Final answer:
The "hungry watchers" are individuals tasked with monitoring the hunger artist, ensuring he does not eat during his fast. They show varying levels of scrutiny, with some being lax while others are highly attentive, with the hunger artist preferring the loyal vigilant ones.
Step-by-step explanation:
The term "hungry watchers" in the context provided seems most closely associated with individuals who are supposed to monitor the hunger artist to ensure he does not eat. These watchers vary in their diligence; some are lax and allow the artist some respite, hoping he would sneak a bite, while others are more stringent, shining lights and staying attentive to prove that the artist remains true to his fast. The hunger artist finds the lax watchers disturbing as they seem to undermine the integrity of his art.
His preference lies with those who take their job seriously, to the point of using electric flashlights to keep an eye on him, despite his discomfort. This scenario illustrates the hunger artist's dedication to his art and the lengths he will go to prove his commitment, which even includes interacting with the watchers to stay awake all night.
