Problem: Please answer a question about the following article about Geological history of Earth:
Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object with about 10% of the Earth's mass impacting the planet in a glancing blow. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
Ice from what source helped to create earths oceans?
A: comets

Von Neumann is credited with the equilibrium strategy of mutual assured destruction, providing the deliberately humorous acronym, MAD. (Other humorous acronyms coined by von Neumann include his computer, the Mathematical Analyzer, Numerical Integrator, and Computer—or MANIAC). He also "moved heaven and earth" to bring MAD about. His goal was to quickly develop ICBMs and the compact hydrogen bombs that they could deliver to the USSR, and he knew the Soviets were doing similar work because the CIA interviewed German rocket scientists who were allowed to return to Germany, and von Neumann had planted a dozen technical people in the CIA. The Russians believed that bombers would soon be vulnerable, and they shared von Neumann's view that an H-bomb in an ICBM was the ne plus ultra of weapons, and they believed that whoever had superiority in these weapons would take over the world, without necessarily using them. He was afraid of a "missile gap" and took several more steps to achieve his goal of keeping up with the Soviets:

What was the goal of MAD?
Answer: quickly develop ICBMs and the compact hydrogen bombs that they could deliver to the USSR


Problem: This period of renewed assertiveness came to a calamitous end in May 1683 when Grand Vizier Kara Mustafa Pasha led a huge army to attempt a second Ottoman siege of Vienna in the Great Turkish War of 1683–1687. The final assault being fatally delayed, the Ottoman forces were swept away by allied Habsburg, German and Polish forces spearheaded by the Polish king Jan III Sobieski at the Battle of Vienna. The alliance of the Holy League pressed home the advantage of the defeat at Vienna, culminating in the Treaty of Karlowitz (26 January 1699), which ended the Great Turkish War. The Ottomans surrendered control of significant territories, many permanently. Mustafa II (1695–1703) led the counterattack of 1695–96 against the Habsburgs in Hungary, but was undone at the disastrous defeat at Zenta (in modern Serbia), 11 September 1697.
Which polish king led the fight against the Ottoman empire in the Battle of Vienna?
The answer is the following: Jan III Sobieski

Here is a question about this article: In central and northern Italy and in Flanders, the rise of towns that were to a degree self-governing stimulated economic growth and created an environment for new types of trade associations. Commercial cities on the shores of the Baltic entered into agreements known as the Hanseatic League, and the Italian Maritime republics such as Venice, Genoa, and Pisa expanded their trade throughout the Mediterranean.[V] Great trading fairs were established and flourished in northern France during the period, allowing Italian and German merchants to trade with each other as well as local merchants. In the late 13th century new land and sea routes to the Far East were pioneered, famously described in The Travels of Marco Polo written by one of the traders, Marco Polo (d. 1324). Besides new trading opportunities, agricultural and technological improvements enabled an increase in crop yields, which in turn allowed the trade networks to expand. Rising trade brought new methods of dealing with money, and gold coinage was again minted in Europe, first in Italy and later in France and other countries. New forms of commercial contracts emerged, allowing risk to be shared among merchants. Accounting methods improved, partly through the use of double-entry bookkeeping; letters of credit also appeared, allowing easy transmission of money.
What is the answer to this question: Who wrote The Travels of Marco Polo?
****
So...
Marco Polo
