After the rain runs off your roof, where does it go? Q28 of The Big Here Quiz

I'm not sure how to verify my answer to this one. Assuming that the water doesn't get into the storm water sewer system, I would think that the water makes its way into the soil and then...

1) evaporate;
2) contribute to the soil's moisture
3) be used up by a plant;
4) collect in an aquifer somewhere below; or
5) make its way to the Detroit River

Its another one of those questions that is easy to answer with a principle ("the ground water cycle") but very hard to answer with something specific ("water in my neighbourhood collects underground and travels out via the stream").
