The text doesn't say she was born in Poland. It says she was Polish. It also doesn't say her nationality at death was French, it says she was naturalized-French at some point. It also states she conducted _pioneering_ research on radioactivity, which is not captured by the example output.
The example also shows an inferrence that her job is "researcher." This is a questionable inferrence. Imagine this conversation between two humans: "He's a hard-surface texturing artist, but he coded sometimes when he needed to." "Oh so his jobs are art and coding?" "No his job is art, but he can code."
As humans, we are thinking about role assignments and expectations vs people committing acts. What ultimately defines a "job"?
The point I'm trying to make is that "She was a researcher." and "She did research." should not result in the same output.
There's obviously a lot of inferrence required to discern any structure from the text (like assuming "she" refers to Marie Curie), but I believe these inferrences should be recognisable -- captured in the output in a way they can be queried and reasoned about.
