NHL Referee Open Book Exam

Explanation
In the NHL, the officiating system used is 2 Referees & 2 Linesmen. This means that there are two referees on the ice who are responsible for enforcing the rules of the game, making calls, and ensuring fair play. The two linesmen, on the other hand, are responsible for calling offside and icing infractions, as well as breaking up fights and maintaining order on the ice. Having two referees and two linesmen allows for better coverage of the game and helps ensure that all plays and infractions are properly observed and addressed.

Explanation
When a goal is scored and the buzzer sounds simultaneously, the call is to put the play under review to determine whether it is a goal or not. This is because the buzzer sounding at the same time as the goal may indicate that the play was made just before the time expired, and the review is necessary to ensure the goal was scored within the allowed time frame.

Explanation
When a goalie is pulled in a hockey game, it means that the team removes their goaltender from the ice and replaces them with an extra skater. This is typically done in the final minutes of a game when a team is trailing and needs to score a goal. By pulling their goalie, the team gains an extra man advantage on the ice, increasing their chances of scoring. Therefore, the statement is true.

Explanation
In this situation, the correct answer is to blow the whistle right away. This is because the player from team B has been illegally hit and is injured. Blowing the whistle will stop the game and allow the officials to assess the situation and provide necessary medical attention to the injured player. It is important to prioritize the safety and well-being of the players, and taking immediate action by blowing the whistle is the appropriate response in this case.

Explanation
In a typical ice hockey game, each team has six players on the ice at a time: one goaltender, two defensemen, and three forwards. This composition is known as a line. Teams can change their lines at any time during the game, which is often done to maintain the energy and effectiveness of the players, considering the high-intensity and fast-paced nature of the game. A team's full roster usually consists of between 17 and 22 players, including goaltenders, defensemen, and forwards, to allow for rotation and rest during the game.
