Input: Article: The economic reforms of President Carlos Salinas de Gortari had a tremendous effect on the city, as a number of businesses, including banks and airlines, were privatized. He also signed the North American Free Trade Agreement (NAFTA). This led to decentralization and a shift in Mexico City's economic base, from manufacturing to services, as most factories moved away to either the State of Mexico, or more commonly to the northern border. By contrast, corporate office buildings set their base in the city.

Now answer this question: What did NAFTA do to the businesses in Mexico City?

Output: led to decentralization and a shift in Mexico City's economic base, from manufacturing to services

Input: Article: Geology existed as a cloud of isolated, disconnected ideas about rocks, minerals, and landforms long before it became a coherent science. Theophrastus' work on rocks, Peri lithon, remained authoritative for millennia: its interpretation of fossils was not overturned until after the Scientific Revolution. Chinese polymath Shen Kua (10311095) first formulated hypotheses for the process of land formation. Based on his observation of fossils in a geological stratum in a mountain hundreds of miles from the ocean, he deduced that the land was formed by erosion of the mountains and by deposition of silt.

Now answer this question: What science did Shen Kua observe?

Output: land formation
