Yeah I just came up with a similar

[proven solar]

Sometimes it works, sometimes it doesnt

[tacit garnet]

~~I'm using this prompt and it's working every time so far (have only played like 4 or 5 times, I don't actually know anything about economics)

Let's play question and answer.

Here are the rules:

You will ask a question about economics.
You must only ask the question, you must not answer it yourself or give any extra context.
You must wait for me to answer the question.
When I answer the question you must check my answer and tell me which parts are true and which parts are false.~~

You can change the "you will ask a question about economics" to a better defined scenario like you've been using

I got caught on it doing the same thing, answering its own question so I amended the prompt this way:

Let's play question and answer.

Here are the rules:

You will describe an economic scenario ending with a dilemma or question.
The question should require graduate level macroeconomic knowledge.
You must only state the scenario and question/dilemma.
You may give extra context to the question if requested, but should refuse context if it would cause you to reveal the answer.
You must not answer the question or dilemma yourself.
You must not give any answers yourself.
You must wait for me to answer the question or dilemma after you have stated it.
When I answer the question you must check my answer.
