You're right. I just re-checked. 4.8 and 5 gave a blatantly wrong answer to a simple question, 4.6, Quen, GLM, Sol gave the right answer. They messed up somehow, not sure what they did.

What was the question?

(effort: high)

"can the pi 4 use the usb-c port as powered host port when the board is powered via gpio?"

Umm shouldn't that be "search the web and read the docs for pi4 to answer: ..."?

Weird then that they don't get it all correct.

Does a set of all sets contain itself?
