Answer:
I think ... maybe ... dog and wolf?
Explanation:
because dog is just the domesticated version of wolf, then this may be possible - but this is just a very basic answer. other answers like chicken and dinosaur may be true as well depending on how specific your question is.
The correct answers are:
A) Nonrenewable resources create terrible pollution problems;
D) Once nonrenewable resources are used, they cannot be replaced, so we are not able to acquire more;
The nonrenewable resources are by far the most used resources across the globe. From side they are relatively cheap and are very efficient, but from the other side they are the biggest polluters and their reserves are becoming less and less. Being the biggest polluters, this resources create a lot of problems like the bad air quality, acid rains, and the climate change. Also, this resources are limited, so once the reserves of them are spent there will be no more of them, thus the humanity will be in big trouble if a proper solution is not found until then.
