Problem:Question: In what year was the coach whom Laperriere worked under in 1981 born? Passage 1:After retiring, Laperriere became the coach of the Montreal Juniors in 197576. He would resign the following year due to his distaste of the pressure and violence at the amateur level. In 198081, Laperriere rejoined the Canadiens organization as an assistant coach to Claude Ruel. He would stay as the Canadiens assistant coach for 16 years, serving under six different head coaches, and winning two Stanley Cups in 198586 and in 199293. In 199798, Laperriere joined the Boston Bruins staff, serving under Pat Burns as an assistant coach again. He spent four seasons in Boston before joining the New York Islanders in 200102. After two seasons with the Islanders, Laperriere became a part of the New Jersey Devils organization in 200304. Once again, Laperriere served as an assistant coach until 200607 when he was named a special assignment coach for the Devils.
Passage 2:The scientific botanical name with the standard spelling sabiniana commemorates Joseph Sabine, secretary of the Horticultural Society of London. In botanical nomenclature it is no longer customary to Latinize species names (such as Sabine to sabinius and sabiniana) before forming Neo-Latin terms, so an orthographical correction was proposed from sabiniana to sabineana by some botanists. However the new spelling proposal has not been accepted by the United States Department of Agriculture (USDA) National Plant Data Center or the University of California's "The Jepson Manual". Nor has it been adopted into general use, with the spelling sabiniana used in the pine's endemic range by the University of California and state agencies, and in its home country's U.S. federal agencies. The USDA's Germplasm Resources Information Network (GRIN) database notes that the spelling sabiniana agrees with a provision in the Vienna Code of the International Code of Botanical Nomenclature, the governing body of botanical nomenclature. In that Code, Recommendation 60.2C states that personal names that are already in Latin or Greek, or those that have a well-established Latinized form can remain Latinized in species epithets, otherwise species epithets must be orthographically corrected to the proper form. The GRIN database notes that Sabine's last name is not correctable and therefore Pinus sabiniana is the proper name for the species.
Passage 3:This plan was short-lived, and on 23 August 1943, the divisional headquarters, under Milford moved to the north coast of New Guinea, to take over the Salamaua campaign in its final stages. Landing at Nassau Bay, the headquarters took over from the 3rd Division and assumed control of its subordinate troops: the Australian 15th, 17th and 29th Brigades, and the US 162nd Infantry Regiment. The division occupied Salamaua on 11 September. After this, the division moved to Lae, which had been captured by the 7th Division, and between September 1943 and February 1944, its headquarters assumed the designation of HQ Lae Fortress, as the area was developed as a base for further operations around the Huon Peninsula and in the Ramu Valley. The division also undertook mopping up operations, securing small pockets of Japanese defenders left behind. By this time, the division reported to II Corps, and had adopted the jungle divisional establishment. After being re-designated once again as the 5th Division, the headquarters moved to Finschafen, assuming control of the 4th and 8th Brigades, and taking over the advance along the Rai coast towards Madang, which was secured in April 1944. Throughout the coming months, the 15th Brigade was reassigned to the division, as was the 7th Brigade, although both the 15th and 4th Brigades were returned to Australia in July and August 1944.
