I had a similar reaction--I know exactly what that dial does, my reaction was "it determines how hard the drill will screw something in until the front part starts going tick-tick-tick." On a physical level I know what it does and when to use it (all the way up for drill bits, really low for screws going into a soft material), but when I saw the questions I had no idea what the correct answer was. I've always found drills to be extremely intuitive--it's four really simple physical binary things: squeeze the trigger to make it go, flip the switch on top to make it go faster, turn the dial to make it it stop before it goes too hard, and punch the toggle to make it go the other way. I wish software was that easy.
