为解决这一问题，20世纪90年代早期曾引入混合选举制度，即同一选区内四分之三的席位仍由多数规则确定，而其余则按比例代表制产生。
In an attempt to solve the problem, a mixed electoral system was introduced in the early 1990's, with about three quarters of the seats assigned under plurality rule in single member districts and the rest allocated under proportional representation.
