Question

the state has declared that a former factory site is contaminated, although it doesnt know if the property poses a danger to the public. which expert should the state hire to learn about the risk, and what tasks should that person be able to complete? an environmental scientist, who can identify, prevent, and reduce pollution and hazards in and around the site an environmental restoration planner who can devise a plan to protect the environment surrounding the site an hydrologist, who can study the water located underground and in the atmosphere surrounding the site a geoscientist who can study and manage natural resources to protect the animals living near the site

Explanation:

The state needs to assess contamination - related risks. An environmental scientist can identify, prevent, and reduce pollution and hazards, which is most relevant for understanding the risk of a contaminated site. An environmental restoration planner focuses more on devising a restoration plan rather than assessing the risk initially. A hydrologist mainly studies water - related aspects and not the overall contamination risk comprehensively. The description of the fourth option is cut off but an environmental scientist is still the best fit among the visible options.

Answer:

an Environmental Scientist, who can identify, prevent, and reduce pollution and hazards in and around the site
