[Q]: Question: What is the maximum length of the species that is known to prey on the crossback stingaree? Passage:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 14 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.

He debuted with them in 1996, and he finished second to Todd Hollandsworth in Rookie of the Year Award balloting. In 1997, his RBI single off Charles Nagy in the eleventh inning of Game 7 of the 1997 World Series won the first World Series in Marlins' history. He was selected to his first All-Star Game in 1998, and he was traded to the St. Louis Cardinals following the season. He was the starting shortstop for the Cardinals for six years, and he was selected to the All-Star Game in 2000, 2003, and 2004. In 2002 and 2003 he won the Silver Slugger and Gold Glove Awards. Following the 2004 season, he signed with the Boston Red Sox. After a year with them, he was traded to the Atlanta Braves. He was selected to another All-Star Game in 2006, but following the 2007 season he was traded to the Detroit Tigers. After 2008, he became a free agent, and he signed with the San Francisco Giants. In the 2010 World Series, Renteria won the World Series Most Valuable Player Award after he hit game-winning home runs in Game 2 and Game 5. He became a free agent again after the season, and he signed with the Cincinnati Reds.

[Q]: Question: What years did the commander in chief of the armed forces that Crespo serve under rule? Passage:In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaulza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenco Marques where he would complete a number of academic disciplines but did not graduate. He also married Helen de Souza from Johannesburg, a South African woman with Portuguese ancestry who worked in genetics. After the Carnation Revolution left-leaning military coup at Lisbon in April 1974, fresh out of the troop, Crespo fled Mozambique for South Africa.
