A city section like this is read by matching each drawn form to a known urban element, then checking every option letter by letter rather than guessing whole options at once.
- $R$: a tall structure with a car parked on every level and a ramped face on one side. Stacking cars over multiple floors like this is the built form of a multi-level car parking structure, nothing else in an urban section looks like this.
- $Q$: the flat paved strip right at the base of that same building, at ground level, used by people on foot, so this is the footpath.
- $P$: a bridge like element projecting from an upper floor of the building, raised above the ground and enclosed, connecting across to something beyond. Elevated, enclosed pedestrian links of this kind are called skywalks.
- $S$: a level walking surface running along both edges of the water body shown in the middle of the section. A paved walk built along a waterfront like this is a promenade.
- $T$: an elevated guideway on the right carrying rail cars above street level on raised supports, the built form of a mass rapid transit corridor (an elevated metro line).
With $P$ = Skywalk, $Q$ = Footpath, $R$ = Multi-level car parking, $S$ = Promenade and $T$ = Mass Rapid Transit Corridor fixed, check the four options: (A) wrongly calls $R$ a footpath; (B) matches on $P$, $R$ and $S$; (C) wrongly swaps $R$ and $T$; (D) matches on $P$, $Q$ and $T$.
Let's summarize:
- A stacked structure with cars on every floor is always multi-level parking, never a transit line, and an elevated rail track with train cars is always a transit corridor, never parking.
- Ground level paved strips beside a building are footpaths; paved walks beside water are promenades; enclosed elevated links between buildings are skywalks.
The correct labelling is given by options (B) and (D).
