Here is a question about this article: The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.

Here is a question about this article: The origin of the word antenna relative to wireless apparatus is attributed to Italian radio pioneer Guglielmo Marconi. In the summer of 1895, Marconi began testing his wireless system outdoors on his father's estate near Bologna and soon began to experiment with long wire "aerials". Marconi discovered that by raising the "aerial" wire above the ground and connecting the other side of his transmitter to ground, the transmission range was increased. Soon he was able to transmit signals over a hill, a distance of approximately 2.4 kilometres (1.5 mi). In Italian a tent pole is known as l'antenna centrale, and the pole with the wire was simply called l'antenna. Until then wireless radiating transmitting and receiving elements were known simply as aerials or terminals.
What is the answer to this question: Who is most associated with the emergence of the word antenna?

So... Guglielmo Marconi

Here is a question about this article: 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 is the answer to this question: What was Nasser's position on executing the rioter's leaders?
