Input: Read this: However, the problem of deflection settings — 'aim-off' — required knowing the rate of change in the target's position. Both France and UK introduced tachymetric devices to track targets and produce vertical and horizontal deflection angles. The French Brocq system was electrical, the operator entered the target range and had displays at guns; it was used with their 75 mm. The British Wilson-Dalby gun director used a pair of trackers and mechanical tachymetry; the operator entered the fuse length, and deflection angles were read from the instruments.
Question: What did the tachymetric devices do?

Output: track targets and produce vertical and horizontal deflection angles


Input: Read this: Following speculation that Sony was working on a 'slim' model, Sony officially announced the PS3 CECH-2000 model on August 18, 2009, at the Sony Gamescom press conference. New features included a slimmer form factor, decreased power consumption, and a quieter cooling system. It was released in major territories by September 2009. As part of the release for the slim model, the console logo ceased using the "Spider-Man font" (the same font used for the title of Sony's Spider-Man 3) and the capitalized PLAYSTATION 3. It instead reverted to a more traditional PlayStation- and PlayStation 2-like 'PlayStation 3' logo with "PS3" imprinted on the console. Along with the redesigning of the console and logo, the boot screen of all consoles changed from "Sony Computer Entertainment" to "PS3 PlayStation 3", with a new chime and the game start splash screen being dropped. The cover art and packaging of games was also changed.
Question: What did Sony change about the PS3 games along with the packaging in 2008?

Output: unanswerable


Input: Read this: With the death of Zhengde and ascension of Jiajing, the politics at court shifted in favor of the Neo-Confucian establishment which not only rejected the Portuguese embassy of Fernão Pires de Andrade (d. 1523), but had a predisposed animosity towards Tibetan Buddhism and lamas. Evelyn S. Rawski, a professor in the Department of History of the University of Pittsburgh, writes that the Ming's unique relationship with Tibetan prelates essentially ended with Jiajing's reign while Ming influence in the Amdo region was supplanted by the Mongols.
Question: Evelyn S. Rawski claims that Ming's relationship with Tibetan prelates ended during who's reign?

Output: Jiajing


Input: Read this: The Norfolk Island Legislative Assembly decided to hold a referendum on the proposal. On 8 May 2015, voters were asked if Norfolk Islanders should freely determine their political status and their economic, social and cultural development, and to "be consulted at referendum or plebiscite on the future model of governance for Norfolk Island before such changes are acted upon by the Australian parliament". 68% out of 912 voters voted in favour. The Norfolk Island Chief Minister, Lisle Snell, said that "the referendum results blow a hole in Canberra's assertion that the reforms introduced before the Australian Parliament that propose abolishing the Legislative Assembly and Norfolk Island Parliament were overwhelmingly supported by the people of Norfolk Island".
Question: When did the Legislative Assembly of Norfolk Island vote regarding the proposed Australian reforms?

Output:
8 May 2015
