Input: Read this: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.
Question: What led to intermittent problems for the Khazars?

Output: unanswerable

QUES: Paper is often characterized by weight. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying "basic sizes", before the paper is cut into the size it is sold to end customers. For example, a ream of 20 lb, 8.5 in × 11 in (216 mm × 279 mm) paper weighs 5 pounds, because it has been cut from a larger sheet into four pieces. In the United States, printing paper is generally 20 lb, 24 lb, or 32 lb at most. Cover stock is generally 68 lb, and 110 lb or more is considered card stock.
What characteristic is paper usually classified by?

ANS: weight


Following Die Another Day, Madonna collaborated with fashion photographer Steven Klein in 2003 for an exhibition installation named X-STaTIC Pro=CeSS. It included photography from a photo shoot in W magazine, and seven video segments. The installation ran from March to May in New York's Deitch Projects gallery. It traveled the world in an edited form. The same year, Madonna released her ninth studio album, American Life, which was based on her observations of American society; it received mixed reviews. She commented, "[American Life] was like a trip down memory lane, looking back at everything I've accomplished and all the things I once valued and all the things that were important to me." Larry Flick from The Advocate felt that "American Life is an album that is among her most adventurous and lyrically intelligent" while condemning it as "a lazy, half-arsed effort to sound and take her seriously." The title song peaked at number 37 on the Hot 100. Its original music video was canceled as Madonna thought that the video, featuring violence and war imagery, would be deemed unpatriotic since America was then at war with Iraq. With four million copies sold worldwide, American Life was the lowest-selling album of her career at that point.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): American Life reached which number at the Hot 100?
Ah, so.. 37


Question: The language of treaties, like that of any law or contract, must be interpreted when the wording does not seem clear or it is not immediately apparent how it should be applied in a perhaps unforeseen circumstance. The Vienna Convention states that treaties are to be interpreted "in good faith" according to the "ordinary meaning given to the terms of the treaty in their context and in the light of its object and purpose." International legal experts also often invoke the 'principle of maximum effectiveness,' which interprets treaty language as having the fullest force and effect possible to establish obligations between the parties.
Try to answer this question if possible: What principle is often invoked by legal experts when interpreting the language of treaties?
Answer: principle of maximum effectiveness


Problem: The calendar was a refinement to the Julian calendar amounting to a 0.002% correction in the length of the year. The motivation for the reform was to bring the date for the celebration of Easter to the time of the year in which it was celebrated when it was introduced by the early Church. Because the celebration of Easter was tied to the spring equinox, the Roman Catholic Church considered the steady drift in the date of Easter caused by the year being slightly too long to be undesirable. The reform was adopted initially by the Catholic countries of Europe. Protestants and Eastern Orthodox countries continued to use the traditional Julian calendar and adopted the Gregorian reform after a time, for the sake of convenience in international trade. The last European country to adopt the reform was Greece, in 1923.
What was the correction due to?
---
Answer:
length of the year
