1. The correct answer is c. to enable the quick movement of troops in case of a nuclear attack.

To find this answer, you can start by doing some research on the history of the interstate highway system. The interstate highway system was established in 1956 under the Federal-Aid Highway Act, which was signed into law by President Dwight D. Eisenhower. One key reason for the construction of interstate highways was to ensure national security in case of a nuclear attack during the Cold War.

During the Cold War, there was a concern about the vulnerability of the transportation infrastructure, including road networks, to potential nuclear attacks. Therefore, the construction of interstate highways was seen as a way to ensure rapid movement of military troops and equipment in case of an emergency. This was specifically noted as a goal in the legislation that authorized the construction of the interstate highway system.

2. The correct answer is c. They have attracted businesses from around the world.

To find this answer, you can research the impact of ports on South Carolina's economy. Ports are crucial transportation hubs that facilitate trade and commerce. They serve as key gateways for importing and exporting goods and have a significant impact on the local and regional economy.

By having ports, South Carolina has been able to attract businesses from around the world. Ports provide access to global markets, making it easier for businesses to import raw materials and export finished products. This increases economic activity and creates job opportunities. Ports also attract logistics and shipping companies, which further contribute to the local economy.

3. The correct answer is b. Freight trains continue to carry products like sand, coal, and forest products.

To find this answer, you can research the role of railroads in South Carolina's economy today. Railroads have been a significant mode of transportation for goods in the United States for many years, and this applies to South Carolina as well.

In South Carolina, freight trains continue to play a crucial role in transporting various products such as sand, coal, and forest products. These trains provide an efficient and cost-effective means of moving large quantities of goods over long distances. The state's railway network allows for the transportation of goods to and from ports, manufacturing facilities, and other destinations.

While passenger trains may have a more limited role in South Carolina's transportation system, freight trains remain a vital component of the state's economy, facilitating trade and supporting industries like mining, manufacturing, and agriculture.
