question:  Which of these is the best description of the narrator?
context: Food, on the other hand, is a challenge shipmen face three times a day, so central to their thoughts that a history of sea-faring can be read from a commissary list. Should any groundsman dispute the importance of belly-furniture in history—whether it be exterminating whales, or introducing syphilis to the Fiji Islanders, or settling the Australian littoral with cross-coves from Middlesex and Hampshire—he is referred to the hundred-and-first chapter of Moby Dick , a book spooled in the amusement tanks of all but the smallest spacers. A catalogue of sides of beef and heads of Leyden cheese and ankers of good Geneva would prove heavy reading for a man condemned to snack on the Chlorella-spawn of cis-Martian space. And for a third footnote to the ancient observation, "God sends food, and the Devil sends cooks," Marsmen will recall what happened aboard my ship the Charles Partlow Sale . It's the Cook's responsibility to see that each man aboard gets each day no less than five pounds of water, two pounds of oxygen, and one-and-a-half pounds of dry food. This isn't just a paragraph from the Spacer Union Contract. By allowing a colony of Chlorella algae to work over our used air, water and other effluvia, though, three tons of metabolites would see us through from Brady Station to Piano West and back. Each molecule of oxygen would be conversant with the alveoli of every man aboard by the end of our trip. My duties are to serve as wailing-wall, morale officer, guardian of the medicinal whiskey and frustrator of mutual murder. Generally the man aboard who'd serve as the most popular murder-victim is the Cook. This trip, the-man-you-love-to-hate was our Captain. It was Winkelmann who saw humorous possibilities in the entry, "Bailey, Robert," on Ship's Articles.
