 Which is the best description of the relationship between the Doc and the captain?
The Ship's Cook, the man who accomplishes the daily miracle of turning offal into eatables, is in many ways the most vital man aboard a spacer. Cooking aboard a spacer is a job combining the more frustrating tensions of biochemistry, applied mycology, high-speed farming, dietetics and sewage engineering. 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. 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.
