Yes, you are correct! An environmental engineer might help an oil refinery reduce its toxic gas emissions.

To arrive at this answer, let's go through the options one by one:

A. Create mathematical models of what may happen to global temperatures in the future - This is typically the domain of climate scientists, who use climate models to predict future temperature changes. While environmental engineers may use these models as inputs for their work, it is not their primary responsibility.

B. Build and maintain a marine exhibit for an aquarium - This task falls more under the purview of marine biologists or exhibit designers, rather than environmental engineers.

C. Help an oil refinery reduce its toxic gas emissions - This is a common task for environmental engineers. They are responsible for designing and implementing strategies to minimize pollution and improve air quality, particularly in industrial settings like oil refineries.

D. Stock a lake with algae-eating fish - This activity is more closely associated with ecologists or fisheries biologists, who study the relationship between organisms and their environment. Environmental engineers focus on designing systems and technologies to prevent pollution, rather than specific biological management practices.

So, in summary, the correct option is C, which is "Help an oil refinery reduce its toxic gas emissions."
