Final answer:
The correct completion of the sentence is 'gives in...capricious,' indicating that Chris always succumbs to his impulses and his unpredictability interferes with his productivity.
Step-by-step explanation:
The correct completion of the given sentence is 'gives in...capricious'. This sentence would thus read: 'Although Chris is a hard worker, he always gives in to his every impulse; he would be more productive if he wasn't so capricious.' The phrase 'gives in' fits because it refers to someone succumbing to something, in this case, impulses. The word 'capricious' indicates a tendency to make sudden and unpredictable changes, which aligns with someone who might be impulsive.
Chris, despite his hard work, seems to struggle with self-discipline, as suggested by the sentence. This reflects a broader narrative where Chris has given up on the traditional educational system and is pursuing his intellectual interests alongside blue-collar jobs. His internal battles, including the one where he tries to find peace from a dominating idea, and his weariness of the education system, emphasize the complexity of Chris's character as someone who is both industrious and yet struggles with impulsiveness. The reference to 'proper self-control' from LibreTexts™ highlights the importance of self-regulation.
