To give a POI, a debater who is in the round but on the opposing side of the current speaker may stand up and wait to be called on. If the speaker chooses to call on the debater, the speaker yields the floor for up to 15 seconds, and the debater may offer an argument towards or ask a question to the speaker.[3] POIs are important in British Parliamentary style, as it allows the first two factions to maintain their relevance during the course of the debate, and the last two factions to introduce their arguments early in the debate. The first and last minute of each speech is considered "protected time", during which no points of information may be offered.
