Input: Article: In conjunction with the system of months there is a system of weeks. A physical or electronic calendar provides conversion from a given date to the weekday, and shows multiple dates for a given weekday and month. Calculating the day of the week is not very simple, because of the irregularities in the Gregorian system. When the Gregorian calendar was adopted by each country, the weekly cycle continued uninterrupted. For example, in the case of the few countries that adopted the reformed calendar on the date proposed by Gregory XIII for the calendar's adoption, Friday, 15 October 1582, the preceding date was Thursday, 4 October 1582 (Julian calendar).

Now answer this question: Why is calculating the days of the Gregorian calendar not simple?

Output: irregularities

The problem: Answer a question about this article:
All signatories to the CPPCG are required to prevent and punish acts of genocide, both in peace and wartime, though some barriers make this enforcement difficult. In particular, some of the signatoriesnamely, Bahrain, Bangladesh, India, Malaysia, the Philippines, Singapore, the United States, Vietnam, Yemen, and former Yugoslaviasigned with the proviso that no claim of genocide could be brought against them at the International Court of Justice without their consent. Despite official protests from other signatories (notably Cyprus and Norway) on the ethics and legal standing of these reservations, the immunity from prosecution they grant has been invoked from time to time, as when the United States refused to allow a charge of genocide brought against it by former Yugoslavia following the 1999 Kosovo War.
Along with Cyprus, what other major signatory official protested the the immunity of others from prosecution of genocide?
****
The answer: Norway

Problem: Please answer a question about the following article about Russian language:
Russian is a Slavic language of the Indo-European family. It is a lineal descendant of the language used in Kievan Rus'. From the point of view of the spoken language, its closest relatives are Ukrainian, Belarusian, and Rusyn, the other three languages in the East Slavic group. In many places in eastern and southern Ukraine and throughout Belarus, these languages are spoken interchangeably, and in certain areas traditional bilingualism resulted in language mixtures, e.g. Surzhyk in eastern Ukraine and Trasianka in Belarus. An East Slavic Old Novgorod dialect, although vanished during the 15th or 16th century, is sometimes considered to have played a significant role in the formation of modern Russian. Also Russian has notable lexical similarities with Bulgarian due to a common Church Slavonic influence on both languages, as well as because of later interaction in the 19th20th centuries, although Bulgarian grammar differs markedly from Russian. In the 19th century, the language was often called "Great Russian" to distinguish it from Belarusian, then called "White Russian" and Ukrainian, then called "Little Russian".
Where is Surzhyk used?
A: eastern Ukraine
