Here is a question about this article: Following the death of Grand Prince Igor in 945, his wife Olga ruled as regent in Kiev until their son Sviatoslav reached maturity (ca. 963). His decade-long reign over Rus' was marked by rapid expansion through the conquest of the Khazars of the Pontic steppe and the invasion of the Balkans. By the end of his short life, Sviatoslav carved out for himself the largest state in Europe, eventually moving his capital from Kiev to Pereyaslavets on the Danube in 969. In contrast with his mother's conversion to Christianity, Sviatoslav, like his druzhina, remained a staunch pagan. Due to his abrupt death in an ambush in 972, Sviatoslav's conquests, for the most part, were not consolidated into a functioning empire, while his failure to establish a stable succession led to a fratricidal feud among his sons, which resulted in two of his three sons being killed.
What is the answer to this question: When did Prince Igor past away?
****
So... 945

The problem: Answer a question about this article:
With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of "light fixture".
What is considered the earliest form of artificial lighting?
****
The answer: campfires or torches

Problem: Please answer a question about the following article about Digestion:
After some time (typically 12 hours in humans, 46 hours in dogs, 34 hours in house cats),[citation needed] the resulting thick liquid is called chyme. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. 95% of absorption of nutrients occurs in the small intestine. Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6 ~ 6.9. Some vitamins, such as biotin and vitamin K (K2MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Waste material is eliminated from the rectum during defecation.
Where does hyme go after the duodenum?
A: the small intestine

The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes. If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy. If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy. An alloy with four constituents is a quaternary alloy, while a five-part alloy is termed a quinary alloy. Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system. In this respect, all of the various forms of an alloy containing only two constituents, like iron and carbon, is called a binary system, while all of the alloy combinations possible with a ternary alloy, such as alloys of iron, carbon and chromium, is called a ternary system.

What is another name for solutes?
Answer: The secondary constituents

Problem: Eisenhower's goal to create improved highways was influenced by difficulties encountered during his involvement in the U.S. Army's 1919 Transcontinental Motor Convoy. He was assigned as an observer for the mission, which involved sending a convoy of U.S. Army vehicles coast to coast. His subsequent experience with encountering German autobahn limited-access road systems during the concluding stages of World War II convinced him of the benefits of an Interstate Highway System. Noticing the improved ability to move logistics throughout the country, he thought an Interstate Highway System in the U.S. would not only be beneficial for military operations, but provide a measure of continued economic growth. The legislation initially stalled in the Congress over the issuance of bonds to finance the project, but the legislative effort was renewed and the law was signed by Eisenhower in June 1956.
When did Eisenhower sign the law to create the Interstate Highway System?
The answer is the following: June 1956

Input: Article: President Franklin Roosevelt ordered General Douglas MacArthur in the Philippines to formulate a Pacific defence plan with Australia in March 1942. Curtin agreed to place Australian forces under the command of MacArthur who became Supreme Commander, South West Pacific. MacArthur moved his headquarters to Melbourne in March 1942 and American troops began massing in Australia. Enemy naval activity reached Sydney in late May 1942, when Japanese midget submarines launched a daring raid on Sydney Harbour. On 8 June 1942, two Japanese submarines briefly shelled Sydney's eastern suburbs and the city of Newcastle.

Now answer this question: Who ordered General MacArthur to make a defense plan with Australia?

Output:
President Franklin Roosevelt
