I once had a question on an exam for high voltage power “why do high voltage transmission lines have 3 wires”. The answer I put seemed obvious, that each wire is for one of the 3 phases of electricity. This is the standard config for HV lines in the US. The answer was wrong, because the professor was talking about INSIDE the cable and wanted an answer relating to how the electromagnetic field rotates around the wire so they bunch wires inside each line to improve efficiency. Professors, especially elite ones, have seemingly perfected the art of being vague. As a student you have zero recourse against them for their terrible communication skills, your only hope is to dodge the whacky ones by befriending upperclassmen/being in a frat.
