The appropriate response is heart rates. A typical resting heart rate for grown-ups ranges from 60 to 100 pulsates a moment. By and large, a lower heart rate very still infers more productive heart capacity and better cardiovascular wellness. For instance, an all around prepared competitor may have an ordinary resting heart rate more like 40 thumps a moment.
The second alternative is correct (B).
The economic matrix in force in the world is based on the burning of fossil fuels, mainly petroleum, which releases amounts of CO2 and other gases in the ozone layer.
The acid rain is due to the exaggerated amount of products from the burning of fossil fuels released into the atmosphere. That is, human activities are mainly responsible for this phenomenon of acid rain.
Thus, the change to a clean energy matrix, using solar, wind and other energy, can result in a decrease in the phenomenon of acid rain.
I think the answer is B but I could be wrong
