Question: What is the definition of the Werther effect? Passage:In July 1994, two students of Taipei First Girls' High School committed suicide by charcoal-burning in a hotel in Su'ao, Yilan with a note that didn't state the reason clearly, even though that it was suspected in some mass media that they were a lesbian couple. In November 1998, a middle-aged woman in Hong Kong died by suicide using this method inside her small, sealed bedroom. She had a chemical engineering background. Hong Kong was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local mass media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. By 2001, it had surpassed hanging as the second most-common method of suicide in Hong Kong (second only to jumping), accounting for about 25% of all suicide deaths. The method has since spread to mainland China, Taiwan and Japan.
 Links: a. Hong Kong b. Jumper (person) c. Copycat suicide d. Chemical engineering

Question: What was the Hertford Town club record the year that Scott Neilson joined? Passage:Neilson was a member of Norwich City's youth teams at the age of 11, went on to Charlton Athletic and also won schoolboy honours for Wales. His senior career started at his brother Tony's club Hertford Town of the Isthmian League in 2005. He was top goalscorer for the reserves when he made his debut on 25 October in an Isthmian League Associate Members Trophy game against Clapton, before going on to play 15 games in his first season and scoring one goal. In his second season, he played 24 games upping his goal tally by another nine, before he earned a move in December 2006 to Ware – a second club where his brother also played. In one game in January 2008, Neilson came off the bench to score four goals for Ware against Tilbury in a 5–2 victory. The goals went towards Neilson's total of 23 from 40 games for Ware in the Isthmian League First Division North, helping Ware towards the end-of-season play-offs. However, he left Ware before the end of the season to join Cambridge City in March 2008 for the rest of the club's Conference South campaign.

Question: What year was the man who implemented the 46 calendar reform born? Passage:For superstitious reasons, when the Romans began to intercalate to bring their calendar into line with the solar year, they chose not to place their extra month of Mercedonius after February but within it. February 24—known in the Roman calendar as "the sixth day before the Kalends of March"—was replaced by the first day of this month since it followed Terminalia, the festival of the Roman god of boundaries. After the end of Mercedonius, the rest of the days of February were observed and the new year began with the first day of March. The overlaid religious festivals of February were so complicated that Julius Caesar opted not to change it at all during his 46 calendar reform. The extra day of his system's leap years were located in the same place as the old intercalary month but he opted to ignore it as a date. Instead, the sixth day before the Kalends of March was simply said to last for 48 hours and all the other days continued to bear their original names. (The Roman practice of inclusive counting initially caused the priests in charge of the calendar to add the extra hours every three years instead of every four and Augustus was obliged to omit them for a span of decades until the system was back to where it should have been.) When the extra hours finally began to be reckoned as two separate days instead of a doubled sixth ("bissextile") one, the leap day was still taken to be the one following hard on the February 23 Terminalia. Although February 29 has been popularly understood as the leap day of leap years since the beginning of sequential reckoning of the days of months in the late Middle Ages, in Britain and most other countries, no formal replacement of February 24 as the leap day of the Julian and Gregorian calendars has occurred. The exceptions include Sweden and Finland, who enacted legislation to move the day to February 29. This custom still has some effect around the world, for example with respect to name days in Hungary.
 Links: a. Name days in Hungary b. Terminalia c. Julius Caesar d. Terminalia
