Korean Political History II: Chapter 4, Exercise 2 — Possible Solution
======================================================================

QUALIFICATION
The source says elections occur only in single-candidate races where the
candidate is effectively selected beforehand by the party. Holding a vote does
not show a choice among candidates.

REWRITE
"North Korea holds elections, but according to the source they are
single-candidate races with candidates chosen beforehand by the party."

CAUTION
I did not find turnout figures or how candidates are selected.
