Question

which of the following does the graph best demonstrate about how humans should approach energy usage in the future to achieve maximum effectiveness?
a usage of renewable sources of energy will increase, so further funding for research into other forms of alternative energy should be decreased.
b coal consumption will continue to decline, so there should be continued efforts to mine and use more of it.
c fossil fuels will continue to be a significant part of energy usage, so increased efforts in conservation should be emphasized.
d nuclear energy usage will not increase, so further research into better nuclear waste management will not be needed.

Explanation:

By observing the graph trends of different energy - types over time, we can analyze the future approach to energy usage. If the usage of renewable energy sources is expected to increase as indicated by the graph, it implies that further funding for research into other forms of alternative energy may be decreased. Other options do not align well with the graph trends. For example, coal consumption does not show a continuous decline as stated in option B, fossil fuels' long - term trend does not suggest a need for increased conservation as in option C, and nuclear energy usage trend does not support the claim in option D.

Answer:

A. Usage of renewable sources of energy will increase, so further funding for research into other forms of alternative energy should be decreased
