The correctly punctuated sentence is: “Put your science projects next to the seventh graders’,” he instructed.
The other sentences have punctuation errors or incorrect use of apostrophes. Here's a breakdown:
- “That dog is the Jones,” my neighbor said. (Incorrect use of "the Jones" — it should likely be "the Joneses" if referring to a family.)
- “Please hand out the worksheets to the students’,” the teacher told me. (The apostrophe is misplaced; it should be "students.")
- “Those backpacks are my sisters,” Callie said. (The apostrophe is misplaced; it should be "sister's" if referring to one sister or "sisters'" if referring to multiple sisters.)
However, based on the phrasing you provided, “Put your science projects next to the seventh graders’,” he instructed is the only one that is punctuated correctly.
