I don't understand the point or meaning of the text after the period? This is a confusing question.

I'm not making sense of this question and have no clue what the text after the period means.

I assume you are talking about the examples showing things like "text.something()".

The period is known as a "membership operator" and in this case it goes between a variable and a method name that is associated with the kind of thing the variable holds. A method is very much like a function.

The quiz references methods used on strings and lists, like "copy", "join", and "split". If you're not familiar with what these methods do and the syntax for using them, you may want to review the video(s). The quiz page has a handy "Review Video" button to get to them.
