Explanation
PASSAGE
The ancient civilization developed advanced irrigation systems, built monumental temples, and _______ extensive trade networks throughout the region.
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. Parallel structure requires matching verb forms: 'developed,' 'built,' and 'established' are all past tense verbs. 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:
• "developed advanced irrigation systems, built monumental temples, and"
Why others are wrong: D ('To establish' is an infinitive; other verbs are past tense.), C ('Establishes' is present tense; other verbs are past tense.), A ('Establishing' breaks parallel structure with 'developed' and 'built.').
