Most learners have been taught two things about Acol: that you should always show a suit if you can, and that if you open the bidding in a suit, you must have a REBID prepared. They have also been taught that a 1NT response to an opening one level bid shows 6-9 high card points,. All that considered, even those beginners who have not been taught anything more than that, should be able to stop in the correct contract on these very unexciting NS cards.
