Question: Give a brief explanation of how to handle a development set that is too small to divide further, and name the ways it may still be used.

Sample answer: If the development set is too small to split, keep all of it together and use it as the manual-review development set. That set can then support detailed error inspection, comparison among candidate models, and hyperparameter adjustment.

Key points:

• The development set is too small to divide.
• Keep the full set together.
• Use it for detailed error inspection.
• Use it for model comparison.
• Use it for hyperparameter adjustment.

Rubric: A strong response says the set should stay intact, identifies it as the manual-review development set, and names all three uses. Partial credit should be given if the answer correctly recommends keeping the set whole and lists one or two of the uses.
