Answer 1

Answer:

A. i, iii

A heat wave is indeed characterized by prolonged, excessively hot and humid weather. Its intensity is relative to the typical climate of the region, meaning what is considered a heat wave in one area might be normal in another. Factors like stagnant air and poor air quality exacerbate the health risks, leading to illnesses such as heatstroke and dehydration, which can be life-threatening if not addressed promptly. Heat waves are becoming more frequent and intense globally due to climate change, posing significant public health challenges.
