Set 8: Boundaries
Explanation
PASSAGE
The documentary examined three historical _______ the Industrial Revolution, the Civil Rights Movement, and the Space Race.
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. Colon introduces the list of three periods. 'The documentary examined three historical periods' is a complete clause. 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:
• "complete clause"
• "list follows"
Why others are wrong: C (Semicolon joins clauses, not introduces lists.), D (Punctuation needed before the list.), A (Comma is weaker than colon for formal list introduction.).
