New coal-burning power plants are making moderate strides in environmental responsibility. Plants using an integrated gasification combined cycle (IGCC) utilize two distinct thermodynamic cycles, making them up to 15% more efficient than traditional coal-burning plants. In the first cycle, raw coal is converted into a synthetic gas, filtered to remove pollutants such as sulfur and nitrous oxide, and burned at high pressure to produce half the plant's electricity. Exhaust gases from the first cycle are captured and used to heat water, which turns a second turbine to generate another 125 megawatts. Newer plants are equipped with scrubbers to capture carbon dioxide and other greenhouse gas emissions, and older plants can be retrofitted to do the same. Since the IGCC system yields more energy per ton of coal and is also capable of capturing harmful emissions, constructing more coal-burning plants using this technology seems to be an energy solution to satisfy both industrial and environmental groups. However, "cleaner burning" coal plants are actually short-sighted, inadequate solutions to our current energy crisis because they ignore two grave environmental dangers. First, though coal may seem cheap economically, it is painfully expensive environmentally, as mining practices deplete land beyond recovery. In some eastern states, for example, mining companies have leveled entire mountains in their quest for coal. Experts estimate that strip-mining of sources in Appalachian forests is contaminating ground water and causing erosion that will eventually destroy several irreplaceable species. Additionally, though carbon dioxide is not released into the atmosphere by IGCC plants, it remains a by-product, which scientists must either develop a way to process or, as in an ill-considered current trend, find a place to store. A team investigating storage possibilities in a series of caverns under the Arctic Ocean floor estimates that the caverns are large enough to store the planet's carbon dioxide emissions for the next 600 years; so far they have found no evidence that the rock is leaking. If, however, the stored carbon dioxide leaks after only 50 years, the damage to the environment will be greater than if coal plants had continued operating with no emissions-capturing provisions. The primary purpose of the passage as a whole is to A. Account for the popularity of coal-burning power plants. B. Argue that coal-burning power plants may cause more environmental problems than they solve. C. Explain the dual thermodynamic cycles of IGCC coal plants. D. Plead for more efficient methods of reducing carbon emissions. E. Evaluate the economic feasibility of constructing more coal-burning power plants.

I did not quite understand the solution. I consider between C and E but end up with E.
I guess avoiding overstating the case is a stronger intention of 'seems' to be used in the sentence.

E is wrong because of 'the IGCC plants'? can u explain more

Hi,

May I know what made it feel like a poor quality question? What parts you found confusing/ not understandable?

I don’t quite agree with the solution. Again none of the answer choices are appealing

For option C
When the word "seems" is used the author is saying that ok this may be be a solution however there are short comings which need to be looked into This is not the same as "Cannot be trusted" This statement is too strong for it to be the correct answer.

I think you mean Option B (which is the correct answer)

Quote:

B. Argue that coal-burning power plants may cause more environmental problems than they solve.

The answer choice does not say “cannot be trusted”; it says “may” cause. Looking at the overall structure of the passage, the first paragraph introduces IGCC and explains how it is better than traditional plants. The subsequent paragraphs argue that IGCC plants ignore two grave environmental dangers. The author’s tone is not neutral, nor is he simply listing problems. Rather, he is arguing that this solution may create serious long-term dangers despite its short-term benefits. Moreover, none of the other answer choices comes close to capturing the primary purpose of the passage. That's why B is the correct answer.

Hope that helps!!

"technology seems to be an energy solution to satisfy both industrial and environmental groups."

This line in the passage made me feel that it is not by an environmental group, because why would an environmental group refer to themselves as seemingly finding this to be a satisfactory solution?

Any thoughts?

Hi dignissimosminima , well this line is written by author to introduce the contradiction in the further line, because as per author it seems that IGCC provided us the solution, but they didnt take two grave environmental dangers into consideration, so overall If we look we are basically discussing that even though IGCC is providing us some solution but it can still cause environmental problems.

Hi suranamohit2694 can you please let me know, what is the answer according to you, so that I can help you, because Para 2,3,and,4 are perfectly in line with option B. In para 1 author introduced igcc then in para 2 he discussed that two dangers are ignored and Para 3 and 4 are elaborating those 2 dangers even though they are helping in some case.
