To determine the quickest way for Shred Head to fulfill the order for the guitar, we need to consider the modes of transportation and their connections to export routes.
Option A: Railroads to Hartsfield-Jackson International Airport could work, but air transport generally takes longer due to handling and security processes for goods, especially at airports.
Option B: Interstate Highway System to Hartsfield-Jackson International Airport could be relatively quick, as highways can facilitate efficient road transport.
Option C: Railroads to the Port of Savannah might not be the fastest option, considering typically rail transportation can be slower for shorter distances.
Option D: Interstate Highway System to the Port of Savannah would likely be the quickest option. The Port of Savannah is one of the busiest and fastest-growing ports in the U.S., known for its efficiency in handling cargo, and the Interstate Highway System allows for rapid road transport.
Considering all options, the BEST and most expedient choice for Shred Head to fulfill the order is:
D) The guitar will be transported by the Interstate Highway System to the Port of Savannah, where it will be shipped overseas.
