	a) Consuming more frozen foods for convenience.		b) Opting for seasonal, locally grown produce.
	c) Buying individually packaged snacks for portion control.		d) Choosing imported exotic fruits over locally available ones.

Q.2	In an area facing increased soil erosion due to extreme weather events linked to climate change, farmers seek strategies to protect soil health. What practice aligns best with sustainable soil management in such conditions?
	a) Clearing land for larger-scale monoculture to simplify farming practices.		b) Implementing agroforestry systems to prevent soil erosion and maintain fertility.
	c) Relinquishing organic matter addition to soil for fear of further erosion.		d) Applying chemical pesticides extensively to eradicate soil-dwelling pests.

Q.3	Robert, an environmentally conscious individual, has recently initiated a practice of composting her food scraps and yard trimmings. He intends to utilise the resultant compost as soil enrichment for her garden beds, aiming to reduce dependency on commercial fertilisers and promote sustainable gardening practices.
