Rearrange the following sentences to form a coherent paragraph: 1. A key strategy is to diversify energy sources, transitioning from fossil fuels to renewable alternatives like solar, wind, and geothermal power. 2. To mitigate the worst effects of climate change, the global community must drastically reduce its reliance on carbon-intensive energy production. 3. This shift not only decreases greenhouse gas emissions but also improves air quality and creates new economic opportunities. 4. Additionally, policies that promote energy efficiency in buildings and transportation can further lower overall energy consumption.

- (b)1, 2, 3, 4
- (c)4, 1, 2, 3
- (d)2, 3, 1, 4
Answer
Why
Correct — A. Sentence 2 opens: 'To mitigate the worst effects of climate change, the global community must drastically reduce its reliance on carbon-intensive energy production.' It points back to nothing.
1 gives the means: 'A key strategy is to diversify energy sources, transitioning from fossil fuels'.
3 names that move: 'This shift not only decreases greenhouse gas emissions'.
4 adds a second measure: 'Additionally, policies that promote energy efficiency' → 2, 1, 3, 4, option (a).
Why the others are wrong
- (b)1, 2, 3, 4 — Opens with A key strategy, a strategy for a goal not yet stated. The goal, cutting reliance on carbon-intensive energy, is sentence 2, which must come first.
- (c)4, 1, 2, 3 — Opens with Additionally, which adds to a point already made. Nothing precedes it, so sentence 4 cannot begin the paragraph.
- (d)2, 3, 1, 4 — Puts 3 straight after 2, so This shift comes before sentence 1 describes it, "transitioning from fossil fuels to renewable alternatives". The effects arrive before their cause.
Concept
Solve a jumble in two passes. First find the opener: the sentence that stands without pointing back. Sentence 1 needs a goal for its strategy, 3 needs a shift to refer to, and 4 opens with a connector, so 2 opens.
Then chain by links. A key strategy answers the goal, the shift in sentence 3 is the transition in 1, and Additionally adds a second measure after the first.
Key facts
- A sentence that opens with a reference phrase such as This shift or This process needs the sentence it refers to placed before it.
- Additionally adds a point to one already made, so a sentence opening with it cannot open the paragraph.
- Here the paragraph runs goal (2), first measure (1), its effects (3), second measure (4).

Common traps
- Opening with sentence 1 because it names the strategy — A key strategy needs the goal from sentence 2 first.
- Placing 3 right after 2 — This shift needs the transition from fossil fuels described in sentence 1.
