Question: How old were Norman Tindale and Joseph Birdsell when they published their paper about the 12 Negrito tribes? Passage:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.

Question: Which of the places where the steam railcars were stationed is older? Passage:In addition to the joint railcars of 1903, the London Brighton and South Coast Railway directors asked their Chief Mechanical Engineer, Robert Billinton, to investigate the use of steam or petrol railcars on lightly used services. Billinton died in 1904, before examples could be acquired, but in 1905 his successor Douglas Earle Marsh acquired two steam and two petrol railcars, for comparative purposes with small steam locomotives of the Stroudley A1 and D1 classes fitted for "motor train" or "push-pull" working. The steam railcars were built by Beyer, Peacock and Company and were of a similar design to those supplied by this company to the North Staffordshire Railway. They were stationed at Eastbourne and St Leonards and ran services on the East and West Sussex coast lines. They were both loaned to the War Department in 1918/19 before being sold to the Trinidad and Tobago government.

Question: How many people lived in Springfield the year that Strutt was baptised there? Passage:Strutt was baptised at Springfield, Essex, on 26 February 1762, the second son of John Strutt, of Terling Place, Essex, by Anne, daughter of the Rev. William Goodday of Maldon. Entering the army in 1778, he joined his regiment, the 61st, at Minorca. Later he was appointed to a company in the 91st, and took part in the defence of St. Lucia. In 1782, having exchanged into the 97th, he served at the siege of Gibraltar. On the signing of the preliminaries of peace he purchased a majority in the 60th regiment, and, being placed on half-pay, visited several German courts. In 1787 he was sent with his regiment to the West Indies, where he took an active part in military affairs. Succeeding to a lieutenant-colonelcy by special command of George III, he was removed to the 54th, and went with the army of Lord Moira to Flanders. In 1794 he bore a very distinguished part against the French at Tiel, going through much hard fighting. On his return he was sent to St. Vincent, where he was raised to the rank of brigadier-general. In January 1796, with two hundred men, he attacked a force of twelve hundred, being himself thrice wounded, and losing his right leg. On his return to England he was received with marked favour by the king, and on 23 February 1796 was made deputy governor of Stirling Castle, afterwards serving upon the staff in Ireland. On 23 June 1798 he was raised to the rank of major-general, and on 13 May 1800 he was, as a reward for his services, appointed to the sinecure office of governor of Quebec, and he held that post until his death. He died at Tofts, Little Baddow, Essex, on 5 February 1848, having seen an exceptional amount of military service, both at home and abroad.
