		+	I'm surprised that NPN transistor was used for the Trolley Problem instead of PNP. It would make a lot more sense because the PNP symbol has an arrow pointing towards the center, which corresponds nicely with the trolley heading towards a fork.

 The title text is probably a reference to the classic novella "The Scarlet Letter" by Nathaniel Hawthorne (a common classroom reading in the US). In this novella, a young Puritan woman "sins" by having a child out of wedlock. She is punished by having to wear the letter A (for adultery).

		+	::From my perspective, you also need to consider flyovers (bridges rising above grade, usually more minor or singular carriageways compared to the at-grade main road with or without median-separated carriageways). If the main route rises over the minor (which remains at-grade, more or less) with clear over-ground construction, it's just a road-bridge. An underpass need not be subterrainean, and often can be an at-grade "original" route (typically pedestrian) beneath the embankmented new major road (or other route, e.g. rail) that was engineered across it, in the same subtle manner as a culvert. Or even what you'd now term the stretch of road "bridged" (or tunnelled) beneath the building of a cross-highway shopping centre, like some towns do in order to sustain an inner ringroad and a large footprint shopping centre.
		+	::In general, if the 'over' road doesn't really notice the 'under' (it's still mostly the same grass verging, maybe briefly slightly higher crash-barriers on top of whatever embankment-guarding barriers already exist but no clear 'bridge' details) then I'd just name the underpass as such, as everything on that is definitely going to know that it is diving under the upper route
		+	::It can be complicated. The {{w\|File:No pedestrians (geograph 5985118).jpg\|extended runway seen here}} is possibly at-grade overpass, w.r.t the whole airport "level" (equivalent to a by-pass embankment?), while the road looks sunken (as can be seen by how much the pedestrian side-portal need not be). It could be a runway on an overpass, though I'd say the road is an underpass (with a possible argument that it was always a cut'n'cover tunnel, or passing under ''really'' long bridge).

	:Behaviorally the description makes sense, capacitors behave the same way regarding voltage vs. current as inductors behave regarding current vs. voltage and vice versa. Capacitors can "instantaneously" allow a spike in the current flowing through the circuit path that they are placed in, while the voltage across a capacitor can't change instantaneously and requires time to change incrementally (with a corresponding decline over time in the current flowing). Inductors "instantaneously" allow the voltage across their terminals to spike, but the current flowing through it can't change instantaneously and requires time to change incrementally (with a corresponding decline in the voltage across the inductor). Capacitors can act as a sort of "shock absorber" (no pun intended) or low-pass frequency filter for voltages, as inductors can for current. So they are very much considered complementary and the "essentially the opposite of capacitors" comment does pretty much make sense to EEs. But yes, it's not a particularly illuminating description without that background, and the description isn't really valid regarding their physical makeup or what makes them tick, just their role in a circuit.

	The "overpass" is troubling me, as a map fan. Dependant upon the conventions of any given map illustrator this could easily be more an ''underpass'' (main road being the \|\| track, lesser track being the — that sneaks beneath it) or a 'green bridge' (road is the — and the bridge 'symbol' is the \|\| with no actual route using the space between its edges) or a minor road intersection of an uncrossable dual carriageway (each \|\| is a directional way, separated by central reservation, and a historic road/lane is given T-junction access to/from the adjacent direction of travel, but no local flyover to access the opposite continuation/direction, probably have to use other flyovers/turning points above and below this snapshot). Or it's just a regular major/minor crossroads (track-level horizontal/E-W, more main road vertically/N-S) and is entirely at-grade so not involving a bridge at all. But all very much will rely upon the publisher's/renderer's choice of map-symbolism.
