed to encourage trade and commerce. Therefore, government regulations, unless specifically aimed at trade facilitation, are typically not a driving factor behind the emergence of a logistics hub.In conclusion, the main answer is that government regulations are the outlier and the factor least likely to be responsible for the emergence of the Savannah Gateway Logistics cluster.
