Answer 1

When moving cars to couple to other cars in bad weather or when the rails are slippery, the train operator must make at least one stop to ensure a safe and secure coupling.

Step-by-step explanation:

When moving cars to couple to other cars in bad weather or when the rails are slippery, the train operator must stop at least once to ensure a safe and secure coupling.

This is because bad weather conditions or slippery rails can affect the ability of the cars to couple properly, and stopping allows for better control and accuracy when connecting the cars.
