Problem: Germany's high-altitude needs were originally going to be filled by a 75 mm gun from Krupp, designed in collaboration with their Swedish counterpart Bofors, but the specifications were later amended to require much higher performance. In response Krupp's engineers presented a new 88 mm design, the FlaK 36. First used in Spain during the Spanish Civil War, the gun proved to be one of the best anti-aircraft guns in the world, as well as particularly deadly against light, medium, and even early heavy tanks.
What war was the FlaK first used in?
The answer is the following: Spanish Civil War

Preceding the reform law, in August 1952, communist-led riots broke out at textile factories in Kafr el-Dawwar, leading to a clash with the army that left nine people dead. While most of the RCC insisted on executing the riot's two ringleaders, Nasser opposed this. Nonetheless, the sentences were carried out. The Muslim Brotherhood supported the RCC, and after Naguib's assumption of power, demanded four ministerial portfolios in the new cabinet. Nasser turned down their demands and instead hoped to co-opt the Brotherhood by giving two of its members, who were willing to serve officially as independents, minor ministerial posts.
What was Nasser's position on executing the rioter's leaders?
opposed

Here is a question about this article: Leibniz describes a space that exists only as a relation between objects, and which has no existence apart from the existence of those objects. Motion exists only as a relation between those objects. Newtonian space provided the absolute frame of reference within which objects can have motion. In Newton's system, the frame of reference exists independently of the objects contained within it. These objects can be described as moving in relation to space itself. For many centuries, the evidence of a concave water surface held authority.
What is the answer to this question: For how long did the evidence of a concave water surface hold authority in reference to space?
****
So...
many centuries
