Firefighters are often asked to speak to school and community groups about the importance of fire safety, particularly fire prevention and detection. Because smoke detectors reduce the risk of dying in a fire by half, firefighters often provide audiences with information on how to install these protective devices in their homes. Specially, they tell them these things: A smoke detector should be placed on each floor of a home. While sleeping people are in particular danger of an emergent fire, and there must be a detector outside each sleeping area. A good site for a detector would be a hallway that runs between living spaces and bedrooms. Because of the dead-air space that might be missed by turbulent hot air bouncing around above a fire, smoke detectors should be installed either on the ceiling at least four inches from the nearest wall, or high on a wall at least four, but no further than twelve inches from the ceiling. Detectors should not be mounted near windows, exterior doors, or other places where drafts might direct the smoke away from the unit. Nor should they be placed in kitchens and garages, where cooking and gas fumes are likely to cause false alarms.
The passage indicates that one of the responsibilities of a firefighter is to.
Speak to school groups about the importance of preventing fires.
The correct answer is Speak to school groups about the importance of preventing fires.
The question asks which duty the passage actually attributes to a firefighter, so the answer must be one the text directly states. The passage says that firefighters are frequently invited to speak to school and community groups about the importance of fire safety, particularly fire prevention and detection. The option about speaking to school groups on the importance of preventing fires matches this statement almost word for word, so it is supported.
The option about installing smoke detectors in residents' homes is not backed by the passage: the installation guidance is addressed to homeowners themselves, not presented as a task performed by firefighters.
The option about checking homes to verify that detectors are properly installed is likewise never mentioned; no inspection duty is described.
The option about developing formal fire-safety programmes for community leaders and school teachers distorts the text — the passage has firefighters speaking to such audiences about fire safety, not designing structured programmes for leaders and teachers.
Hence the answer is: speak to school groups about the importance of preventing fires.
