The correct answer is option 3: shale gas production. Tracking technology refers to the use of advanced tools and techniques to monitor and track various aspects of shale gas production. Shale gas is a type of natural gas that is trapped within shale formations deep beneath the Earth`s surface. It is extracted using a method called fracking, which involves fracturing the shale rock with high-pressure fluid injections to release the gas.

Tracking technology is used in shale gas production to monitor and optimize the fracking process. It helps in tracking the movement of fluids, detecting any leaks or spills, and ensuring the overall safety and efficiency of the operations. This technology involves the use of sensors, remote monitoring systems, and data analytics to collect and analyze real-time data from the production site.

By closely tracking the various parameters and performance indicators, such as pressure, temperature, flow rate, and chemical composition, operators can make informed decisions and adjustments to enhance the productivity and minimize the environmental impacts of shale gas production.

So, although option 1 (food processing), option 2 (beverage industry), and option 4 (bauxite extraction) are not related to tracking technology in the context of the question, option 3 (shale gas production) is the correct answer.
