To meet its domestic petroleum demand,
the country of Thessia intends to construct two new off-shore refineries in the oil-rich region off its southern coast. Although this project is an enormous one, in all probability, it is not big enough to realize its intended goal. It is true that
adding the projected output of the new refineries to the output that Thessia can achieve now would be enough to meet the current petroleum consumption. It will, however, take at least 10 years to complete the project, and by that point, approximately half of Thessia’s currently active oil fields will be depleted.
In the argument given, the two portions in boldface play which of the following roles?
(A) The first introduces a proposed plan that the argument provides support for; the second provides evidence in support of that plan.
(B) The first introduces a proposed plan that the argument provides support for; the second provides a reason for not adopting a possible alternative plan .
(C) The first introduces a course of action that is evaluated by the argument; the second provides evidence used to support that course of action against possible alternatives.
(D) The first introduces a proposed course of action for realizing a certain goal; the second provides evidence used to support the evaluation of that course of action, made by the argument.
(E) The first introduces a proposed course of action for achieving a certain goal; the second is a claim that has been used to support this course of action but that the argument insists is inaccurate.

Experts' Global Official ExplanationStrategy: Determining the main conclusion of the argument and finding the relation of the boldfaced portions with this conclusion
Logic: The argument evaluates a country’s plan, stated in the first boldface, to build new refineries to meet petroleum consumption; while doing so, the argument acknowledges, in the second boldface, that the output of the new and the old refineries together is sufficient to meet current demand but subsequently mentions that the old refineries will not function by the time the new refineries are completed. Overall, the main conclusion is that the plan is not likely to achieve its goal; in the context of the main conclusion – the first boldface is a plan that the argument seeks to evaluate; the second boldface is a consideration that the argument, as a whole, judges as an inadequate merit in the plan.
Main conclusion: The plan to build new refineries to meet petroleum consumption is not likely to achieve its goal.
Broad expectation from the correct answer choice: The first boldface is a plan/course of action/proposal that the argument seeks to evaluate/assess/weigh.
The second boldface is a consideration/fact that the argument judges as an inadequate merit in the plan/course of action/proposal.
A.
Merit(s):The first boldface presents a proposal; therefore, it is correct to state that the first boldface is “a plan”.
The second boldface presents a concrete/factual merit in the plan; therefore, it is correct to state that the second boldface “gives evidence”.
The second boldface presents a merit in the plan and thus supports the plan; therefore, it is correct to state that the second boldface “provides evidence in support” of the plan.
Demerit(s):The first boldface presents a plan and the main conclusion is that the plan is not likely to achieve its goal; so, the argument, as a whole, does not support the first boldface; therefore, it is incorrect to state that “the argument provides support” to the first boldface.
Because this answer choice does not correctly highlight the roles played by the two portions in boldface, this answer choice is incorrect.
B.
Merit(s):The first boldface presents a proposal; therefore, it is correct to state that the first boldface is “a plan”.
The second boldface presents a merit in the plan and thus supports the plan; so, it is correct to state that the second boldface is a “reason”.
Demerit(s):The first boldface presents a plan and the main conclusion is that the plan is not likely to achieve its goal; so, the argument, as a whole, does not support the first boldface; therefore, it is incorrect to state that “the argument provides support” to the first boldface.
The argument makes no mention of possible alternatives to the plan; therefore, it is incorrect to state that the second boldface “provides a reason for not adopting a possible alternative plan”.
Because this answer choice does not correctly highlight the roles played by the two portions in boldface, this answer choice is incorrect.
C.
Merit(s):The first boldface presents a proposal to build new refineries; therefore, it is correct to state that the first boldface is “a course of action”.
The first boldface presents a plan and the argument assesses the plan to conclude that the plan is not likely to achieve its goal; therefore, it is correct to state that the course of action presented in the first boldface is “evaluated by the argument”.
The second boldface presents a concrete/factual merit in the plan and thus supports the plan; therefore, it is correct to state that the second boldface “provides evidence”.
Demerit(s):The second boldface presents a merit in the plan and thus supports the plan; however, the argument makes no mention of possible alternatives to the plan; therefore, it is incorrect to state that the second boldface “supports the course of action against possible alternatives”.
Because this answer choice does not correctly highlight the roles played by the two portions in boldface, this answer choice is incorrect.
D.
Merit(s):The first boldface presents a proposal to build new refineries; therefore, it is correct to state that the first boldface is “a proposed course of action”.
The first boldface presents the country’s plan to build new refineries to meet the country’s domestic petroleum demand; therefore, it is correct to state that the first boldface “introduces a proposed course of action for realizing a certain goal”.
The second boldface presents a concrete/factual merit in the plan and thus supports the plan; therefore, it is correct to state that the second boldface “provides evidence”.
The second boldface presents a merit in the plan that the argument uses to assess the plan and establish the conclusion that the plan is not likely to achieve its goal; therefore, it is correct to state that the second boldface “supports the argument's evaluation of that course of action”.
Demerit(s):None
Because this answer choice correctly highlights the roles played by the two portions in boldface, this answer choice is correct.E. Trap.
Merit(s):The first boldface presents a proposal to build new refineries; therefore, it is correct to state that the first boldface is “a proposed course of action”.
The first boldface presents the country’s plan to build new refineries to meet the country’s domestic petroleum demand; therefore, it is correct to state that the first boldface “introduces a proposed course of action for achieving a certain goal”.
The second boldface states that the output of the new and the old refineries together is sufficient to meet current demand, thus making an assertion; therefore, it is correct to state that the second boldface is a “claim”.
The second boldface presents a merit in the plan; therefore, it is correct to state that the second boldface “supports the course of action”.
Demerit(s):The argument considers the merit highlighted in the second boldface “inadequate” and passes no judgment on the “accuracy” of the merit; therefore, it is incorrect to state that the argument regards the second boldface as “inaccurate”.
Because this answer choice does not correctly highlight the roles played by the two portions in boldface, this answer choice is incorrect.
An interesting discussion: A student once wrote to us asking how the term “support” can be used for the second boldface when the argument concludes that the course of action is not likely to achieve its goal? Can you find the gap in the student’s reasoning? Please note that the correct answer choice states that the second boldface “supports the evaluation of the course of action” and not “supports the course of action”; the argument considers the second boldface while assessing the course of action and is thus “helpful in” evaluating the course of action; in the context of the term “support” as used in answer choice D, whether the argument supports the course of action, meaning whether the argument evaluates the course of action as likely to succeed, is irrelevant.
D is the best answer choice.
