Help me with this question please

Only logical answer would be the third one: A temperate forest became a swamp.

Explanation:

A pond cannot become a lake unless human interaction was involved to dig around the pond and fill it in with water, making it a man made lake.

A forest can't become a desert. Come on.

And finally, and arctic region cannot become a tropical region because it would be too cold for trees, grass, animals (other than local animals like killer whales and polar bears) cannot thrive in the region.

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
