Try a sample question

You are building a sentiment classifier. Your zero-shot prompt returns inconsistent labels like 'positive', 'POSITIVE', and 'Positive'. What is the most effective single change to fix this?

A.Switch to a larger model which follows instructions more reliably
B.Ask the model to 'always use lowercase' at the end of the prompt
C.Increase the temperature so the model is more decisive
D.Add 2-3 labeled examples to the prompt showing the exact label format you expect
