Thesis Statement: Our local waterways are severely polluted, and actions must be taken to reduce the runoff that contributes to this pollution.

Which of the following is the best example of a topic sentence for an essay with this thesis?

1) Rain gardens are particularly useful near solid surfaces such as parking lots.

2) Rain gardens are located in 30 percent of the residential parkways in Allentown, Ill.

3) Rain gardens include plants and materials that help absorb water into the ground before it is washed into sewers.

4) Rain gardens are a natural way to reduce storm water runoff that pollutes local waterways

I would say the answer is number 4: Rain gardens are a natural way to reduce storm water runoff that pollutes local waterways

Explanation:

A topic sentence is meant to express the main idea of a paragraph, so I already scratch off number 1 and 2, since they do not have to do with polluted waterways and actions to stop it. This would mean it is between number 3 and 4. Although number 3 gives information about rain gardens, it does not mention that they are a way to stop or reduce pollution in local waterways. Therefore, the answer is number 4. I hope this helped!
