Answer

Brief Explanations:

For Part A, we need to analyze the function of paragraph 3 in the article's structure. Option A is incorrect as the paragraph doesn't focus on why sedimentary rocks are most common. Option B is wrong since there's no contrast with igneous rocks. Option D is incorrect as chemical - composition comparison isn't the main point. Option C is correct as it describes sedimentary - rock formation. For Part B, the sentence that supports the idea of describing the formation process is "Sedimentary rocks are formed at the surface of the Earth, either in water or on land."

Answer:

Part A: C. It describes the process by which sedimentary rocks are formed. Part B: A. "Sedimentary rocks are formed at the surface of the Earth, either in water or on land."
