Set 8: Boundaries
Explanation
PASSAGE
The author's argument rests on two key _______ historical precedent and statistical evidence.
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 two premises. 'The author's argument rests on two key premises' 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: A (Punctuation needed before the list.), D (Comma is weaker than colon for formal list introduction.), B (Semicolon joins clauses, not introduces lists.).
