Final answer:
The increase in global business activity can be attributed to advancements in communication and transportation technologies, digital distribution of products and services, and international agreements that reduce trade barriers.
Step-by-step explanation:
The increase in global business activity has been significantly influenced by the enhancement in communication and transportation technologies. Globalization has largely been driven by various factors, including the reduction in transportation costs thanks to improvements in shipping and air cargo, as well as innovations in computing and telecommunications. These advancements have made it simpler and more cost-effective to manage economic connections over long distances, involving both production and sales processes.
The digitization of many valuable products and services has also contributed, allowing them to be distributed globally through telephones and computer networks at very low costs. Additionally, international agreements and the reduction in trade barriers like tariffs and quotas have further fostered global business interactions.
