Best practice

Use "why that" to seek clarification on a specific statement or action. It directly prompts for the underlying reason or cause. For example, "The company chose to invest in renewable energy. Why that?"

Common error

Avoid using "why that" when a broader explanation is needed. It's best suited for direct follow-up questions about a specific point, not for initiating general inquiries. For example, instead of "Why that?" when asking about climate change, ask "What are the causes of climate change?"
