c. Warn of an oncoming vessel on the port side
d. Are only for decorative purposes

Answer 1

On the Great Lakes, two short blasts signal a vessel's intention to turn to the left or maneuver to its port side as per maritime navigation rules.

Step-by-step explanation:

In the context of maritime navigation on the Great Lakes, two short blasts of a ship's whistle or horn signify that the vessel intends to turn to the left or maneuver to its port side. It is a signal used to communicate the captain's intentions to other nearby vessels to prevent collisions and ensure safe passage. The code for sound signals such as these would be found in the navigation rules known colloquially as 'The Rules of the Road'. This maritime regulation ensures that there is a standard set of signals that are widely understood and adhered to by seafarers.
