When reading, list is a reference to the original list, and list[:] shallow-copies the list. When assigning, list (re)binds the name and list[:] slice-assigns, replacing what was previously in the list. Also, don't use list as a name since it shadows the built-in.
The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. (I didn't use it in the first example because you were overwriting that name in your code - which is a good example of why you don't want to do that!)
My question is in the significance of the -1 in return c.most_common()[-1]. Changing this value to any other breaks the code as the least common element is no longer returned. So, what does the -1 mean in this context?
The notation List means "a list of something (but I'm not saying what)". Since the code in test works for any kind of object in the list, this works as a formal method parameter.

By using a : colon in the list index, you are asking for a slice, which is always another list. In Python you can assign values to both an individual item in a list, and to a slice of the list.

You cannot put lists in sets since lists are mutable and could change (which could affect whether they are duplicate to another list in the set). I would suggest a different approach for a list of lists, e.g. as covered in this question about removing duplicates from a list of lists.
It is a list with six elements in it. To understand slicing better, consider that list as a set of six boxes placed together. Each box has an alphabet in it. Indexing is like dealing with the contents of box. You can check contents of any box. But you can't check the contents of multiple boxes at once. You can even replace the contents of the box.
(The list object must be iterable, implied by the for..in stanza.) The lesson here for new programmers is: You can’t get the number of items in a list without counting them at some point. The question becomes: when is a good time to count them?
