Memory hook (the whole ladder in one breath): "Caspian's the widest, Superior's the widest fresh, Baikal's the deepest, oldest, and biggest by volume, Tanganyika's the longest and second-deepest, Victoria's the biggest tropical, Titicaca's the highest navigable, the Dead Sea's the lowest and saltiest, and the Aral's the saddest." Eight lakes, eight distinct identities, zero overlap — read it back twice and the ladder stops feeling like a table.

Part 2: Indian Lakes

India's lakes are far more numerous and geographically scattered than the handful of "giant" lakes that dominate world geography — there is no single Indian lake that competes on the world stage for size or depth the way the Caspian or Baikal do — which is exactly why Indian lake questions are framed differently from world lake questions: rather than one dominant global ladder of superlatives, India's lakes are tested mostly through regional superlatives ("largest in India," "largest freshwater," "largest in the Northeast") and through a dense cluster of individual, unmistakable signature facts (Lonar's meteorite, Loktak's phumdis, Wular's shrinkage). Treat this part, therefore, less as one continuous ladder and more as a state-by-state gallery of distinct portraits, exactly as the mental-map technique in the opening section describes.
