Make a table to help solve this problem. Cory, Srey, Molly, and Mao each visited a different city: Santa Clara, Seattle, Des Moines, and Pittsburgh. Cory and Molly visited cities with two words in their names. Mao and Cory visited cities whose names start with an S. Who visited Pittsburgh?

Cory and Molly visited the two cities with two-word names: Santa Clara and Des Moines. Cory’s city must start with S, so Cory visited Santa Clara, leaving Des Moines for Molly. Mao also visited a city starting with S, so Mao visited Seattle. That leaves Pittsburgh for Srey, making “Srey” the correct choice.
