 So, we've added our lists to the function, but the micro:bit still doesn't know _which_ number to pull from each.
 
 Thankfully, lists are ordered! We can use a concept known as **index** to target a specific number in each list. In most programming languages, the first item in a list has an index of 0, the second item has an index of 1, and so on.

 To create a visual indicator when the water is safe to drink on a sunny day, we need to write another decision point or conditional statement. This conditional will allow the micro:bit to evaluate whether the exposure threshold has been met. In sunny weather, this threshold is 6 hours.
