Step 1: Understand the passage.
The paragraph highlights that even when employees are bored, organizations often ignore their complaints as long as they continue to deliver good results. The issue is not lack of performance, but lack of recognition of the mental state.
Step 2: Evaluate the options.
- Option A: Fits perfectly. It directly reflects the idea that good performance masks the underlying boredom or dissatisfaction.
- Option B: Incorrect. The passage says bored employees may still be good performers, so being bad performers is not a necessary condition.
- Option C: Too extreme — the passage does not say boredom always needs “immediate attention.”
- Option D: Slightly misleading; boredom isn’t only created by mundane tasks, but rather exacerbated by repetition.
- Option E: Rephrases part of the passage but doesn’t capture the inference about organizational behavior.
Step 3: Best inference.
Thus, the best inference is Option A.
Final Answer:
