Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
This question tests your understanding of sentence function and text organization. The phrase 'Contrary to the prevailing theory, which posits gradual evolutionary change' is introductory/contrasting. A comma closes it before the main clause 'the fossil evidence suggests.' Each sentence in a well-constructed text serves a specific purpose. Consider what role this sentence plays in the argument: does it introduce, support, contrast, or conclude an idea? Understanding why an author includes specific sentences helps you grasp the overall argument. Each sentence should serve a clear purpose: introducing ideas, providing evidence, acknowledging counterarguments, or drawing conclusions. Identify the role to understand the structure.
Key Evidence:
• "Contrary to the prevailing theory, which posits"
• "the fossil evidence suggests"
Why others are wrong: A (A colon doesn't fit for transitioning from introductory phrase.), C (Missing punctuation fails to transition properly to main clause.), D (A semicolon is too strong; the first part isn't an independent clause.).
