Answer
No.Amazing Natural PhenomenaLocationOne Unique Feature
1The Valley of FlowersChamoli district, UttarakhandAround 600 species of exotic flowers (example)
2The Living Root BridgesMeghalayaBridges made of intertwined living roots, built without cement or stone; the longest is a whopping 175 feet
3The Lonar Crater LakeBuldhana district, MaharashtraThe only crater in India formed in basaltic rock by a meteorite impact; it holds a saline lake at its core
4Magnetic HillsLeh district, Ladakh — about 30 km from LehAn optical illusion in which parked vehicles appear to roll uphill at almost 20 km/h
5Glowing WatersKumbalangi village, 15 km from Kochi, KeralaBioluminescence — the backwaters glow at night because of a high concentration of micro-planktons
6The SundarbansWest BengalA mangrove forest spread over 1,400 km in the delta of the Ganga, the Brahmaputra and the Meghna, named after the sundari tree and home to the Bengal tiger
7The Invisible Chandipur BeachBalasore district, OdishaThe sea retreats 2–5 km during ebb tide and returns at high tide, so it seems to disappear and reappear daily
Choosing ‘one unique feature' is the real skill here. The right feature is the one that no other place on the list could claim. ‘Beautiful' is true of all seven and therefore useless; ‘the only crater in India formed in basaltic rock by a meteorite' belongs to Lonar alone. When you fill such a table, pick the most specific fact you can find, with its number attached.
Did you notice the spread? The seven wonders reach from Ladakh in the far north to Kerala in the far south, and from Meghalaya in the east to Maharashtra in the west — mountain, forest, desert, delta and coast. That range is part of the writer's argument.
