Set 10: Boundaries (Advanced)
Explanation
PASSAGE
The hypothesis _______ by the experimental results, was subsequently revised by the research team.
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. 'That was not supported by the experimental results' is an essential clause identifying which hypothesis. Use 'that' without comma. 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:
• "essential clause"
• "that (no comma)"
Why others are wrong: A ('That' shouldn't be preceded by a comma.), C ('Which' with comma makes it nonessential; but context suggests essential identification.), D ('Which' without comma is awkward; 'that' is preferred for essential clauses.).
