Official Solution:


To address the issue of declining marine biodiversity, [b]a group of environmental scientists proposes the creation of large offshore marine reserves. They argue that these reserves would significantly reduce human impact on marine ecosystems. However, the proposal might not be as effective as anticipated. It is acknowledged that establishing these marine reserves would likely lead to a reduction in local fishing efforts, potentially benefiting marine life. Yet, the time required to establish and enforce these reserves could allow for continued degradation of marine habitats, undermining the long-term benefits of the reserves.

In the argument given, the two bolded portions play which of the following roles?[/b]


A. The first introduces a proposed course of action that the argument critiques; the second gives evidence in support of that course of action.
B. The first introduces a proposed solution to an environmental problem; the second provides a reason supporting this solution, though the argument questions its overall effectiveness.
C. The first presents a strategy for marine conservation; the second is a claim regarding the potential benefits of this strategy, which the argument suggests may be insufficient.
D. The first outlines an environmental initiative; the second is a statement used to endorse the initiative but which the argument finds to be potentially flawed.
E. The first details a plan for improving marine biodiversity; the second offers evidence supporting the plan, yet the argument expresses concerns about the plan's long-term viability.


C) The first presents a strategy for marine conservation; the second is a claim regarding the potential benefits of this strategy, which the argument suggests may be insufficient.

• This choice accurately describes the roles of the two boldfaced portions. The first boldface portion introduces the strategy of creating offshore marine reserves, while the second boldface portion discusses a potential benefit of this strategy (reduction in local fishing efforts). However, the overall argument questions the sufficiency and timeliness of this strategy in achieving its intended goal, which aligns with the role described in option C.

The other options do not as accurately describe the roles of the boldfaced portions in the context of the argument: A) This is not accurate because the second boldface portion does not provide evidence in support of the course of action; rather, it presents a potential benefit that is still questioned by the argument.

B) This option is close, but it does not capture the argument's emphasis on questioning the overall effectiveness of the proposed solution.

D) This choice inaccurately suggests that the second statement is used to endorse the initiative. The argument acknowledges the potential benefit but questions its effectiveness.

E) Similar to B, this option does not fully capture the argument's critical stance on the long-term viability and sufficiency of the plan.

Therefore, (C) is the correct answer, as it best represents the logical roles of the two boldfaced portions within the argument's structure.


Answer: C
­E states that in the long term it is not viable, (this part does talk about timliness of the strategy)

Then bunnel, How do you eliminate E?
­
Thank you for the question! 

Sorry it took me a bit to get back with you. The way to elimite E would be to see the role of the second statement. Here, (E) says Evidence and the seconed boldeded statement is not evidence. 
I will improve the explanation - I think it was too generic to be helpful.

­C best reflects the structure of the argument:

The first part presents a strategy for marine conservation: This refers to the introduction of creating large offshore marine reserves.

The second is a claim regarding the potential benefits of this strategy, which the argument suggests may be insufficient: This captures how the passage acknowledges a potential benefit (reduced fishing effort) but raises a concern about the time needed for establishment and enforcement potentially undermining the long-term effectiveness.
The other options, while partially capturing some aspects, miss the key point:

A & E: These both imply the second bolded part provides evidence for the strategy. However,  it doesn't function as pure evidence, but rather acknowledges a potential positive outcome within the context of the strategy.

B: This focuses on questioning effectiveness in general, whereas the argument is more nuanced, raising a specific concern about long-term viability.

D: ­This suggests the second portion is flawed, which isn't the focus; the issue is with timing of the strategy.

The reason E is wrong is that the argument doesn't talk about long-term viability.

It says the short-term costs (& time) of lack of enforcement may outweigh the long-term benefits which may accrue.

Long term viability means sustainability of the project in the long run.

Arent these two clearly different or why would they mean the same?

C says it may be ineffective, but the argument says it may be less effective than anticipated. Should the answer then not be B ? The argument does question effectiveness of the solution when it says it may not be as effective as anticipated

I agree there's too subtle of a difference to reject certain options. I felt the role of the second statement was a bit murky considering the options. In my opinion, this question could use a bit of rework, mainly to tighten the incorrect options so they’re clearly wrong rather than falling into a gray area.

bb - Let me know your thoughts.

I don’t quite agree with the solution. The Second boldface is not evidence - its a prediction, and an argument, which supports the plan. It contains no data, no examples of such projects - a simple prediction. Therefore, it is not evidence and C) is incorrect

I chose D instead of C, because C says that the second portion is evidence... It seems to me the second part is more of a prediction than evidence. Bunnel, could you clarify it, please?

Hi,
So, generally I approach BF questions in the following manner: I break down each sentence into its role and direction wrt conclusion.
What's the conclusion here? The plan to create marine reserves will not work out to address decline in biodiversity.
Supporting premises: (= same direction as the conclusion= doesnt support the plan)
i) reserves can take years to designate and police
ii) this will further allow habitats to deteriorate beyond recovery and nullify any benefit

Counter premises (= opposite direction of the conclusion = supports the plan):
i) These reserves will reduce human impact on marine ecosystems
ii) Reserves will cut local fishing pressure => boost marine popn

Let's break it down, and also take each BF1 one by one:
Prethinking: BF1 (plan proposed by env scientists)
BF2: support for this plan
For your doubt, lets focus on C) and D):
C) First part is correct, second part also seems correct.
D) BF1 is not really contextual background, its a plan proposed by the scientists (so not correct), BF2 also incorrect in the sense that it supports the plan not the context. Context would have been something that explains the problem - but doesn't talk about any actionable steps
>> Evidence is a reason, fact, or consideration that supports (in this case) a claim. BF2 does fall in this bucket.

Hope this helps!
