Question

population growth rate, conservation tactic, years before population runs out of coal
none, none, 340
average, none, 150
average, build wind power plant, 175
average, build wind power plant and teach public energy conservation, 250
high, none, 100
a. conservation of coal resources can slow the rate of population growth.
b. conservation cannot make coal resources last longer for a population.
c. conservation can make coal a renewable resource for a population.

Explanation:

By looking at the table, when conservation tactics like building wind - power plants and teaching public energy conservation are implemented, the years before the population runs out of coal increase. This shows that conservation can make coal resources last longer. Coal is a non - renewable resource by nature and conservation does not change that. Also, there is no indication in the table that coal conservation affects population growth rate.

Answer:

None of the above options are correct. But if we had to analyze the given options:
A is incorrect as there is no evidence in the table that coal conservation affects population growth rate.
B is incorrect as the table shows that conservation tactics increase the years before running out of coal.
C is incorrect as coal is a non - renewable resource and conservation does not make it renewable.
