+In this task, you need to implement a function to be able to
+divide ducks in the Duck Shop into two categories — those with some Kotlin-related stuff and those without it — and reorder them according to this condition.
 
 ### Task
 
 Implement the `divideDucksIntoKotlinAndNonKotlin` function from the `GameActionFunctionsService` class in
 the `org.jetbrains.kotlin.course.duck.shop.functions.action` package.
-This function should divide ducks into two groups - with any Kotlin attribute (the field `hasKotlinAttribute` is `true`) and without - and returns these two collections.
