A Coruña's growth occurred after the Spanish Civil War at the same speed as other major Galician cities, but it was the arrival of democracy in Spain after the death of Francisco Franco when A Coruña left all the other Galician cities behind.

Ex Input:
Which is deeper in the earth, rice farms or clay shales under Houston?, Context: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.

Ex Output:
clay shales
