Explanation
PASSAGE
The professor explained the theory _______ she asked students to apply it to real-world scenarios.
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 boundaries and punctuation. Two independent clauses with conjunctive adverb 'then' require a semicolon. To determine the correct answer, examine where complete thoughts begin and end. Look for independent clauses that need proper separation. A period, semicolon, or appropriate conjunction can correctly join or separate these ideas. When analyzing sentence boundaries, pay attention to how ideas flow from one sentence to the next. Correct punctuation ensures clarity and prevents confusion for readers. Review the options carefully to identify which choice creates proper sentence structure.
Key Evidence:
• "two independent clauses"
• "then (conjunctive adverb)"
Why others are wrong: A (Missing punctuation creates run-on sentence.), B (Colon is incorrect; 'then' doesn't introduce a list or explanation.), D (Comma creates comma splice with independent clauses.).
