Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Test prompt with a diverse set of input documents
Why this is correct
Diverse testing reveals edge cases and overfitting.
- ✓
A/B test different prompt variants on a held-out set
Why this is correct
A/B testing provides empirical evidence of improvement.
- ✗
Always use the same input to ensure consistency
Why it's wrong here
Same input does not test generalization.
- ✗
Increase max tokens to the maximum allowed
Why it's wrong here
Max tokens does not improve summarization quality systematically.
