Ask it to do the reverse. Connecting loosely related points to see the "hidden shape" behind them is an important feature of mind. Why do we see a cow above? That's just a bunch of lines and circle. The cow is a made up "meaning" behind these lines.

Edit: it's not unreasonable to give an LLM such test. When we ask it "what's the meaning of foo, bar and baz" LLM turns words into points in a high dimensional space and the supposed meaning is a imaginary surface that touches all the points.
