Key idea: This is a Science + Culture synthesis summary question, recognisable because it takes a scientific term (Anthropocene) and analyzes its broader cultural and political implications.
Step 1: Map the argument. Premise: Geologists propose the Anthropocene to mark human dominance over the environment. Counter-claim: Critics argue it is a cultural narrative, not a neutral classification. Mechanism: It frames humanity as a monolithic force. Consequence: This obscures inequalities and risks absolving specific corporate/political structures by blaming 'humanity' as a whole.
Step 2: Identify the core thesis. The author's main point aligns with the critics: the term is a problematic cultural narrative that hides systemic inequalities by blaming a monolithic 'humanity'.
Step 3: Evaluate Option A. Claims it is a "neutral scientific classification" that helps hold structures accountable. This directly contradicts the passage, which says it is "not merely neutral" and "absolves" specific structures.
Step 4: Evaluate Option B. Captures the core thesis perfectly: it is a cultural narrative, it blames a monolithic force, it obscures inequalities, and it risks absolving specific drivers.
Step 5: Evaluate Option C. Claims its primary value is fostering a "unified cultural identity" to "equally share responsibility." The passage frames this unified identity as a negative risk ("fatalistic cultural identity") that obscures inequality, not a positive value.
Step 6: Evaluate Option D. Claims geologists and critics "agree." The passage presents them in opposition ("Yet, critics argue...").
Answer: Option B
