Choose one from a random set of passages, then discard it

Hi,

I'm a new user of Twine, struggling to make a first story-driven game for a Game Jam. Hope you can help me with the following:

We are trying to code a part of the game in which the player enters a set of passages, none of them with real choices, but with random text which we do not want to get repeated (think of it as different descriptions of a landscape each time the player advances). So if the player gets a "I see flowers" text, we do not want to get it displayed again, but another random text from a predefined set.

I have been toying around with history, previous and also look a bit into arrays, with no succesful results

We are using latest version of Harlowe, by the way.

Any help is appreciated
