Set 13: Boundaries
Explanation
PASSAGE
The medicine _______ side effects can include drowsiness and dizziness, should be taken with food.
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. 'Whose side effects can include drowsiness and dizziness' is a nonessential clause (extra info about the medicine). Use comma before 'whose' and note the closing comma after 'dizziness.' 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:
• "nonessential clause"
• "whose (possessive)"
Why others are wrong: C (Semicolon would create a fragment.), B (Missing comma to set off nonessential clause.), D ('Who's' means 'who is'—wrong form. Need possessive 'whose.').
