Question

modernizing coal-burning power plants would most likely result in:
○ less acid rain and cleaner air
○ more acid rain and crop damage
○ more ash deposition
○ increased sulfur dioxide emissions

Explanation:

Modernizing coal - burning power plants typically involves implementing technologies to reduce emissions, especially sulfur dioxide (a major contributor to acid rain). So, modernization would lead to less sulfur dioxide emissions, which in turn causes less acid rain and cleaner air. The other options (more acid rain, more ash deposition, increased sulfur dioxide emissions) are contrary to the goal of modernization which aims at reducing pollution.

Answer:

The correct option is "Less acid rain and cleaner air" (the first option among the choices, with the circular radio button next to it).
