Final answer:
Transportation is a significant component of the costs incurred by most supply chains.
Step-by-step explanation:
The statement that transportation is not a significant component of the costs incurred by most supply chains is False. Shipping finished goods over congested street networks and jammed freeways can increase costs and reduce profits. Locations with access to uncrowded freeways, rail, or water transport can provide more cost-effective transport options. Therefore, transportation costs are indeed an important component of supply chain costs.
