Problem: Hokkien:

Hokkien has one of the most diverse phoneme inventories among Chinese varieties, with more consonants than Standard Mandarin or Cantonese. Vowels are more-or-less similar to that of Standard Mandarin. Hokkien varieties retain many pronunciations that are no longer found in other Chinese varieties. These include the retention of the /t/ initial, which is now /t/ (Pinyin 'zh') in Mandarin (e.g. 'bamboo' is tik, but zhu in Mandarin), having disappeared before the 6th century in other Chinese varieties.

Problem: YouTube:

YouTube offers users the ability to view its videos on web pages outside their website. Each YouTube video is accompanied by a piece of HTML that can be used to embed it on any page on the Web. This functionality is often used to embed YouTube videos in social networking pages and blogs. Users wishing to post a video discussing, inspired by or related to another user's video are able to make a "video response". On August 27, 2013, YouTube announced that it would remove video responses for being an underused feature. Embedding, rating, commenting and response posting can be disabled by the video owner.

What does the HMTL piece that accompanies each video do?

A: unanswerable

Problem: Queen (band):

The group's second LP, Queen II, was released in 1974, and features rock photographer Mick Rock's iconic image of the band on the cover. This image would be used as the basis for the 1975 "Bohemian Rhapsody" music video production. The album reached number five on the British album chart and became the first Queen album to chart in the UK. The Freddie Mercury-written lead single "Seven Seas of Rhye" reached number ten in the UK, giving the band their first hit. The album is the first real testament to the band's distinctive layered sound, and features long complex instrumental passages, fantasy-themed lyrics, and musical virtuosity. Aside from its only single, the album also included the song "The March of the Black Queen", a six-minute epic which lacks a chorus. The Daily Vault described the number as "menacing". Critical reaction was mixed; the Winnipeg Free Press, while praising the band's debut album, described Queen II as a "over-produced monstrosity". Allmusic has described the album as a favourite among the band's hardcore fans, and it is the first of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.

Who wrote the song Seven Seas of Rhye?

A: Freddie Mercury

Problem: Gregorian calendar:

The Gregorian calendar improves the approximation made by the Julian calendar by skipping three Julian leap days in every 400 years, giving an average year of 365.2425 mean solar days long. This approximation has an error of about one day per 3,300 years with respect to the mean tropical year. However, because of the precession of the equinoxes, the error with respect to the vernal equinox (which occurs, on average, 365.24237 days apart near 2000) is 1 day every 7,700 years, assuming a constant time interval between vernal equinoxes, which is not true. By any criterion, the Gregorian calendar is substantially more accurate than the 1 day in 128 years error of the Julian calendar (average year 365.25 days).

What is the approximate error for every 3,300 years?

A:
one day
