 To make it more clear where givens in the current scope are coming from, a special form of the `import` statement is used to import `given` instances.
 The basic form is shown in this example:
 
-{% tabs given-imports-basic-form %}
-
-{% tab 'Scala 3 Only' %}
-
 ```scala
 object A:
   class TC
@@ -28,28 +25,15 @@ object B:
   import A.given   // import the given instance
 ```
 
-{% endtab %}
-
-{% endtabs %}
-
 In this code the `import A.*` clause of object `B` imports all members of `A` *except* the `given` instance, `tc`.
 Conversely, the second import, `import A.given`, imports *only* that `given` instance.
 The two `import` clauses can also be merged into one:
 
-{% tabs given-imports-merged %}
-
-{% tab 'Scala 3 Only' %}
-
 ```scala
 object B:
   import A.{given, *}
 ```
 
-{% endtab %}

 ## Discussion
 
 The wildcard selector `*` brings all definitions other than givens or extensions into scope, whereas a `given` selector brings all *givens*---including those resulting from extensions---into scope.
