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.

Question: What did the emperor of Byzatine do to some of the old retired ships to help fight the Rus?
Ans: outfitted with Greek fire throwers


Article: Eisenhower returned to the U.S. in December 1939 and was assigned as a battalion commander and regimental executive officer of the 15th Infantry at Fort Lewis, Washington. In March 1941 he was promoted to colonel and assigned as chief of staff of the newly activated IX Corps under Major General Kenyon Joyce. In June 1941, he was appointed Chief of Staff to General Walter Krueger, Commander of the 3rd Army, at Fort Sam Houston in San Antonio, Texas. After successfully participating in the Louisiana Maneuvers, he was promoted to brigadier general on October 3, 1941. Although his administrative abilities had been noticed, on the eve of the U.S. entry into World War II he had never held an active command above a battalion and was far from being considered by many as a potential commander of major operations.

Question: In the spring of 1941, who commanded IX Corps?
Ans: Kenyon Joyce


Article: Neptune's orbit has a profound impact on the region directly beyond it, known as the Kuiper belt. The Kuiper belt is a ring of small icy worlds, similar to the asteroid belt but far larger, extending from Neptune's orbit at 30 AU out to about 55 AU from the Sun. Much in the same way that Jupiter's gravity dominates the asteroid belt, shaping its structure, so Neptune's gravity dominates the Kuiper belt. Over the age of the Solar System, certain regions of the Kuiper belt became destabilised by Neptune's gravity, creating gaps in the Kuiper belt's structure. The region between 40 and 42 AU is an example.

Question: What dominates the Kuiper belt? 
Ans: Neptune's gravity
