What does a purifier primarily do?

• A. A device that stores dirt
• B. A device that removes dirt or harmful substances
• C. A device that measures temperature
• D. A device that cleans floors

Answer: (B)

Purification means removing contaminants from the air or water to improve quality and safety. A purifier’s primary job is to remove dirt or harmful substances, often using filters or other purification methods. That’s why this option best fits. The other functions belong to different tools: storing dirt would imply a container or waste bin, measuring temperature to a thermometer, and cleaning floors to a mop or sweeper.
