Are lists a structured data type or an abstract one?

Question

IT education

In the question for preparing the entrance exam, I came across: "Structured data types on the example of lists. Stack, queue, dec." And if everything is more or less clear with the last three friends, then there was confusion with the list. For by definition (Wikipedia):

...list is an abstract data type...

Clarify, to whom it is not difficult, I will be very grateful.

Answer 1

"Structured data types on the example of lists. Stack, queue, dec". And if everything is more or less clear with the last three friends, then there was confusion with the list.

Um, stack, queue and deque are varieties of lists.
I googled a little, and did not find such a thing as structured data types. (except for some bullshit in the context of Pascal)
But if we compare this term with wiki
then we can conclude that this is something like a clarification, showing that we are not talking about a random structure, but about a specific implementation.
