Set 13: Form, Structure & Sense
Explanation
PASSAGE
The quantum computer, which processes information using _______ could potentially solve problems that would take classical computers billions of years.
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 processes information using qubits' is nonessential (set off by commas). It needs a closing comma before the main clause continues with 'could.' 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 quantum computer, which processes"
• "could potentially solve problems"
Why others are wrong: B (Missing punctuation fails to close the nonessential clause.), D (A colon doesn't fit for closing a relative clause.), C (A semicolon is too strong for closing a relative clause.).
