Set 14: Boundaries (Advanced)
Explanation
PASSAGE
Each of the students _______ required to submit a research paper by Friday.
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. 'Each' is always singular, regardless of what follows in the prepositional phrase. Use singular 'is.' 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:
• "Each (singular)"
• "of the students (prepositional phrase)"
Why others are wrong: D ('Were' is plural.), C ('Are' is plural; 'each' is always singular.), A ('Have been' is plural.).
