Introduction
Duolingo's challenge of incorporating more real-world language scenarios into its lessons is a critical opportunity to enhance user engagement and learning outcomes. This improvement could significantly impact user retention, language proficiency, and overall product value. I'll approach this by analyzing user segments, identifying pain points, generating solutions, and proposing implementation strategies.

Clarifying Questions (5 mins)
Why it matters: Determines if we need to shift focus from gamification to practical application or find a new balance. Expected answer: Users spend 80% of their time on gamified lessons, 20% on practical exercises. Impact on approach: Would focus on integrating real-world scenarios into the core lesson structure rather than creating separate features.
Why it matters: Helps tailor real-world scenarios to users' specific needs and contexts. Expected answer: 40% travel, 30% work, 20% academic, 10% personal interest. Impact on approach: Would prioritize travel and work-related scenarios in our solution.
Why it matters: Determines the feasibility and scope of potential solutions. Expected answer: Duolingo uses NLP for speech recognition and adaptive learning algorithms. Impact on approach: Would explore solutions that leverage existing AI capabilities for personalized, context-aware language scenarios.
Why it matters: Helps identify if lack of real-world application is affecting advanced user retention. Expected answer: Strong retention for beginners, but 30% drop-off for intermediate and advanced users. Impact on approach: Would focus on creating advanced, real-world scenarios to improve retention of higher-level users.
