Input: Article: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).

Now answer this question: What are the variations in the text of witnesses known as?

Output: variant readings, or simply variants or readings.


Article: In 1998, after the return of Steve Jobs, Apple consolidated its multiple consumer-level desktop models into the all-in-one iMac G3, which became a commercial success and revitalized the brand. Since their transition to Intel processors in 2006, the complete lineup is entirely based on said processors and associated systems. Its current lineup comprises three desktops (the all-in-one iMac, entry-level Mac mini, and the Mac Pro tower graphics workstation), and four laptops (the MacBook, MacBook Air, MacBook Pro, and MacBook Pro with Retina display). Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.

Question: What all-in-one product was created in 1998 through Apple's consolidations?
Ans: iMac G3


Here is a question about this article: To unambiguously specify the date, dual dating or Old Style (O.S.) and New Style (N.S.) are sometimes used with dates. Dual dating uses two consecutive years because of differences in the starting date of the year, or includes both the Julian and Gregorian dates. Old Style and New Style (N.S.) indicate either whether the start of the Julian year has been adjusted to start on 1 January (N.S.) even though documents written at the time use a different start of year (O.S.), or whether a date conforms to the Julian calendar (O.S.) rather than the Gregorian (N.S.).
What is the answer to this question: What is the Old Style date mean?
****
So... Julian calendar


The problem: Answer a question about this article:
Many Nobel prizes have been awarded to Swiss scientists, for example to the world-famous physicist Albert Einstein in the field of physics who developed his Special relativity while working in Bern. More recently Vladimir Prelog, Heinrich Rohrer, Richard Ernst, Edmond Fischer, Rolf Zinkernagel and Kurt Wüthrich received Nobel prizes in the sciences. In total, 113 Nobel Prize winners in all fields stand in relation to Switzerland[note 11] and the Nobel Peace Prize has been awarded nine times to organisations residing in Switzerland.
How many total Nobel prizes were awarded to Swiss scientists?
****
The answer: 113


Problem: Please answer a question about the following article about Electric motor:
The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.
How does a brushless wound rotor achieve stability?
A: a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set


Question: Read this and answer the question

Shortly after he learned of the failure of Menshikov's diplomacy toward the end of June 1853, the Tsar sent armies under the commands of Field Marshal Ivan Paskevich and General Mikhail Gorchakov across the Pruth River into the Ottoman-controlled Danubian Principalities of Moldavia and Wallachia. Fewer than half of the 80,000 Russian soldiers who crossed the Pruth in 1853 survived. By far, most of the deaths would result from sickness rather than combat,:118–119 for the Russian army still suffered from medical services that ranged from bad to none.

Who commanded the armies across the Pruth River?
Answer:
Field Marshal Ivan Paskevich and General Mikhail Gorchakov
