Set 13: Form, Structure & Sense (Intermediate)
Explanation
PASSAGE
The genome sequencing project, which has taken researchers more than a decade to _______ will provide invaluable insights into human evolutionary history.
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 relative clause 'which has taken researchers more than a decade to complete' is nonessential. A comma closes this clause before the main verb 'will provide.' 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 genome sequencing project, which has taken"
• "will provide invaluable insights"
Why others are wrong: D (A colon doesn't fit for closing a relative clause.), C (Missing punctuation fails to close the nonessential relative clause.), B (A semicolon is too strong for closing a relative clause.).
