Q: Question: What was the name of the convicted rapist/murderer's mother that Don Dunstan advocated for? Passage 1:Since the late 1980s, the team has continuously been visible as a solidly competitive side, with a prominent performance in the 1990 FIFA World Cup in Italy, making it to the knockout stage in their debut after finishing second in their group during the first phase, below Brazil. They also managed to qualify for the 2002 and 2006 FIFA World Cups. In 2014, Costa Rica made their best performance in history by finishing first in their group that consisted of three former World Cup champions: Uruguay, Italy, and England. During the Round of 16 they defeated Greece 5–3 via a penalty shootout after a 1–1 draw. Moreover, during the match against a much better team, Navas saved more than 15 shots due to the Costa Rican very weak defense. The match was characterized as "Navas vs Greece". They reached the quarterfinals for the very first time as the Ticos were defeated by the Netherlands also in a penalty shootout (3–4) after a scoreless draw on 5 July. Their 2018 World Cup campaign ended in a 4th place group stage exit with their only point coming from a 2-2 draw vs Switzerland.
 Passage 2:Boynes was the 13th selection in the 1978 NBA Draft by the New Jersey Nets. The Nets had acquired the pick from the New York Knicks, along with Phil Jackson on June 8, 1978, in exchange for the Houston Rockets' 1978 first-round draft choice (Micheal Ray Richardson) and the Nets' 1979 first-round draft choice (Vinnie Johnson). In two seasons from 1978 to 1980, he played 133 games for the Nets, averaging 9.0 points, 2.2 rebounds and 1.3 assists per game. In 1980, Boynes was made available in the NBA expansion draft in which he was selected by the Dallas Mavericks. He was part of the starting lineup for the Mavs' first NBA game in 1980, in which he top-scored with 21 points in a 103–92 victory over the San Antonio Spurs.
 Passage 3:In the late 1950s, Dunstan became well known for his campaign against the death penalty being imposed on Max Stuart, who was convicted of rape and murder of a small girl. He harried Premier Thomas Playford IV aggressively over the matter, creating an uproar over what he saw as an unfair process. Playford eventually relented, and appeared shaken thereafter; the event was seen as a turning point in the Liberal and Country League's decline, and Labor gained momentum. During Labor's time in opposition, Dunstan was prominent in securing some reforms in Aboriginal rights, and was at the forefront of Labor abandoning the White Australia Policy. Labor conducted an extensive campaign in marginal LCL seats at the 1965 election, resulting in 21 of 39 seats, with Frank Walsh and the Labor Party taking power and Dunstan becoming Attorney-General. The LCL opposition changed leaders and installed the young Steele Hall, worrying Labor as the elderly Walsh appeared bumbling in contrast. This resulted in Labor replacing Walsh with Dunstan. Despite maintaining a much larger vote over the LCL, Labor lost two seats at the 1968 election, with the LCL forming government with support of an independent. Dunstan responded by increasing his attacks on the Playmander and was able to convincingly sustain Playmander attacks with the effect of convincing the LCL into watering down the malapportionment. Again with little change in Labor's vote but with the Playmander removed, Labor won 27 of 47 seats at the 1970 election. With a fairer seat and boundary system in place, Dunstan won three more elections, in 1973, 1975 and 1977.
