Explanation:

First Question (What is the result of greenhouse gas emissions?):

Greenhouse gases trap heat in the atmosphere. Increased levels lead to global warming. Increased rainfall isn't a direct main result, reduced biodiversity is an indirect or secondary effect, and cleaner air is incorrect. So the correct option is b.

Water pollution is defined as the release of harmful substances into water bodies. Noise pollution is about sound, soil pollution about soil, air pollution about air. So the correct option is b.

Answer:

b. Global warming
