Final answer:
If the EL is on 1 coverage and shipment, it means there is a single layer of protection for the shipment, such as insurance coverage or packaging.
Step-by-step explanation:
If the EL (estimated lead) is on 1 coverage and shipment, it means that there is a single layer of protection and handling for the shipment. This could refer to insurance coverage or packaging of the shipment. For example, if a product is being shipped and it has an EL of 1 coverage, it indicates that there is basic protection for the shipment, but it may not cover all damages or losses.
