-Your friend is a Locomotive Engineer who drives cargo trains between cities.
-Although your friend is great handling the trains, they aren't amazing handling the logistics computers and would like your programming help organizing the train and correcting mistakes in the data.
+Your friend Linus is a train driver who drives cargo trains between cities. Although they are amazing at handling trains, they are not amazing at handling logistics or computers. They would like to enlist your programming help organizing train details and correcting mistakes in route data.

 To practice, use the rest or spread operator to solve each of the tasks below.

 ## 1. Create a list of all wagons
 
-Your friend has been keeping track of each wagon identifier, but they're never sure how many wagons they are going to have to process at any given time. It would be much easier for the rest of the logistics program to have the data to be returned as an array.
+Your friend has been keeping track of each wagon identifier (ID), but they are never sure how many wagons the system is going to have to process at any given time. It would be much easier for the rest of the logistics program to have this data packaged into a unified `array`.

 ## 2. Move the first two elements to the end of the array
 
-At this point, you are starting to get a feel for your friend's data and how it's used in the logistics program.
-The train ID system works by assigning the locomotive an ID of `1` and then assigning the remainder of the wagons a randomly chosen ID greater than `1`.
+At this point, you are starting to get a feel for the data and how it's used in the logistics program. The ID system always assigns the locomotive an ID of **1**, with the remainder of the wagons in the train assigned a randomly chosen ID greater than **1**.
 
-But then your friend had to connect two new wagons to the train and forgot to update the system!
-Now the first two wagons in the `array` have to be moved to the back of the train, or everything will be out of order.
-Your friend would be really grateful to you for fixing their mistake.
