Step-by-step explanation:
In 2013, Texas ranked first in the U.S. for several economic indicators. The economy of Texas has evolved from relying heavily on oil and natural gas to a more diverse economy. Houston, as the largest city in Texas and the fourth largest in the U.S., is central to this diversification with a strong presence in high-tech manufacturing, healthcare, business, and information technology. The space industry is a notable example of high-tech industry in Texas, as it homes NASA's Lyndon B. Johnson Space Center.
Texas state spending reflects this economic diversification, as the largest spending is allocated to healthcare and education, sectors known to contribute to economic growth and stability. Additionally, the presence of a high number of Fortune 500 company headquarters in Houston further exemplifies Texas's strong economic standing.
