instruction: Given that the current year is 2023, how old is Chevron?
context: Chevron traces its history back to the 1870s. The company grew quickly after the breakup of Standard Oil by acquiring companies and partnering with others, eventually becoming one of the Seven Sisters that dominated the global petroleum industry from the mid-1940s to the 1970s. In 1985, Socal merged with the Pittsburgh-based Gulf Oil and rebranded as Chevron; the newly merged company later merged with Texaco in 2001. Today, Chevron manufactures and sells fuels, lubricants, additives, and petrochemicals, primarily in Western North America, the U.S. Gulf Coast, Southeast Asia, South Korea and Australia. In 2018, the company produced an average of 791,000 barrels of net oil-equivalent per day in United States.
response: Because the current year is 2023 and Chevron traces its history back to the 1870s, Chevron is roughly between 143 and 153 years old.
