Parajumbles Question 8 - CAT 2021
Question
- A popular response is the exhortation to plant more trees.
- It seems all but certain that global warming will go well above two degrees—quite how high no one knows yet.
- Burning them releases it, which is why the scale of forest fires in the Amazon basin last year garnered headlines.
- This is because trees sequester carbon by absorbing carbon dioxide.
Step-by-Step Explanation
- Correct Sequence: 2143
- Explanation: Sentence 2 establishes the opening premise: global warming is on track to surge past two degrees. Sentence 1 introduces a popular environmental mitigation campaign to fight this trend ("A popular response is the exhortation to plant more trees"). Sentence 4 provides the underlying scientific justification for that movement via a causal indicator ("This is because trees sequester carbon..."). Sentence 3 tracks the dangerous flip side of this equation: since trees store carbon, burning them down (like the Amazon fires) releases that carbon straight back into the atmosphere.
- FundaMakers Tip: Locating Causal Anchors. A sentence starting with a phrase like "This is because..." (Sentence 4) serves as an explanation. It must sit immediately behind the specific human action or strategy that requires explaining (planting more trees in Sentence 1), forming a tight 1-4 block.
