Problem 13 - Entrance Test

The Amazon rainforest plays a crucial role in global climate regulation. [1] Efforts to combat this destruction include international conservation agreements and sustainable land-use initiatives. [2] It absorbs vast amounts of carbon dioxide, acting as a vital carbon sink. [3] However, the sheer scale of the forest and economic pressures make enforcement challenging. [4] Deforestation, driven by agriculture and logging, threatens this delicate balance. [5] To improve the flow and logic of the paragraph, where should sentence [5] ('Deforestation, driven by agriculture and logging, threatens this delicate balance.') be placed?

Correct: C

The paragraph should logically move from establishing the Amazon's importance to introducing the threat, then discussing solutions and challenges. Sentences [1] and [3] describe the Amazon's crucial role and its function as a carbon sink. Sentence [5] introduces the threat (deforestation). Therefore, placing sentence [5] immediately after sentence [3] creates a clear flow: role -> threat. Sentences [2] and [4] then discuss efforts and challenges related to addressing this threat.
