Question 67

The Correct Answer is D **Why option D ("Fresh water may be obtained from fish.") is correct:** Option D is the false statement. While fish contain water (like all living organisms), the extraction of drinkable fresh water directly from raw fish flesh, especially in a survival situation at sea, is impractical and inefficient. Furthermore, consuming raw fish carries risks of parasites and disease, and the water content extracted (often mingled with bodily fluids, fat, and proteins) would not constitute a reliable or safe source of potable drinking water compared to dedicated collection methods. Therefore, stating that fresh water "may be obtained from fish" as a reliable or sanctioned survival method is incorrect. **Why the other options are incorrect (i.e., why they are TRUE statements):** * **A) Fresh water may be collected from condensation inside the liferaft.** This is true. Solar stills and condensation collectors are standard (though often limited) methods used to desalinate water or collect evaporated fresh water within an enclosed liferaft environment. * **B) Lifeboat covers or canopies should be washed with rain before drinking water is collected.** This is true. The initial rainfall should be used to wash away salt residue, bird droppings, dust, and other contaminants that accumulate on the canopy before the water is deemed safe for collection and consumption. * **C) Seawater should never be consumed.** This is true. Seawater has a salinity much higher than human body fluids. Drinking seawater accelerates dehydration because the kidneys require more fresh water to excrete the excess salt than the amount of water ingested. Consuming seawater leads rapidly to serious dehydration, delirium, and death.
