Explanation
PASSAGE
Recent studies show that the archaeological discovery provided evidence that ancient civilizations _______ complex trade networks spanning thousands of miles.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
[Variation 1] This question tests your understanding of sentence function and text organization. 'Had established' (past perfect) correctly indicates an action completed before another past event ('the discovery provided'). 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:
• "The archaeological discovery provided evidence that"
• "trade networks spanning thousands of miles"
Why others are wrong: A ('Have established' is present perfect; the context is entirely in the distant past.), B ('Establishing' is a participle; the clause needs a finite verb.), C ('Establishes' is present singular; subject is plural and context is past.).
