Read the following passage carefully and answer the question given below:
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.
Specifically, 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.
According to the passage, to cover every sleeping area, a smoke detector must always be placed

Outside all bedrooms in a home.

In all hallways of a home.
- D.
In kitchens where fires are most likely to start.
Show answer & explanation
Correct answer: B
Concept
In literal reading comprehension, the best choice preserves the passage’s stated scope. Quantifiers such as each, all, and at least one matter because they determine whether a location rule covers every required sleeping area.
Application
The passage requires a smoke detector on each floor of a home.
It also requires a detector outside each sleeping area, so the rule must cover every area where people sleep.
Among the offered locations, placing detectors outside all bedrooms satisfies that coverage requirement.
Placing one outside only one bedroom on a level does not guarantee coverage for the other sleeping areas.
Cross-check / Contrast
At least one bedroom on any level is narrower than the passage’s each-sleeping-area rule.
Every hallway is broader than the passage, which gives only a suitable hallway between living and sleeping spaces as an example.
A kitchen conflicts with the warning that cooking fumes can cause false alarms.
Result: The best-supported offered location is outside all bedrooms in a home.
