UGC NET Questions (Paper – 1)

Early warning systems detect impending hazards and communicate timely information so that people can take protective action. Cyclone alerts broadcast before landfall give communities time to evacuate or secure property. The stem clearly describes this function,so “early warning” is the correct term. It is a key component of disaster risk reduction.

Option A:
Recovery refers to restoring livelihoods and infrastructure after a disaster has occurred. It does not capture the advance information sharing described in the question.

Option B:
Response includes immediate rescue and relief activities during or just after impact. Although related,it is activated after the warning,not the warning itself.

Option C:
Mitigation involves long term measures that reduce the potential impact of hazards,such as embankments or building codes. It is different from the communication systems that warn people of imminent events.

Option D:
Early warning saves lives by turning risk information into action through effective communication and preparedness. This is exactly the role depicted in the question stem.
