To meet growing energy needs in Ibernia, companies built more energy plants that burn

and innovation in the development of alternative energy and a decrease in the country's
reliance on fossil fuels.
Which of the following is an assumption on which the argument depends?
(A) The plants that burn oil, coal, and natural gas can easily be converted so that
they use "green" energy.
(B) The carbon tax will lead to the closure of many of the plants that burn oil, coal,
and natural gas.
(C) Ibernia's energy needs will continue to grow even if the carbon tax results in
higher energy costs.
(D) Ibernia's reliance on fossil fuels is likely to cause the country to fall behind its
neighbors in efforts to develop "green" energy.
(E) The cost of developing alternative energy is less than the cost to existing energy
plants of the government's carbon tax.
GH-06.04.13
this one is straight E.
my pre-thought assumption -> cost of tax will be higher than cost of development. if not, then there is no certainty that the conclusion will hold true.
E exactly specifies this case.

Analyzing
A cannot be taken as we don't know from the passage about amount of effort required to convert to green energy
B is direct , nowhere states that Carbon tax will lead to closure of fossil plants (hence, ruled out)
C Ibernia's energy needs will continue to grow even if the carbon tax results in
higher energy costs. (??, Pre Energy Cost + C.Tax = Total Energy Cost)
Total Energy Cost > Pre Energy Cost ==> Cannot conclude if energy needs from Fossil Fuel will increase .
D Ibernia's reliance on fossil fuels is likely to cause the country to fall behind its
neighbors in efforts to develop "green" energy. ---straight out of context.
E The cost of developing alternative energy is less than the cost to existing energy
plants of the government's carbon tax.
Last paragraph--
We should therefore expect to see more money
and innovation in the development of alternative energy and a decrease in the country's
reliance on fossil fuels.
Possible only when --- option E hold true .
Cost(After Carbon Tax) > Cost (developing Alt. Energy )
