Here is a question about this article: In 941, Igor led another major Rus' attack on Constantinople, probably over trading rights again. A navy of 10,000 vessels, including Pecheneg allies, landed on the Bithynian coast and devastated the Asiatic shore of the Bosphorus. The attack was well-timed, perhaps due to intelligence, as the Byzantine fleet was occupied with the Arabs in the Mediterranean, and the bulk of its army was stationed in the east. The Rus’ burned towns, churches, and monasteries, butchering the people and amassing booty. The emperor arranged for a small group of retired ships to be outfitted with Greek fire throwers and sent them out to meet the Rus’, luring them into surrounding the contingent before unleashing the Greek fire. Liutprand of Cremona wrote that "the Rus', seeing the flames, jumped overboard, preferring water to fire. Some sank, weighed down by the weight of their breastplates and helmets; others caught fire." Those captured were beheaded. The ploy dispelled the Rus’ fleet, but their attacks continued into the hinterland as far as Nicomedia, with many atrocities reported as victims were crucified and set up for use as targets. At last a Byzantine army arrived from the Balkans to drive the Rus' back, and a naval contingent reportedly destroyed much of the Rus' fleet on its return voyage (possibly an exaggeration since the Rus' soon mounted another attack). The outcome indicates increased military might by Byzantium since 911, suggesting a shift in the balance of power.
What is the answer to this question: How large was the fleet that attacked the Bithynian coast along with the Pecheneg allies?
****
So... 10,000 vessels


The problem: Answer a question about this article:
Incandescent bulbs have been replaced in many applications by other types of electric light, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, China, Canada and United States, are in the process of phasing out the use of incandescent light bulbs while others, including Colombia, Mexico, Cuba, Argentina, Brazil and Australia, have prohibited them already.
What does the acronym CFL refer to?
****
The answer: compact fluorescent lamps


Problem: Please answer a question about the following article about Nigeria:
On 24 March 2009, the Nigerian Federal Ministry of Science and Technology, NigComSat Ltd. and CGWIC signed another contract for the in-orbit delivery of the NigComSat-1R satellite. NigComSat-1R was also a DFH-4 satellite, and the replacement for the failed NigComSat-1 was successfully launched into orbit by China in Xichang on December 19, 2011. The satellite according to then-Nigerian President Goodluck Jonathan which was paid for by the insurance policy on NigComSat-1 which de-orbited in 2009, would have a positive impact on national development in various sectors such as communications, internet services, health, agriculture, environmental protection and national security.
What satellite did Nigeria's fourth satellite replace?
A: NigComSat-1

Problem: Critics argue Napoleon's true legacy must reflect the loss of status for France and needless deaths brought by his rule: historian Victor Davis Hanson writes, "After all, the military record is unquestioned—17 years of wars, perhaps six million Europeans dead, France bankrupt, her overseas colonies lost." McLynn notes that, "He can be viewed as the man who set back European economic life for a generation by the dislocating impact of his wars." However, Vincent Cronin replies that such criticism relies on the flawed premise that Napoleon was responsible for the wars which bear his name, when in fact France was the victim of a series of coalitions which aimed to destroy the ideals of the Revolution.
Which historian describes Napoleon's legacy in terms of years spent at war, numbers of European dead, and France's bankruptcy and loss of colonies?
The answer is the following: Victor Davis Hanson


Input: Article: Various theories for the decline of the Native American populations emphasize epidemic diseases, conflicts with Europeans, and conflicts among warring tribes. Scholars now believe that, among the various contributing factors, epidemic disease was the overwhelming cause of the population decline of the American natives. Some believe that after first contacts with Europeans and Africans, Old World diseases caused the death of 90 to 95% of the native population of the New World in the following 150 years. Smallpox killed up to one third of the native population of Hispaniola in 1518. By killing the Incan ruler Huayna Capac, smallpox caused the Inca Civil War. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, measles in 1618—all ravaged the remains of Inca culture.

Now answer this question: What disease killed almost a third of the population of Hispaniola in 1518?

Output:
Smallpox
