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).

Question: Why is calculating the days of the Gregorian calendar not simple?
Ans: irregularities

Article: During the tumultuous 14th century, disputes within the leadership of the Church led to the Avignon Papacy of 130578, also called the "Babylonian Captivity of the Papacy" (a reference to the Babylonian captivity of the Jews), and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states. Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417 the council elected Martin V (pope 141731) as pope.

Question: What is another term for the Avignon Papacy?
Ans: Babylonian Captivity of the Papacy

Article: The earliest known American lodges were in Pennsylvania. The Collector for the port of Pennsylvania, John Moore, wrote of attending lodges there in 1715, two years before the formation of the first Grand Lodge in London. The Premier Grand Lodge of England appointed a Provincial Grand Master for North America in 1731, based in Pennsylvania. Other lodges in the colony obtained authorisations from the later Antient Grand Lodge of England, the Grand Lodge of Scotland, and the Grand Lodge of Ireland, which was particularly well represented in the travelling lodges of the British Army. Many lodges came into existence with no warrant from any Grand Lodge, applying and paying for their authorisation only after they were confident of their own survival.

Question: Where were the earliest known American Logdes located?
Ans: Pennsylvania

Article: Although research has been inconclusive, some findings have indicated that electronic communication negatively affects adolescents' social development, replaces face-to-face communication, impairs their social skills, and can sometimes lead to unsafe interaction with strangers. A 2015 review reported that "adolescents lack awareness of strategies to cope with cyberbullying, which has been consistently associated with an increased likelihood of depression." Studies have shown differences in the ways the internet negatively impacts the adolescents' social functioning. Online socializing tends to make girls particularly vulnerable, while socializing in Internet cafes seems only to affect boys academic achievement. However, other research suggests that Internet communication brings friends closer and is beneficial for socially anxious teens, who find it easier to interact socially online. The more conclusive finding has been that Internet use has a negative effect on the physical health of adolescents, as time spent using the Internet replaces time doing physical activities. However, the Internet can be significantly useful in educating teens because of the access they have to information on many various topics.

Question: According to research findings, does Internet use have a positive or negative effect on teen physical health?
Ans:
negative
