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.

Correct — A. Sentence 2 points back to nothing and states the goal: 'To mitigate the worst effects of climate change, the global community must drastically reduce its reliance on carbon-intensive energy production.'

1 gives the means: 'A key strategy is to diversify energy sources'.
3 refers back to 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 has to come first.
• (c)
  4, 1, 2, 3 — Opens with Additionally, which adds to a point already made. With nothing before it, sentence 4 cannot begin the paragraph.
• (d)
  2, 3, 1, 4 — Puts This shift straight after sentence 2, so the shift's benefits arrive before sentence 1 names the shift: transitioning from fossil fuels to renewable alternatives.

Solve in two passes. First the opener, the sentence that points back to nothing. Sentence 1's strategy needs a goal, 3's This shift needs a shift, and 4 opens with a connector, so 2 opens.

Then the links. The strategy answers the goal, This shift picks up the transitioning in sentence 1, and Additionally brings in a second measure.

Key facts

• A connector such as Additionally, Moreover or Furthermore adds to an earlier point, so it cannot open a paragraph.
• Phrases such as This shift or This process need the thing they name to come earlier.
• Here the paragraph runs goal (2), strategy (1), its effects (3), a second measure (4).

Common traps

• Opening with sentence 1 because it names the strategy — A key strategy needs the goal in sentence 2.
• Placing 3 right after 2 — This shift refers to the transition described in sentence 1.
