only two

Answer 2

The benefits of using a rain garden include:

- **It prevents runoff**: Rain gardens are designed to capture and absorb rainwater, which helps reduce surface runoff.

- **It helps stop pollution**: By filtering rainwater as it passes through the soil and plants, rain gardens can help reduce pollutants entering waterways.

- **It controls nutrients in soil**: Rain gardens can aid in nutrient management by allowing nutrients to be absorbed by plants rather than being washed away.

The option "it provides endangered animals" is not a direct benefit related to rain gardens, though they can create habitat and support biodiversity indirectly.

So, the applicable benefits would be:
- It prevents runoff
- It helps stop pollution
- It controls nutrients in soil

Answer 3

If you need to select only two benefits of using a rain garden, the best options would be:

1. **It prevents runoff**: Rain gardens capture and absorb rainwater, leading to decreased surface runoff.

2. **It helps stop pollution**: Rain gardens filter rainwater, reducing the entry of pollutants into local waterways.

These two benefits highlight the primary roles of rain gardens in managing stormwater and protecting water quality.
