Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the system prompt to 'You are a formal assistant that responds in a professional tone.'
The system prompt (or preamble) sets the assistant's behavior consistently. Temperature affects randomness but not tone directly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set a high temperature (e.g., 0.9)
Why it's wrong here
High temperature increases randomness, not formality.
- ✓
Set the system prompt to 'You are a formal assistant that responds in a professional tone.'
Why this is correct
The system prompt defines the assistant's behavior and tone across the conversation.
- ✗
Set the frequency penalty to a high value
Why it's wrong here
Frequency penalty reduces repetition, not tone.
- ✗
Set max tokens to a low value
Why it's wrong here
Max tokens limits response length, not tone.
