A city, not a single road
Last chapter the financial system was one pipe. That was a useful lie.
It is really a city: institutions (the buildings), markets (the squares where people meet), instruments (the contracts they sign) and services (the professions that help them).
Almost every question on this session asks you to name the parts of the city and say what each one does. So this chapter is mostly lists. The trick is to learn each list with its count, because a five-mark answer that names four of nine functions loses marks it did not need to.
