Concept:Match phrases from Column 1 and Column 2 to form grammatically correct and contextually logical sentences.
Explanation:Phrase A talks about rapid action to reduce emissions and logically pairs with F ("the curve of species at risk") because the action flattens that curve.
Thus, A-F is a correct pair.
Phrase B discusses the Amazon basin and early cultivation; it matches D, which mentions inhabitants eating squash and cassava long ago.
So B-D is a correct pair.
Phrase C defines phytoliths as plant microfossils; it pairs with E because phytoliths can identify past plants.
Thus, C-E is a correct pair.
Among the given options, only Option B lists a single correct pair (A-F).
Option A lists B-D (correct) and C-F (incorrect); Option C lists C-D (incorrect); Option D lists A-E (incorrect).
Therefore, only Option B is fully correct.
Answer:Option B
