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: When was the Rear-Admiral that was first assigned the Orion born? Passage:Orion, named after the mythological hunter, Orion, was the fourth ship of her name to serve in the Royal Navy (RN). The ship was laid down at HM Dockyard, Portsmouth on 29 November 1909. She was launched on 20 August 1910, and was commissioned on 2 January 1912. Including her armament, her cost is variously quoted at £1,855,917 or £1,918,773. Orion was assigned to the 2nd division of the Home Fleet as the flagship of Rear-Admiral Sir Herbert King-Hall, the division's second-in-command. The ship was slightly damaged on 7 January when the pre-dreadnought battleship broke loose from her moorings and collided with Orions bow. The division was redesignated as the 2nd Battle Squadron (BS) on 1 May. The ship, together with her sister ships and , participated in the Parliamentary Naval Review on 9 July at Spithead. They then participated in training manoeuvres. King-Hall was relieved by Rear-Admiral Rosslyn Wemyss on 29 October. On 13 November, the ship participated in comparative gunnery trials with Thunderer to evaluate the effectiveness of the latter's gunnery director. Thunderer decisively outshot Orion, although some of her success was because her director was above the smoke that obscured the target from Orions guns. The test was repeated in better conditions on 4 December and Orion performed much better, apparently beating Thunderer. The three sisters were present with the 2nd BS to receive the President of France, Raymond Poincaré, at Spithead on 24 June 1913 and then participated in the annual fleet manoeuvres in August. Wemyss was relieved in his turn by Rear-Admiral Sir Robert Arbuthnot, 4th Baronet on 28 October. Captain Frederic Dreyer assumed command of Orion that same day. On 4 November, Orion, Thunderer, the dreadnought and the predreadnought fired at and sank the target ship to give their crews experience in firing live ammunition against a real ship.
