Create a 12-slide funny, meme-style academic presentation (not a role play) for 6 presenters, 8 minutes, on: "One Ola ride eases things for one rider, but lakhs of cars add traffic and pollution for everyone. Explain with externalities." Cover: why one ride is rational (private cost only), MPC vs MSC graph with Qm, Q* and deadweight loss, who pays the hidden cost (asthma patients, bus commuters, vendors), fixes (congestion pricing, parking fees, fuel tax, odd-even), and Delhi Metro as a positive externality. Use original cartoon memes on slides 2, 4, 6, 8, 10 and 11, with big bold captions and Delhi traffic humour, but keep the economics accurate and simple. Design: navy (#0F2A43) with saffron and teal accents, big fonts, minimal text, icons and illustrations, and a "Presenter 1-6" tag on each slide (2 slides per presenter). Title: "One Ola Ride, Lakhs of Cars" | Group 8 (57-65) | Business Economics-I, ending with a conclusion slide "One ride is rational. Lakhs are not." and "Thank you | Questions?". Exactly 12 slides, no invented statistics, no real people or copyrighted characters, and add short speaker notes in simple English.
