In 50 degree Fahrenheit water survival time and Gulf Coast navigation reference, which pairing is correct?

Explanation:
Cold-water survival time is driven by how fast the body loses heat, which depends on the water temperature and what gear you have. At 50°F, the window for surviving in the water is limited to a few hours. In the Gulf Coast navigation reference, the survival-time data for this temperature are found in Volume Four, which lists the 50°F entry as about 2.5 hours. That makes 2.5 hours paired with Volume Four the correct match. The other pairings correspond to different temperatures or different volumes, so they don’t fit the 50°F entry. To use the reference in practice, look up the water temperature and read the survival time from the corresponding entry in Volume Four.
