Problem: Between April 1877 and February 1878, she threatened five times to abdicate while pressuring Disraeli to act against Russia during the Russo-Turkish War, but her threats had no impact on the events or their conclusion with the Congress of Berlin. Disraeli's expansionist foreign policy, which Victoria endorsed, led to conflicts such as the Anglo-Zulu War and the Second Anglo-Afghan War. "If we are to maintain our position as a first-rate Power", she wrote, "we must ... be Prepared for attacks and wars, somewhere or other, CONTINUALLY." Victoria saw the expansion of the British Empire as civilising and benign, protecting native peoples from more aggressive powers or cruel rulers: "It is not in our custom to annexe countries", she said, "unless we are obliged & forced to do so." To Victoria's dismay, Disraeli lost the 1880 general election, and Gladstone returned as prime minister. When Disraeli died the following year, she was blinded by "fast falling tears", and erected a memorial tablet "placed by his grateful Sovereign and Friend, Victoria R.I."
To whom did Queen Victoria dedicate a memorial after his death for grateful service?
The answer is the following: Disraeli

Problem: Louis did not leave a son as heir after his death in 1382. Instead, he named as his heir the young prince Sigismund of Luxemburg, who was 11 years old. The Hungarian nobility did not accept his claim, and the result was an internal war. Sigismund eventually achieved total control of Hungary and established his court in Buda and Visegrad. Both palaces were rebuilt and improved, and were considered the richest of the time in Europe. Inheriting the throne of Bohemia and the Holy Roman Empire, Sigismund continued conducting his politics from Hungary, but he was kept busy fighting the Hussites and the Ottoman Empire, which was becoming a menace to Europe in the beginning of the 15th century.
Upon taking the throne of Hungary where did Sigismund establish his court?
The answer is the following: Buda and Visegrad

Problem: Most Western languages (particularly those with writing systems based on the Latin, Cyrillic, Greek, Coptic, and Armenian alphabets) use letter cases in their written form as an aid to clarity. Scripts using two separate cases are also called bicameral scripts. Many other writing systems make no distinction between majuscules and minuscules a system called unicameral script or unicase. This includes most syllabic and other non-alphabetic scripts. The Georgian alphabet is special since it used to be bicameral, but today is mostly used in a unicameral way.
Which alphabet is a special case because it transitioned from bicameral to unicameral?
The answer is the following: Georgian

Problem: In 2013 and 2014, a Russian/Ukrainian hacking ring known as "Rescator" broke into Target Corporation computers in 2013, stealing roughly 40 million credit cards, and then Home Depot computers in 2014, stealing between 53 and 56 million credit card numbers. Warnings were delivered at both corporations, but ignored; physical security breaches using self checkout machines are believed to have played a large role. "The malware utilized is absolutely unsophisticated and uninteresting," says Jim Walter, director of threat intelligence operations at security technology company McAfee meaning that the heists could have easily been stopped by existing antivirus software had administrators responded to the warnings. The size of the thefts has resulted in major attention from state and Federal United States authorities and the investigation is ongoing.
What machines were involved in the physical security breaches that played a large role in the incident?
The answer is the following:
self checkout machines
