Day 4: The Incredible H2O Journey

So, since I miss asking my students questions, I've got another problem for you to figure out. Can you guess the correct order of the pictures to show the path of water to the drinking cup?
Is it:

1. A B C D E F G H
2. H G F E D C B A
3. A B G H 3 C D 4
4. C B A H F G E D

A free glass of water to all of you who chose 4 for your answer. Here's the route. It's pumped into a tank on the ground (c). From there it's pumped up to the water tower (b). Next gravity brings it to the faucet (a). At this point, though, it's not ready to drink, so a container (h) is used to take water from the faucet to the top of the filter (f). Once the water is filtered, it ends up in G. That pail has a spigot on it, so the water can be emptied into the red cooler (e). That cooler usually has a bottle of ice in it, so the water gets cooled. From there it goes to my cup (d). I'm very grateful for a cool cup of water these days.
The 2nd photo shows a local village well. I estimate that it's about 25 feet down to the surface of the water. A rope with a bucket attached it dropped down into the well to get the water. I guess I'll stick with option #4.
