## Step 1<br />The problem is asking us to identify the situation where the state of visibility is a determining factor. The options provided are:<br />- If a VHF radio should be installed<br />- Whether a full moon will affect the tide<br />- Whether fishing will be good<br />- A safe operating speed<br /><br />## Step 2<br />We need to analyze each option and determine which one is most directly influenced by the state of visibility.<br /><br />## Step 3<br />The first option, "If a VHF radio should be installed", is not directly related to visibility. The installation of a VHF radio is more about communication and safety, not visibility.<br /><br />## Step 4<br />The second option, "Whether a full moon will affect the tide", is also not directly related to visibility. The full moon affects the tides due to gravitational forces, not visibility.<br /><br />## Step 5<br />The third option, "Whether fishing will be good", is not directly related to visibility. The success of fishing depends on various factors such as the type of fish, the time of day, and the season, not visibility.<br /><br />## Step 6<br />The fourth option, "A safe operating speed", is directly related to visibility. The state of visibility can greatly affect the speed at which it is safe to operate a vehicle or machinery. For example, in poor visibility conditions, it may be necessary to slow down to ensure safety.
