Final answer:
Without specific context for sentence 11, the best recommendation is to make no change, aligning with the guideline that essential information should not be separated by commas.
Step-by-step explanation:
The question asks which change needs to be made to sentence 11 in a given text. The instruction ‘Editing Focus: Commas with Nonessential and Essential Information’ applies directly to this question. When dealing with commas and essential information, it is important not to place commas around information that is vital to the understanding of a sentence. Given the lack of context for sentence 11, it’s difficult to ascertain whether the comma after “citizen” is misplaced or if “citizen” should be capitalized. However, without additional sentence details, option D) No change needs to be made appears to be the safest recommendation. This would be in line with the principle of not placing a comma after a subject and acknowledging that capitalization (option B) typically only occurs if “citizen” starts a sentence or is part of a proper noun. Adding a comma after “member” (option C) was not suggested in the original context.
