Final answer:
The heterogeneity of products on a given truckload is expected to become narrower in the future due to the widespread adoption of intermodal containers and advancements in technology.
Step-by-step explanation:
As a result of globalization and new information and communications technology, the heterogeneity of products on a given truckload is expected to become narrower in the future.
The widespread adoption of intermodal containers, which revolutionized the shipping industry, allows competing companies to mix and match cargo on a single transport carrier. This standardization and efficiency in shipping have led to a decrease in the variety of goods on a truckload. Additionally, with globalization and advancements in technology, companies can now quickly and easily transport standardized products across borders, further reducing the heterogeneity of products on a given truckload.
