The British dealt with range measurement first, when it was realised that range was the key to producing a better fuse setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuse Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off.
What was the first model of HRF (Height Range Finder) used by the British?
Barr & Stroud UB2

Input: Age of Enlightenment
There were two distinct lines of Enlightenment thought: the radical enlightenment, inspired by the philosophy of Spinoza, advocating democracy, individual liberty, freedom of expression, and eradication of religious authority; and a second, more moderate variety, supported by Rene Descartes, John Locke, Christian Wolff, Isaac Newton and others, which sought accommodation between reform and the traditional systems of power and faith. Both lines of thought were opposed by the conservative Counter-Enlightenment.

The radical enlightenment was inspired by the philosophy of whom?

Article: Dowding was summoned to an Air Ministry conference on 17 October 1940 to explain the poor state of night defences and the supposed (but ultimately successful) "failure" of his daytime strategy. The criticism of his leadership extended far beyond the Air Council, and the Minister of Aircraft Production, Lord Beaverbrook, and Churchill themselves intimated their support was waning. While the failure of night defence preparation was undeniable, it was not the AOC's responsibility to accrue resources. The general neglect of the RAF until the late spurt in 1938 had left sparse resources to build defences. While it was permissible to disagree with Dowding's operational and tactical deployment of forces, the failure of the Government and Air Ministry to allot resources was ultimately the responsibility of the civil and military institutions at large. In the pre-war period, the Chamberlain Government stated that night defence from air attack should not take up much of the national effort and, along with the Air Ministry, did not make it a priority.

Question: Lord Beaverbrook and Churchill's support of Dowding was what?
Ans: waning

Here is a question about this article: Hyderabad's lakes and the sloping terrain of its low-lying hills provide habitat for an assortment of flora and fauna. The forest region in and around the city encompasses areas of ecological and biological importance, which are preserved in the form of national parks, zoos, mini-zoos and a wildlife sanctuary. Nehru Zoological Park, the city's one large zoo, is the first in India to have a lion and tiger safari park. Hyderabad has three national parks (Mrugavani National Park, Mahavir Harina Vanasthali National Park and Kasu Brahmananda Reddy National Park), and the Manjira Wildlife Sanctuary is about 50 km (31 mi) from the city. Hyderabad's other environmental reserves are: Kotla Vijayabhaskara Reddy Botanical Gardens, Shamirpet Lake, Hussain Sagar, Fox Sagar Lake, Mir Alam Tank and Patancheru Lake, which is home to regional birds and attracts seasonal migratory birds from different parts of the world. Organisations engaged in environmental and wildlife preservation include the Telangana Forest Department, Indian Council of Forestry Research and Education, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Animal Welfare Board of India, the Blue Cross of Hyderabad and the University of Hyderabad.
What is the answer to this question: Which environmental preserve in Hyderabad is known to be a home for migratory birds?
****
So... Patancheru Lake
