Problem: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
What is the result of using AC power on a DC motor?
The answer is the following: efficiency losses

The Sardinian language is considered to be its own Romance language family, separate not only from standard Italian but also the wider Italo-Dalmatian family, and it includes the Campidanese Sardinian and Logudorese Sardinian variants. However, Gallurese, Sassarese, and Corsican are also spoken in Sardinia, and these languages are considered closely related or derived from the Italian Tuscan language and thus are Italo-Dalmatian languages. Furthermore, the Gallo-Romance language of Ligurian and the Catalan Algherese dialect are also spoken in Sardinia.
What language family does Gallurese belong to?
Italo-Dalmatian

Article: Martin Luther, a German monk, started the German Reformation by posting 95 theses on the castle church of Wittenberg on October 31, 1517. The immediate provocation spurring this act was Pope Leo X's renewal of the indulgence for the building of the new St. Peter's Basilica in 1514. Luther was challenged to recant his heresy at the Diet of Worms in 1521. When he refused, he was placed under the ban of the Empire by Charles V. Receiving the protection of Frederick the Wise, he was then able to translate the Bible into German.

Question: What did Martin Luther post on the castle church of Wittenberg?
Ans: 95 theses

Input: Pain
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.

As of 2011, how many people worldwide are still denied access to inexpensive medications for severe pain?
Output:
tens of millions
