Problem: Anti-aircraft warfare:

As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently. Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the "Red Baron" is believed to have been shot down by an anti-aircraft Vickers machine gun. When the war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft weapons would be based around heavy weapons attacking high-altitude targets and lighter weapons for use when they came to lower altitudes.

Heavy weapons shot at high-altitude targets and what shot at low-altitude targets?

A: lighter weapons

Problem: Until the 1980s, the governor of the Federal District was appointed by the Federal Government, and the laws of Brasilia were issued by the Brazilian Federal Senate. With the Constitution of 1988 Brasilia gained the right to elect its Governor, and a District Assembly (Camara Legislativa) was elected to exercise legislative power. The Federal District does not have a Judicial Power of its own. The Judicial Power which serves the Federal District also serves federal territories. Currently, Brazil does not have any territories, therefore, for now the courts serve only cases from the Federal District.
What does the District Assembly not have currently?

Having removed the monarchical government, Gaddafi proclaimed the foundation of the Libyan Arab Republic. Addressing the populace by radio, he proclaimed an end to the "reactionary and corrupt" regime, "the stench of which has sickened and horrified us all." Due to the coup's bloodless nature, it was initially labelled the "White Revolution", although was later renamed the "One September Revolution" after the date on which it occurred. Gaddafi insisted that the Free Officers' coup represented a revolution, marking the start of widespread change in the socio-economic and political nature of Libya. He proclaimed that the revolution meant "freedom, socialism, and unity", and over the coming years implemented measures to achieve this.
What was the name of the revolutionary group led by Gaddafi?
A: Free Officers

Context and question: About 30 people have been indicted for participating in genocide or complicity in genocide during the early 1990s in Bosnia.

Question: In the 1520s during the Protestant Reformation, the city, under the political guidance of Jacob Sturm von Sturmeck and the spiritual guidance of Martin Bucer embraced the religious teachings of Martin Luther. Their adherents established a Gymnasium, headed by Johannes Sturm, made into a University in the following century. The city first followed the Tetrapolitan Confession, and then the Augsburg Confession. Protestant iconoclasm caused much destruction to churches and cloisters, notwithstanding that Luther himself opposed such a practice. Strasbourg was a centre of humanist scholarship and early book-printing in the Holy Roman Empire, and its intellectual and political influence contributed much to the establishment of Protestantism as an accepted denomination in the southwest of Germany. (John Calvin spent several years as a political refugee in the city). The Strasbourg Councillor Sturm and guildmaster Matthias represented the city at the Imperial Diet of Speyer (1529), where their protest led to the schism of the Catholic Church and the evolution of Protestantism. Together with four other free cities, Strasbourg presented the confessio tetrapolitana as its Protestant book of faith at the Imperial Diet of Augsburg in 1530, where the slightly different Augsburg Confession was also handed over to Charles V, Holy Roman Emperor.
Is there an answer to this question: How many other cities joined Strasbourg at the Imperial Diet of Augsburg in 1530?

Answer: four
