The language here should be 'invoking', which means it doesn't really fit into `ExecuteATaskFromATask.cs`.

Here's an idea:

```C#
public static class ExplicitTaskCalls // rename the class + file
{
    [Scenario]
    public static void ExplicitTaskExecution // rename the pre-existing scenario
    ....

    [Scenario]
    public static void ExplicitTaskInvocation // the new scenario
    ...
}
```
