Responses

Earth’s climate has an inherent variability that makes it difficult to determine the human impact on it.
Earth’s climate has an inherent variability that makes it difficult to determine the human impact on it.

The climate of Earth is inherently variable, so it’s hard to determine the impact of humans.
The climate of Earth is inherently variable, so it’s hard to determine the impact of humans.

Because Earth’s climate changes naturally, it is hard to know how human activity affects it.
Because Earth’s climate changes naturally, it is hard to know how human activity affects it.

People’s activities greatly affect Earth’s climate.

Answer 1

The sentence paraphrased as 'Because Earth's climate changes naturally, it is hard to know how human activity affects it' best retains the original meaning by emphasizing the challenge in distinguishing human influence on the climate due to its natural variability. Therefore correct option is C

Step-by-step explanation:

The best paraphrase of the sentence 'Earth's climate has an inherent variability that makes it difficult to determine the human impact on it' is 'Because Earth's climate changes naturally, it is hard to know how human activity affects it.' This paraphrase maintains the original meaning of the sentence by emphasizing the natural variability of the climate and the subsequent challenges this presents in discerning the effects of human influence.

Research supports that while the climate changes naturally, there is a significant amount of evidence indicating that human activity, particularly since the industrial revolution, has had a profound and rapid impact on the climate, thereby intensifying the greenhouse effect.

Understanding the difference between natural climatic changes and those influenced by humans is crucial in the context of global climate change, as it helps to inform potential mitigation and adaptation strategies in the face of evolving climate science.
