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.
1. 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.
[Reveal] Spoiler:
B


2. The passage above most likely appeared first in

(a) The national section of a syndicated newspaper.
(b) A journal devoted to new technologies.
(c) A personal weblog.
(d) A newsletter published by an environmental group.
(e) A newsletter published by a coal plant.
[Reveal] Spoiler:
D


3. The author most likely uses the word "seems" in this line in order to

(a) Draw attention to an obvious solution.
(b) Highlight the need for agreement among environmental and industrial groups.
(c) Suggest that an apparent solution can not be trusted.
(d) Make it clear that environmental experts must have the final say in the matter.
(e) Avoid overstating the case for IGCC coal plants.
[Reveal] Spoiler:
C


4. It can be inferred that the author details the workings of IGCC power plants in paragraph 1 primarily in order to

(a) Explain a more efficient coal-burning process, in order to create consensus among environmental and industrial groups.
(b) Form a bridge between the first and fourth paragraphs, which both discuss the containment of carbon dioxide emissions.
(c) Suggest that coal-burning power plants could be even more efficient if they integrated three thermodynamic cycles instead of two.
(d) Demonstrate the availability of new technologies that can be put in the service of environmental responsibility.
(e) Acknowledge the reasons for viewing IGCC plants as a solution, before demonstrating that the environmental problems of coal-burning plants outweigh the solution of burning coal more efficiently.

[Reveal] Spoiler: Question V02-38 explanation
This question requires a look at the passage as a whole in order to determine the author's purpose in writing. The first paragraph introduces the idea that IGCC coal plants are more energy efficient than traditional coal plants and explains how the process works. The word however, though, signals that the author of the passage is changing the direction of the argument. Paragraphs 3 and 4 discuss the grave environmental dangers of IGCC plants, making it clear that the author's main concern is pointing out potential problems.
  1. The passage does not discuss the popularity of coal-burning power plants.
  2. The passage begins with an explanation of what seems a possible environmental solution, then argues that what seems to be a solution may actually cause different kinds of problems.
  3. The first paragraph does explain the thermodynamic cycles of IGCC plants, but the explanation is not the focus of the passage as a whole.
  4. The passage assumes the need for methods of reducing carbon emissions, but does not take up the argument directly.
  5. The passage does not discuss the cost, or economic feasibility, of constructing more coal-burning power plants.
[Reveal] Spoiler: Question V02-39 explanation
The question's use of the words most likely means that the answer depends on making an inference. Because the question does not reference a specific line or paragraph, the inference must be drawn from the passage as a whole. Phrases such as painfully expensive environmentally, in their quest for coal, and ill-considered current trend indicate that the author's sympathies lie with the environment.
  1. Though the passage references the United States, its clear environmental bias makes it inappropriate for the news section of a syndicated newspaper.
  2. The first paragraph explains IGCC technology, but the argument in the third and fourth paragraphs veers from the merely scientific.
  3. Though it is possible the article appeared on a personal weblog, its journalistic tone means it is more likely it appeared in a publication of a group.
  4. The argumentative tone in the second half of the passage makes this passage most likely to have been published in a newsletter explicitly concerned with environmental issues.
  5. The passage actually questions the environmental soundness of coal-burning plants.
[Reveal] Spoiler: Question V02-40 explanation
To answer this question, look at the phrase seems in the context of the passage. The phrase occurs at the beginning of the second paragraph and signals a transition between the introduction and main argument of the passage. The first paragraph discusses the apparent efficiency of IGCC plants, but the third and fourth discuss the two grave environmental dangers the author believes coal-burning plants present.
  1. The passage is questioning the soundness of IGCC plants as a solution.
  2. The passage does not focus on agreement among environmental and industrial groups.
  3. Since IGCC plants burn coal more efficiently, the passage suggests, they seem like a good solution to an environmental problem. The third and fourth paragraphs, however, argue that the plants will perpetuate other problems.
  4. The passage does not discuss environmental experts.
  5. The passage ultimately does not build a case at all for IGCC plants.
[Reveal] Spoiler: Question V02-41 explanation
To answer this question, consider the role of the first paragraph in the passage as a whole. The first paragraph is the background to the argument constructed in paragraphs 2 and 3 that IGCC plants do not account for other environmental dangers. The word seems in the last sentence of paragraph 1 signals that the author believes the IGCC solution would be reasonable if not for other environmental factors.
  1. The passage explains the process, but does is not specifically aimed at creating consensus.
  2. Both paragraphs discuss carbon dioxide emissions, but for opposite purposes.
  3. This is not discussed in the passage.
  4. The passage does not directly address the availability of IGCC technology.
  5. The phrase making moderate strides indicates the author's belief that IGCC plants are an improvement over traditional plants. The third and fourth paragraphs, however, state clearly that the author does not consider the moderate improvement to be adequate.

Hi Bunuel,

In Q3 option E, can you please explain more on "The passage ultimately does not build a case at all for IGCC plants."? What is the meaning of "building a case"?

Can someone please explain Q2. I am non-native english speaker and having hard time to understand it.

"A" says syndicate Newspaper. When I search for Syndicate in Google, I found "a group of individuals or organizations combined to promote a common interest.".
Why can't be have A as an option? A group of individuals who are inclined towards Environment and who also runs a newpaper related to Environment issues.

In Explanation of C Bunuel said "Though it is possible the article appeared on a personal weblog, its journalistic tone means it is more likely it appeared in a publication of a group.". What's the Journalist tone? How is it different from tone of Weblog?

In Question 1 B, we have "Argue that coal-burning power plants may cause more environmental problems than they solve.". Nowhere in the passage Author discussed about the problems solved by coal-burning power plans (new is not mentioned).

Sorry I am completely lost in this passage so multiple posts.

Very poor quality Q1, as coal burning plant itself is irrelevant to the passage. It was IGCC being the focus of the discussion.

Hi,

This answer is actually very hypothetical.
as i understand the journal write more in details with data (no. of plants, tonnes of CO2 emission, etc etc.), the references, name of scientists, name of the research institute etc.

i think the answer cannot be D

regards

Sushil Kumar

Completely agree, the focus in the passage on the cleaning technology and not on the power plants themselves. Could someone please explain?
