Input: Read this: Greece is today relatively homogeneous in linguistic terms, with a large majority of the native population using Greek as their first or only language. Among the Greek-speaking population, speakers of the distinctive Pontic dialect came to Greece from Asia Minor after the Greek genocide and constitute a sizable group. The Cappadocian dialect came to Greece due to the genocide as well, but is endangered and is barely spoken now. Indigenous Greek dialects include the archaic Greek spoken by the Sarakatsani, traditionally transhument mountain shepherds of Greek Macedonia and other parts of Northern Greece. The Tsakonian language, a distinct Greek language deriving from Doric Greek instead of Ionic Greek, is still spoken in some villages in the southeastern Peloponnese.
Question: What is the language spoken by most Greeks?

Output: Greek

QUES: The state has one city with a population exceeding one million: Ciudad Juarez. Ciudad Juarez is ranked eighth most populous city in the country and Chihuahua City was ranked 16th most populous in Mexico. Chihuahua (along with Baja California) is the only state in Mexico to have two cities ranked in the top 20 most populated. El Paso and Ciudad Juarez comprise one of the largest binational metropolitan areas in the world with a combined population of 2.4 million. In fact, Ciudad Juarez is one of the fastest growing cities in the world in spite of the fact that it is "the most violent zone in the world outside of declared war zones". For instance, a few years ago the Federal Reserve Bank of Dallas published that in Ciudad Juarez "the average annual growth over the 10-year period 19902000 was 5.3 percent. Juarez experienced much higher population growth than the state of Chihuahua and than Mexico as a whole". Chihuahua City has one of the highest literacy rates in the country at 98%; 35% of the population is aged 14 or below, 60% 15-65, and 5% over 65. The growth rate is 2.4%. The 76.5% of the population of the state of Chihuahua live in cities which makes the state one of the most urbanized in Mexico.
Which city in the state exceeds one million?

ANS: Ciudad Juarez

At the start of her reign Victoria was popular, but her reputation suffered in an 1839 court intrigue when one of her mother's ladies-in-waiting, Lady Flora Hastings, developed an abdominal growth that was widely rumoured to be an out-of-wedlock pregnancy by Sir John Conroy. Victoria believed the rumours. She hated Conroy, and despised "that odious Lady Flora", because she had conspired with Conroy and the Duchess of Kent in the Kensington System. At first, Lady Flora refused to submit to a naked medical examination, until in mid-February she eventually agreed, and was found to be a virgin. Conroy, the Hastings family and the opposition Tories organised a press campaign implicating the Queen in the spreading of false rumours about Lady Flora. When Lady Flora died in July, the post-mortem revealed a large tumour on her liver that had distended her abdomen. At public appearances, Victoria was hissed and jeered as "Mrs. Melbourne".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What lady in waiting was at the heart of a 1839 court scandal?
Ah, so.. Lady Flora Hastings

Question: Historically, AC motors were used for single or double speed elevator machines on the grounds of cost and lower usage applications where car speed and passenger comfort were less of an issue, but for higher speed, larger capacity elevators, the need for infinitely variable speed control over the traction machine becomes an issue. Therefore, DC machines powered by an AC/DC motor generator were the preferred solution. The MG set also typically powered the relay controller of the elevator, which has the added advantage of electrically isolating the elevators from the rest of a building's electrical system, thus eliminating the transient power spikes in the building's electrical supply caused by the motors starting and stopping (causing lighting to dim every time the elevators are used for example), as well as interference to other electrical equipment caused by the arcing of the relay contactors in the control system.
Try to answer this question if possible: What is a known advantage of the MG set?
Answer: electrically isolating the elevators from the rest of a building's electrical system

Input: Read this: The International Association for the Study of Pain advocates that the relief of pain should be recognized as a human right, that chronic pain should be considered a disease in its own right, and that pain medicine should have the full status of a specialty. It is a specialty only in China and Australia at this time. Elsewhere, pain medicine is a subspecialty under disciplines such as anesthesiology, physiatry, neurology, palliative medicine and psychiatry. In 2011, Human Rights Watch alerted that tens of millions of people worldwide are still denied access to inexpensive medications for severe pain.
Question: What is pain medicine often under disciplines like physiatry, neurology, etc?

Output:
subspecialty
