Input: Geological history of Earth
The Ordovician Period started at a major extinction event called the Cambrian-Ordovician extinction events some time about 485.4 1.9 Ma. During the Ordovician the southern continents were collected into a single continent called Gondwana. Gondwana started the period in the equatorial latitudes and, as the period progressed, drifted toward the South Pole. Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them. Also, Avalonia broke free from Gondwana and began to head north toward Laurentia. The Rheic Ocean was formed as a result of this. By the end of the period, Gondwana had neared or approached the pole and was largely glaciated.

What continent fractured off Gondwana in the direction of Laurentia?
Output: Avalonia

Input: Article: As with previous USB versions, USB 3.0 ports come in low-power and high-power variants, providing 150 mA and 900 mA respectively, while simultaneously transmitting data at SuperSpeed rates. Additionally, there is a Battery Charging Specification (Version 1.2 December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission. The Battery Charging Specification requires that the physical ports themselves be capable of handling 5 A of current[citation needed] but limits the maximum current drawn to 1.5 A.

Now answer this question: What are the power variants in USB 3.0 ports?

Output: low-power and high-power

Article: Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative.

Question: What is the main cause for the bitterness in beer?
Ans: Hops

Here is a question about this article: During the 12th century, the institutions of central government, which had hitherto accompanied the royal English court as it moved around the country, grew in size and sophistication and became increasingly fixed in one place. In most cases this was Westminster, although the royal treasury, having been moved from Winchester, came to rest in the Tower. While the City of Westminster developed into a true capital in governmental terms, its distinct neighbour, the City of London, remained England's largest city and principal commercial centre, and it flourished under its own unique administration, the Corporation of London. In 1100, its population was around 18,000; by 1300 it had grown to nearly 100,000.
What is the answer to this question: Where was the royal treasury housed?
****
So... the Tower

The first degrees from the college were awarded in 1849. The university was expanded with new buildings to accommodate more students and faculty. With each new president, new academic programs were offered and new buildings built to accommodate them. The original Main Building built by Sorin just after he arrived was replaced by a larger "Main Building" in 1865, which housed the university's administration, classrooms, and dormitories. Beginning in 1873, a library collection was started by Father Lemonnier. By 1879 it had grown to ten thousand volumes that were housed in the Main Building.
In what year had the library at Notre Dame reach 10,000 books?
****
The answer: 1879

The problem: Answer a question about this article:
The stagnation and decline, Stephen Lee argues, was relentless after the death of Suleiman in 1566, interrupted by a few short revivals or reform and recovery. The decline gathered speed so that the Empire in 1699 was, "a mere shadow of that which intimidated East and West alike in 1566." Although there are dissenting scholars, most historians point to "degenerate Sultans, incompetent Grand Viziers, debilitated and ill-equipped armies, corrupt officials, avaricious speculators, grasping enemies, and treacherous friends." The main cause was a failure of leadership, as Lee argues the first 10 sultans from 1292 to 1566, with one exception, had performed admirably. The next 13 sultans from 1566 to 1703, with two exceptions, were lackadaisical or incompetent rulers, says Lee. In a highly centralized system, the failure at the center proved fatal. A direct result was the strengthening of provincial elites who increasingly ignored Constantinople. Secondly the military strength of European enemies grew stronger and stronger, while the Ottoman armies and arms scarcely improved. Finally the Ottoman economic system grew distorted and impoverished, as war caused inflation, world trade moved in other directions, and the deterioration of law and order made economic progress difficult.
In what year did Suleiman die?
****
The answer:
1566
