Set 15: Form, Structure & Sense (Intermediate)
Explanation
PASSAGE
The algorithm, designed to optimize energy distribution across the _______ has reduced power consumption by nearly thirty percent.
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 participial phrase 'designed to optimize energy distribution across the grid' is parenthetical. A comma closes this phrase before the main verb 'has reduced.' 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 algorithm, designed to optimize"
• "has reduced power consumption"
Why others are wrong: D (Missing punctuation fails to close the parenthetical phrase.), C (A semicolon is too strong for closing a participial phrase.), A (A colon doesn't fit for closing a participial phrase.).
