Set 1: Form, Structure & Sense (Advanced)
Explanation
PASSAGE
The research suggests that early intervention programs, when properly _______ can significantly improve developmental outcomes for children at risk.
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 'when properly implemented' is a reduced adverbial clause that is parenthetical. A comma closes this phrase before the main verb 'can significantly improve.' 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:
• "intervention programs, when properly"
• "can significantly improve"
Why others are wrong: A (A colon doesn't fit for closing an adverbial clause.), B (A semicolon is too strong for closing an adverbial clause.), C (Missing punctuation fails to close the parenthetical phrase.).
