Question: Passage: SVCD has two-thirds the resolution of DVD, and over 2.7 times the resolution of VCD. One CD-R disc can hold up to 60 minutes of standard quality SVCD-format video. While no specific limit on SVCD video length is mandated by the specification, one must lower the video bit rate, and therefore quality, to accommodate very long videos. It is usually difficult to fit much more than 100 minutes of video onto one SVCD without incurring significant quality loss, and many hardware players are unable to play video with an instantaneous bit rate lower than 300 to 600 kilobits per second.

Answer: How much can a VCD hold?

Question: Passage: Everton's biggest rivalry is with neighbours Liverpool, against whom they contest the Merseyside derby. The Merseyside derby is usually a sellout fixture, and has been known as the "friendly derby" because both sets of fans can often be seen side by side red and blue inside the stadium both at Anfield and Goodison Park. Recently on the field, matches tend to be extremely stormy affairs; the derby has had more red cards than any other fixture in Premiership history. The rivalry stems from an internal dispute between Everton officials and the owners of Anfield, which was then Everton's home ground, resulting in Everton moving to Goodison Park, and the subsequent formation of Liverpool F.C., in 1892.

Answer:
In what year was the Merseyside derby first held?
