Which sentence contains an error in the negative commands-and-requests structural contrast?
The ranger asked the campers not to feed the ponies near the fence.
The doctor told Raj not to drive until his vision had cleared.
The curator told the movers that not lift the cabinet by its handles.✓Correct answer
The usher asked the audience not to block the side entrance.
Explanation
The curator sentence is erroneous because told the movers that not lift uses an ungrammatical that-plus-bare-verb structure. A negative reported command needs the recipients followed by not to and the base verb.
