Final answer:
When two power-driven vessels are meeting on the specified waters with a current, the vessel going upstream should sound the first passing signal.
Step-by-step explanation:
In situations where two power-driven vessels are meeting on the Great Lakes, Western Rivers, or other waters specified by the Secretary, and there is a current, the vessel going upstream is the one that should sound the first passing signal.
The reason for this is that the vessel going upstream is typically facing a stronger current and is at a greater disadvantage in terms of maneuverability. By sounding the first passing signal, it gives the vessel going downstream the opportunity to adjust its course and avoid a potential collision.
Therefore, the correct answer is option 1) The vessel going upstream.
