Passage A
Proponents of formalizing the Anthropocene as a new geological epoch argue that human activity has left an indelible, globally synchronous mark in the stratigraphic record. They point to the mid-twentieth century—characterized by the 'Great Acceleration' of industrialization, thermonuclear testing, and synthetic chemical proliferation—as the definitive boundary line. By identifying a specific 'golden spike' (a Global Boundary Stratotype Section and Point) in lake sediments containing radioactive isotopes and microplastics, these stratigraphers seek to establish a rigid chronological marker. For them, the Anthropocene is a precise geological unit, defined by the same rigorous physical metrics used to demarcate the Cambrian or the Holocene. Establishing this boundary is not merely symbolic; it provides a standardized framework for measuring the catastrophic scale of anthropogenic changes against Earth's deep history.

Passage B
To restrict the Anthropocene to a mid-twentieth-century start date is to fundamentally misunderstand the nature of human influence on our planet. Anthropologists and archeologists argue that human modification of the Earth is a cumulative, diachronic process spanning millennia. The onset of agricultural practices ten thousand years ago, followed by widespread deforestation and megacity construction, initiated planetary alterations that cannot be neatly pinned to a single radioactive stratum. Treating the Anthropocene as a formal stratigraphic epoch with a post-1950 'golden spike' reduces a complex, ongoing socio-ecological phenomenon to an arbitrary line in the mud. Instead, the Anthropocene should be conceptualized as an ongoing geological 'event'—a continuous transformation similar to the Great Oxidation Event, which unfolded over millions of years. This framing shifts the focus from establishing precise chronological boundaries to understanding the unfolding dynamics of human agency over deep time.

Based on both passages, which of the following statements best describes the functional relationship between Passage B and Passage A?

  1. A
    Passage B challenges the core premise of Passage A by suggesting that human-induced environmental change is an unmeasurable phenomenon that has not left a physical footprint on Earth.
  2. B
    Passage B supports the timeline proposed in Passage A but suggests that agricultural sediment layers are superior to radioactive isotopes for establishing a precise mid-twentieth-century marker.
  3. Passage B reframes the concept introduced in Passage A, arguing that defining the Anthropocene as a localized stratigraphic epoch oversimplifies a protracted, multi-millennial ecological process.Cevap
  4. D
    Passage B elaborates on the geological metrics detailed in Passage A, explaining how radioactive fallout from the mid-twentieth century integrates with ancient agricultural deposits.

Cevap

Passage B reframes the concept introduced in Passage A, arguing that defining the Anthropocene as a localized stratigraphic epoch oversimplifies a protracted, multi-millennial ecological process.
The correct option is correct because Passage B does not reject the underlying reality of human impact on the planet, but rather reframes how we should conceptualize it. While Passage A describes the Anthropocene as a formal, mid-twentieth-century stratigraphic epoch established by a rigid chronological marker, Passage B argues that this boundary-focused view is too narrow. Passage B contends that human influence is a diachronic, cumulative process spanning thousands of years (beginning with agriculture) and should instead be viewed as an ongoing geological event.

Adım Adım Çözüm

1
Identify the central argument of Passage A.
Passage A advocates for formalizing the Anthropocene as a precise geological epoch beginning in the mid-twentieth century, defined by specific stratigraphic markers (a 'golden spike').
This establishes the baseline perspective that the second passage responds to.
2
Analyze Passage B's counterargument and conceptual framework.
Passage B rejects the mid-twentieth-century start date and the stratigraphic 'golden spike' approach, arguing instead that human influence is a cumulative process spanning millennia that should be treated as an ongoing geological 'event' rather than an epoch.
This defines the point of divergence between the two authors.
3
Evaluate the options to find the statement that accurately captures this relationship.
The option stating that Passage B reframes the concept in Passage A by arguing that a stratigraphic epoch oversimplifies a multi-millennial process aligns perfectly with the textual evidence.
This select option accurately synthesizes the relationship without introducing unsupported claims or distortions.
