Suggestions for Remote Control Cleanup Exercise

Hi,

a few suggestions for improvment. First, the theory part is very short and lacks details/examples about nested classes accessing containing classes and vice versa. It makes it look like the solution is to create a nested "Telemetry" class. However, looking at the tests, "Telemetry" is used as a property. Simply creating a nested Telemetry class will lead to compiler error CS0572. For C# beginners this is extremely confusing.

Second, the wording of task 2 and its hint are confusing as well. How an Interface, instead of a simple access modifier, is the solution is neither handled in the theory part nor understandable to me using C# docs.
