Q: Question: Was the population of Canberra greater than that of Adelaide the year Burbidge was appointed assistant agronomist at Waite Agricultural Research Institute? Passage:In 1943 she was appointed assistant agronomist at the Waite Agricultural Research Institute in Adelaide, where she started working on native pasture species for arid and semi-arid South Australia. She was appointed to the new position of systematic botanist at the CSIRO Division of Plant Industry, Canberra in 1946. At CSIRO she worked on organising and extending the herbarium, first as a research scientist and then as curator and was responsible for laying the foundations of the Herbarium Australiense, later the National Australian Herbarium. She wrote Key to the South Australian species of Eucalyptus L'Hér. but had not specialised on the genus. Her professional interest in systemic botany was reflected by her tenure as secretary of the systematic botany committee of the Australian and New Zealand Association for the Advancement of Science from 1948 to 1952. She also edited Australasian Herbarium News until her until 1953, when she took a years leave to be the Australian Botanical Liaison Officer at the Kew Gardens herbarium. While at Kew she photographed and indexed type specimens of Australian plants and made microfilm copies of Robert Brown's notebooks for Australian herbaria.

Q: Question: How long had the civil war been underway when Gorges returned? Passage:His signature appears as a witness on a document dated 1629 claiming to be a deed for the sale of land by Indians to a group of settlers led by John Wheelwright on the south side of the Piscataqua River in what is now New Hampshire. This document was alleged to be a forgery by 19th century historian James Savage, based in part on evidence that Vines was in England at the time of the sale. In 1630 he was definitely involved in the establishment of settlements around Cape Elizabeth, Maine as part of Gorges' efforts to establish the proprietary Province of Maine. Gorges did not receive a royal charter for the land and a commission as governor until 1639, at which time Gorges appointed his cousin Thomas as deputy governor. Thomas Gorges established the government of the colony, and in 1642 he and Vines led an exploratory expedition into the interior that reached as far as the White Mountains. Gorges returned to England in 1643 to fight in the English Civil War. Government of the colony devolved to a council, which elected Vines deputy governor in 1644. Vines governed until 1645, during which time the colony was involved in conflicting land claims of the Lygonia territory administered by George Cleeve.
