Input: Article: The invasions brought new ethnic groups to Europe, although some regions received a larger influx of new peoples than others. In Gaul for instance, the invaders settled much more extensively in the north-east than in the south-west. Slavic peoples settled in Central and Eastern Europe and the Balkan Peninsula. The settlement of peoples was accompanied by changes in languages. The Latin of the Western Roman Empire was gradually replaced by languages based on, but distinct from, Latin, collectively known as Romance languages. These changes from Latin to the new languages took many centuries. Greek remained the language of the Byzantine Empire, but the migrations of the Slavs added Slavonic languages to Eastern Europe.

Now answer this question: People of what ethnicity settled in the Balkan Peninsula?

Output: Slavic


Article: Statistically speaking, cable-borne elevators are extremely safe. Their safety record is unsurpassed by any other vehicle system. In 1998, it was estimated that approximately eight millionths of one percent (1 in 12 million) of elevator rides result in an anomaly, and the vast majority of these were minor things such as the doors failing to open. Of the 20 to 30 elevator-related deaths each year, most of them are maintenance-related — for example, technicians leaning too far into the shaft or getting caught between moving parts, and most of the rest are attributed to other kinds of accidents, such as people stepping blindly through doors that open into empty shafts or being strangled by scarves caught in the doors. In fact, prior to the September 11th terrorist attacks, the only known free-fall incident in a modern cable-borne elevator happened in 1945 when a B-25 bomber struck the Empire State Building in fog, severing the cables of an elevator cab, which fell from the 75th floor all the way to the bottom of the building, seriously injuring (though not killing) the sole occupant — the elevator operator. However, there was an incident in 2007 at a Seattle children's hospital, where a ThyssenKrupp ISIS machine-room-less elevator free-fell until the safety brakes were engaged. This was due to a flaw in the design where the cables were connected at one common point, and the kevlar ropes had a tendency to overheat and cause slipping (or, in this case, a free-fall). While it is possible (though extraordinarily unlikely) for an elevator's cable to snap, all elevators in the modern era have been fitted with several safety devices which prevent the elevator from simply free-falling and crashing. An elevator cab is typically borne by 2 to 6 (up to 12 or more in high rise installations) hoist cables or belts, each of which is capable on its own of supporting the full load of the elevator plus twenty-five percent more weight. In addition, there is a device which detects whether the elevator is descending faster than its maximum designed speed; if this happens, the device causes copper (or silicon nitride in high rise installations) brake shoes to clamp down along the vertical rails in the shaft, stopping the elevator quickly, but not so abruptly as to cause injury. This device is called the governor, and was invented by Elisha Graves Otis. In addition, a oil/hydraulic or spring or polyurethane or telescopic oil/hydraulic buffer or a combination (depending on the travel height and travel speed) is installed at the bottom of the shaft (or in the bottom of the cab and sometimes also in the top of the cab or shaft) to somewhat cushion any impact. However, In Thailand, in November 2012, a woman was killed in free falling elevator, in what was reported as the "first legally recognised death caused by a falling lift".

Question: In the late nineties, what was considered the rate of cable-borne elevator problems? 
Ans: eight millionths of one percent (1 in 12 million) of elevator rides


Here is a question about this article: Most of the residents are Marshallese, who are of Micronesian origin and migrated from Asia several thousand years ago. A minority of Marshallese have some recent Asian ancestry, mainly Japanese. About one-half of the nation's population lives on Majuro, the capital, and Ebeye, a densely populated island. The outer islands are sparsely populated due to lack of employment opportunities and economic development. Life on the outer atolls is generally traditional.
What is the answer to this question: From what continent did the Marshallese originate?
****
So... Asia


The problem: Answer a question about this article:
Historical linguistics emerged as an independent field of study at the end of the 18th century. Sir William Jones proposed that Sanskrit, Persian, Greek, Latin, Gothic, and Celtic languages all shared a common base. After Jones, an effort to catalog all languages of the world was made throughout the 19th century and into the 20th century. Publication of Ferdinand de Saussure's Cours de linguistique générale created the development of descriptive linguistics. Descriptive linguistics, and the related structuralism movement caused linguistics to focus on how language changes over time, instead of just describing the differences between languages. Noam Chomsky further diversified linguistics with the development of generative linguistics in the 1950s. His effort is based upon a mathematical model of language that allows for the description and prediction of valid syntax. Additional specialties such as sociolinguistics, cognitive linguistics, and computational linguistics have emerged from collaboration between linguistics and other disciplines.
What did Sir William Jones do to document his work?
****
The answer: catalog all languages of the world


Problem: Please answer a question about the following article about Greece:
By 500 BC, the Persian Empire controlled the Greek city states in Asia Minor and had made territorial gains in the Balkans and Eastern Europe proper as well. Attempts by some of the Greek city-states of Asia Minor to overthrow Persian rule failed, and Persia invaded the states of mainland Greece in 492 BC, but was forced to withdraw after a defeat at the Battle of Marathon in 490 BC. A second invasion by the Persians followed in 480 BC. Despite a heroic resistance at Thermopylae by Spartans and other Greeks led by King Leonidas, and a simultaneous naval engagement at Artemisium,[page needed] Persian forces occupied Athens, which had been evacuated in time, as well as briefly overrunning half of Greece. Following decisive Greek victories in 480 and 479 BC at Salamis, Plataea, and Mycale, the Persians were forced to withdraw for a second time, marking their eventual withdrawal from all of their European territories. Led by Athens and Sparta, the Greek victories in the Greco-Persian Wars are considered a pivotal moment in world history, as the 50 years of peace that followed are known as Golden Age of Athens, the seminal period of ancient Greece that laid many of the foundations of Western civilization.
In 500 BC, Greece was ruled over by who?
A: Persian Empire


Question: Read this and answer the question

The Egyptian military has dozens of factories manufacturing weapons as well as consumer goods. The Armed Forces' inventory includes equipment from different countries around the world. Equipment from the former Soviet Union is being progressively replaced by more modern US, French, and British equipment, a significant portion of which is built under license in Egypt, such as the M1 Abrams tank.[citation needed] Relations with Russia have improved significantly following Mohamed Morsi's removal and both countries have worked since then to strengthen military and trade ties among other aspects of bilateral co-operation. Relations with China have also improved considerably. In 2014, Egypt and China have established a bilateral "comprehensive strategic partnership".

How many factories does Egyptian military have?
Answer:
dozens
