Rearrange the following sentences to form a coherent paragraph:
1. These factors include the amount of sunlight received, the composition of the atmosphere, and the Earth's orbit.
2. The long-term variations in Earth's climate are influenced by a complex interplay of natural and anthropogenic factors.
3. The most significant anthropogenic factor is the emission of greenhouse gases from industrial activities.
4. Together, these elements determine the planet's overall energy balance and, consequently, its average temperature.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2, 1, 4, 3.
Logical flow:
2: This is the introductory sentence. It presents the main subject—Earth's climate—and mentions that it is influenced by both 'natural and anthropogenic factors.'
1: This sentence begins with 'These factors,' which refers directly back to the 'natural and anthropogenic factors' mentioned in sentence 2. It lists specific examples like sunlight, atmosphere, and orbit.
4: This sentence explains the result of the elements listed in sentence 1. The phrase 'Together, these elements' acts as a link to show how they collectively determine the 'energy balance' and 'temperature.'
3: This sentence narrows the focus to the 'most significant anthropogenic factor' (greenhouse gases). It provides a specific, detailed conclusion to the general discussion started in sentence 2.
Final Passage: The long-term variations in Earth's climate are influenced by a complex interplay of natural and anthropogenic factors. These factors include the amount of sunlight received, the composition of the atmosphere, and the Earth's orbit. Together, these elements determine the planet's overall energy balance and, consequently, its average temperature. The most significant anthropogenic factor is the emission of greenhouse gases from industrial activities.
Hence, the chosen option is correct.
