True. According to the rules of Ultimate, if play is obstructed by non-players or objects within three (3) metres of the perimeter line, any obstructed player or thrower in possession may call "Violation."

False. According to the rules, if play is obstructed by non-players or objects within three (3) metres of the perimeter line, any obstructed player or thrower in possession may call "Violation." This means that not only the thrower but any player who is obstructed by non-players or objects close to the perimeter can make this call.

True. According to the rules of Ultimate, if play is obstructed by non-players or objects within three (3) metres of the perimeter line, any obstructed player or thrower in possession may call "Violation."

True. The goal lines are indeed part of the central zone. According to the rules of Ultimate, the goal lines separate the central zone from the end zones and are considered part of the central zone.

False. According to the rules of Ultimate, the perimeter lines are not part of the playing field. They surround the playing field and consist of two sidelines along the length and two endlines along the width, but they themselves are considered out-of-bounds.

The statement "The perimeter lines are part of the playing field" is incorrect according to the rules of Ultimate. Specifically, the perimeter lines, which consist of two sidelines along the length and two endlines along the width of the playing field, are not part of the playing field itself. This is clarified in the rules, which state that the entire playing field is in-bounds, but the perimeter lines are out-of-bounds. Therefore, the perimeter lines surround the playing field but are not included within it.

True. The goal lines are the lines that separate the central zone from the end zones and are part of the central zone.

Based on the rules of Ultimate, if Player A established possession of the pass in the central zone and not in the end zone, then a goal has not been scored. If there was a call of 'goal' and a discussion ensued which determined that Player A was in the central zone, then according to the rules, all players should return to where they were when the 'goal' call was made. This is because the 'goal' call is considered a stoppage of play, and the positions of the players should be reset to the state of the game at the time of the stoppage. Please note that the goal line is part of the central zone, not the end zone, so Player A would need to be in contact with the end zone, not just the goal line, to score a goal. Since the discussion resolved that Player A was in the central zone, the game should resume with Player A in possession of the disc in the central zone, and all other players returning to their positions at the time of the 'goal' call.

False. According to the rules of Ultimate, when executing a pull, the puller must have both feet completely within the end zone until the disc is released. If the puller has one foot in the central zone when the pull is released, it would be considered a violation of the rules.

False. According to the rules of Ultimate, the perimeter lines are not part of the playing field. They surround the playing field and consist of two sidelines along the length and two endlines along the width, but they themselves are considered out-of-bounds (source_reference 2.2 and 2.1).

True. According to the provided rules, the goal lines are indeed part of the central zone.

An end zone is one of the two areas at the end of the playing field in Ultimate Frisbee where teams can score a goal by catching the disc there. It is separated from the central zone by the goal line. The cones at the front and rear of the end zone along the sideline are relevant when a player is close to the sideline within the end zone. The end zone being attacked is the one in which the team is currently attempting to prevent the opposition from scoring.

The lines that are part of the field in Ultimate frisbee are the two sidelines along the length and the two endlines along the width.

The field in Ultimate frisbee is 100 meters long by 37 meters wide. It is divided into a central zone that is 64 meters long and two end zones that are 18 meters deep at each end of the central zone. The lines on the field should be between 75 and 120 millimeters wide and marked with a non-caustic material. If there is not enough space for a full-sized field, the end zones should be made shorter before reducing the central zone.

A brick call in Ultimate frisbee refers to a situation where an offensive player signals and calls "brick" after the pull. This call allows a different offensive player to pick up the disc instead. If there is a disagreement among players regarding whether the pull landed out-of-bounds or in-bounds, the midpoint on the sideline between the two proposed pivot locations should be used.
