I don't understand why Console.WriteLine(question) is necessary when the method already has a name, "ask"

I don't understand why Console.WriteLine(question) is necessary when the method already has a name "ask". We do we have to then use the name question in "Console.WriteLine"?

I just don't understand the purpose of string question when the method can already be called with Ask();

The Ask method outputs a question and then waits for an answer. So, Console.WriteLine is still used when you want to output only.

Also, Console.WriteLine(question) is the way it is used inside the definition of Ask, where calling itself would cause a recursive overflow (an infinite loop).

The Console.WriteLine() is a method created by C# SDK itself;

Or you can see Console.WriteLine() as the method existing in the system which you don't need to write but use/call directly.

While the Ask() is a method that we wrote for this lesson.
