Problem: Text: In general, boxers are prohibited from hitting below the belt, holding, tripping, pushing, biting, or spitting. The boxer's shorts are raised so the opponent is not allowed to hit to the groin area with intent to cause pain or injury. Failure to abide by the former may result in a foul. They also are prohibited from kicking, head-butting, or hitting with any part of the arm other than the knuckles of a closed fist (including hitting with the elbow, shoulder or forearm, as well as with open gloves, the wrist, the inside, back or side of the hand). They are prohibited as well from hitting the back, back of the head or neck (called a ''rabbit-punch'') or the kidneys. They are prohibited from holding the ropes for support when punching, holding an opponent while punching, or ducking below the belt of their opponent (dropping below the waist of your opponent, no matter the distance between).

Problem: Text: A replacement for the king size Snickers bar was launched in the UK in 2004 and designed to conform to the September 2004 Food and Drink Federation (FDF) ''Manifesto for Food and Health''. Part of the FDF manifesto was seven pledges of action to encourage the food and drink industry to be more health conscious. Reducing portion size, clearer food labels, and reduction of the levels of fat, sugar, and salt were among the FDF pledges. Mars Incorporated pledged to phase out their king-size bars in 2005 and replace them with shareable bars. A Mars spokesman said: ''Our king-size bars that come in one portion will be changed so they are shareable or can be consumed on more than one occasion. The name king-size will be phased out.''
