The link isn’t loading for me. I also don’t really see how that matters if your cue is inherent to the situation in which you will use the information. To use a real life example, returning to a place you haven’t been in twenty years still conjures up hidden memories.
You can also make multiple cards/cues for the same information.
If we go with the example you mentioned as a card:
“You’re at a conference and you start talking to someone about [The Great Depression.] What are some key points to remember?”
there are a few issues
tl;dr by being complex but still a single card SRS isn’t actually going to strengthen the memory very well and you’ll be stuck with short intervals on a card that will take at least 10 seconds each rep. It will still work but it’ll take up much more time than it should. (The link explains it much better)
But it’s not a bad idea. If you answer the card and write out an answer, memorizing pieces of that answer in accordance with minimum information principle will leave better memory effect. While you might have 20 subcards, over time these will get much more accurate intervals from being atomic and actually take less times in rep than your massed question.
