question to the right.
which choice below best paraphrases the sentence?
earths climate has an inherent variability that makes it difficult to determine the human impact on it.
earths climate has an inherent variability that makes it difficult to determine the human impact on it.
the climate of earth is inherently variable, so its hard to determine the impact of humans.
because earths climate changes naturally, it is hard to know how human activity affects it.
peoples activities greatly affect earths climate.

Explanation:

• The original sentence emphasizes Earth's climate variability and its impact on determining human influence.
• The second option "The climate of Earth is inherently variable, so it's hard to determine the impact of humans" is a direct paraphrase.
• The third option adds "changes naturally" which is an inference (though valid) but not a strict paraphrase.
• The first option is almost the same as the original (not a good paraphrase).
• The fourth option changes the meaning (focuses on human impact rather than difficulty in determining it).

Answer:

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