I want to know the answer to the following question:
Houston is located in which Texas county?
All the background I'm provided with is that "With a census-estimated 2014 population of 2.239 million people, within a land area of 599.6 square miles (1,553 km2), it also is the largest city in the Southern United States, as well as the seat of Harris County.". Is that enough to answer the question?
