Are two 'teams' stronger than one? This 'rotation' of judges means that Christina Aguilera and Cee Lo Green will return alongside Adam Levine and Blake Shelton for season 5 in the fall -- while Usher and Shakira will take season 6 in the spring of 2014.
A rule or rule set is a statement that tells browsers how to render particular elements on an HTML page. A rule set consists of a selector followed by a declaration block. The selector selects the elements on an HTML page that are affected by the rule set.
The maximum number of sets in a match is five for men and three for women. Usually the first player to win six games wins a set but if the score becomes five-games-all, one player must be two games ahead to win the set. So a player must win the set 7-5 or 8-6 or 9-7 and so on. Until the 1970s, this meant sets could potentially last indefinitely. But in 1971 the All England Club introduced the tie break rule.
