Comprehension
Biodiversity is being lost at a rate not seen since the last mass extinction. But the United Nations decade-old plan to slow down and eventually stop the decline of species and ecosystems by 2020 has failed. Most of the plan's 20 targets - known as the Aichi Biodiversity Targeto have not been met. The Aichi targcto arc part of an international agreement called the UN Convention on Biological Diversity. and member states are now finalizing replacements for them. Currently referred to as the post-2020 Global Biodiversity Framework (GBF). its draft was published in July 2021. It aims to slow down the rate of biodiversity loss by 2030. And by 2050. biodiversity will be "valued. conserved. restored and wisely used. maintaining ecosystem services. sustaining a healthy planet and delivering benefits essential for all people". The GBF is a comprehensive plan. But success will require systemic change across public policy. That is both a strength and a weakness. If systemic change can be implemented, it will lead to real change. But if it cannot, there's no plan B. This has led some researchers to argue that one target or number should be prioritized and defined in a way that is clear to the public and to policy makers. It would be biodiversity's equivalent of the 2°C climate target.

This question asks which of the listed points is identified in the passage as a challenge specifically for implementing the post-2020 Global Biodiversity Framework (GBF), rather than as a description of the earlier Aichi Targets or of biodiversity loss in general.

  1. Option A: The unfulfillment of the pre-2020 targets is described in the passage as the outcome of the earlier Aichi plan, a fact about the past rather than a challenge facing the GBF's own implementation going forward. This is a description of prior failure, not a forward-looking implementation challenge.
  2. Option B: The passage explains that the GBF, being a comprehensive plan, depends on systemic change across public policy, and that this is risky because there is "no plan B" if such broad change does not occur. It goes on to say that some researchers therefore want one target defined "in a way that is clear to the public and to policy makers," implying that the framework's current lack of a single, clearly communicated target is precisely what could hinder its implementation. This directly identifies clarity of the action plan as a live concern for the GBF going forward.
  3. Option C: The threat of mass extinction is presented at the start of the passage as the broader context and motivation for having a biodiversity framework at all, not as a factor that makes implementing the GBF itself more difficult.
  4. Option D: Failure of the plan to save ecosystems describes the outcome attributed to the earlier Aichi Targets having not been met, again a statement about the past plan's results rather than an implementation challenge for the GBF.

Only the concern about the plan lacking a single, clearly defined target is framed by the passage as a forward-looking risk to the GBF's own success, making it the genuine implementation challenge among the options.

Therefore, the correct answer is clarity of action plan for the society and government.

This question asks why some researchers push for one biodiversity target to take priority over the many goals laid out in the post-2020 Global Biodiversity Framework (GBF). Let us weigh each option against the reasoning that runs through the discussion.

  1. Systemic policy change is difficult to implement: A framework loaded with many parallel targets asks governments to reform policy on several fronts at once, land use, agriculture, fisheries, finance, and more. When commitments are scattered like this, no single target carries enough political weight to force the kind of sweeping, coordinated policy shift that biodiversity protection actually needs. Concentrating attention on one target gives governments a clear, trackable benchmark, much like the 2 degrees Celsius goal did for climate action, and makes the difficult work of overhauling policy more achievable. This lines up with why researchers would favour prioritising a single target.
  2. Post-2020 Global Biodiversity Framework (GBF) is comprehensive: The GBF being comprehensive is precisely the problem researchers are responding to, not the reason they want one target prioritised. A framework's comprehensiveness explains why it is hard to implement, it does not explain the case for narrowing it down to a single priority.
  3. The 2 degrees Celsius climate target needs to be prioritized: The 2 degrees Celsius target belongs to climate policy, not biodiversity policy. It is invoked only as a reference point, an example of what a single unifying target can achieve, not as something that itself needs to be prioritised within the GBF.
  4. Biodiversity needs to be valued, conserved, restored and wisely used: This restates the broad aspirational aims found across the GBF's many goals. It describes what biodiversity policy should achieve overall, not the specific argument for why a single target should be prioritised over the rest.

Only the first option identifies the real obstacle, the difficulty of driving systemic policy change when effort is divided across numerous targets, which is exactly why some researchers want one target elevated above the others.

Therefore, the correct answer is Systemic policy change is difficult to implement.

The question asks which statement best captures the author's own opinion, rather than a fact or a claim made by others, about the post-2020 Global Biodiversity Framework (GBF). Here is each option assessed on its own merits.

  1. Implementation of the post-2020 GBF allows no middle ground for success or failure: This reflects a strong, evaluative judgment, the kind of decisive stance an author takes when arguing that a framework will either work fully or fail outright, with nothing achieved in between. This is the sort of pointed, opinionated claim an author makes to press home the stakes involved.
  2. It is high time countries re-evaluate the progress in achieving biodiversity targets: This is a plausible recommendation but reads as a general call to action rather than the author's core opinion about the framework's implementation itself. It is more of a procedural suggestion than a considered judgment.
  3. Biodiversity conservation should be prioritized over climate change at the global level: This sets up an either-or contest between biodiversity and climate priorities that is not actually being argued, the two are typically discussed as connected concerns, not competitors where one must be ranked above the other.
  4. The post-2020 GBF is the best way to prevent mass extinction: This is an overly absolute, sweeping claim. A measured discussion of a policy framework is usually careful not to declare any single framework as definitively "the best" solution to a problem as large as mass extinction, this overstates the tone of the argument.

The option that reads as the author's own considered judgment, rather than a hedge, a recommendation, or an overstatement, is the one about the framework leaving no middle ground for success or failure.

Therefore, the correct answer is Implementation of the post-2020 Global Biodiversity Framework (GBF) allows no middle ground for success or failure.

Approach Solution -2

This question is about identifying the central theme, the idea that ties the whole discussion together, rather than a detail mentioned in passing.

  1. The reason for failure of biodiversity conservation efforts at global level: Past shortcomings may be referenced to set up the discussion, but a piece built around the post-2020 GBF is fundamentally forward-looking, it is not primarily a post-mortem on why earlier efforts fell short.
  2. The inter-relationship between biodiversity conservation and climate change: The 2 degrees Celsius climate target is mentioned only as a point of comparison for how targets can be structured, this is a supporting detail, not the main subject.
  3. The future of biodiversity conservation efforts at global level: A discussion built around a newly adopted framework, the debate over prioritising targets, and its holistic design is, at its core, about what lies ahead for global biodiversity efforts, whether the new framework will succeed and how it should be structured going forward.
  4. The role of United Nations in biodiversity conservation at global level: No institutional focus on the UN's role is central here, the discussion centres on the substance of the framework's targets and their implementation, not on which body administers them.

The option that best captures the overall direction, forward-looking analysis of how global biodiversity conservation will proceed under the new framework, is the correct central theme.

Therefore, the correct answer is The future of biodiversity conservation efforts at global level.

Approach Solution -2

This is an inference question, the correct option is the one that follows logically from how the debate around the post-2020 GBF's design is framed, without being stated outright.

  1. The holistic nature of the post-2020 GBF is a boon: This treats the framework's comprehensiveness as purely positive. But the difficulty of implementing systemic policy change under a broad, multi-target structure is also part of the picture, so a purely positive reading is incomplete.
  2. The holistic nature of the post-2020 GBF is a bane: This treats it as purely negative. Yet a comprehensive framework also has the advantage of covering more ground and more dimensions of biodiversity loss than a narrow, single-target approach would, so a purely negative reading is equally incomplete.
  3. The holistic nature of the post-2020 GBF can be a boon or a bane: Taken together, the discussion cuts both ways, comprehensiveness broadens coverage, which helps, but it also dilutes focus and complicates systemic policy change, which hurts. The reasonable inference is that this same holistic design carries both possibilities depending on how it is implemented.
  4. The post-2020 GBF includes the 2 degrees Celsius climate target: The 2 degrees Celsius figure belongs to climate policy and is invoked only as an analogy for single-target design, the GBF itself does not incorporate it as one of its own targets.

Weighing both the benefits and the drawbacks of a broad, multi-target framework leads to the balanced inference that its holistic nature is capable of being either an advantage or a drawback.

Therefore, the correct answer is The holistic nature of the post-2020 Global Biodiversity Framework (GBF) can be a boon or a bane.
