Set 15: Boundaries (Intermediate)
Explanation
PASSAGE
The panel of experts—all of _______ recognized authorities in their respective fields—reviewed the proposed guidelines.
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. 'All' here takes a plural verb 'were.' 'Whom' is correct after preposition 'of.' 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:
• "all (plural)"
• "of whom (object after preposition)"
Why others are wrong: C ('Them' is incorrect; need relative pronoun 'whom.'), A ('Which' refers to things, not people.), D ('Who' should be 'whom' after preposition 'of.').
