Can't be 5. Tube is capped at the end so must be 3 that fills

No, it's 4.the tap on 1 is lower, so the water will go to 3. The tap on 3 is the lowest toward 4. The others will not fill all the way because the water will flow to the lowest opening first

Because for number one to go to two the number two tank pipe has to be open but it is closed (which eliminates tanks 2,6,7). So the is only one pipe for tank one which leads to tank three. And all of the other pipes for tank 3 (except of course the one for tank one), the connection (pipe) for tank 4 is closed at the end and the connection for tank 5 is closed before the waster can even flow into the pipe.

So it is 3.
IT IS 3
