Problem: Montevideo:

Of much greater importance is the division of the city into 62 barrios: neighbourhoods or wards. Many of the city's barrios—such as Sayago, Ituzaingó and Pocitos—were previously geographically separate settlements, later absorbed by the growth of the city. Others grew up around certain industrial sites, including the salt-curing works of Villa del Cerro and the tanneries in Nuevo París. Each barrio has its own identity, geographic location and socio-cultural activities. A neighbourhood of great significance is Ciudad Vieja, that was surrounded by a protective wall until 1829. This area contains most important buildings of the colonial era and early decades of independence.

What had many of the city's barrios previously been?
---
A: geographically separate settlements

Problem: Korean War:

Meanwhile, on 10 October 1950, the 89th Tank Battalion was attached to the 1st Cavalry Division, increasing the armor available for the Northern Offensive.

Kim Il Sung and his government temporarily moved its capital to Sinuiju – although as UNC forces approached, the government again moved – this time to Kanggye.

Problem: ASCII:

C trigraphs were created to solve this problem for ANSI C, although their late introduction and inconsistent implementation in compilers limited their use. Many programmers kept their computers on US-ASCII, so plain-text in Swedish, German etc. (for example, in e-mail or Usenet) contained "{, }" and similar variants in the middle of words, something those programmers got used to. For example, a Swedish programmer mailing another programmer asking if they should go for lunch, could get "N{ jag har sm|rg}sar." as the answer, which should be "Nä jag har smörgåsar." meaning "No I've got sandwiches."

What was created to solve the problem for ANSI C?
---
A:
C trigraphs
