George c. parker, a con artist from around the 1900s, conned others into buying the brooklyn bridge, the statue of liberty, grant's tomb, and the metropolitan museum of art. how should the sentence above be changed to demonstrate the correct use of quotation marks? a. the word "buying" should be in quotation marks because it is an ironic use: parker wasn't authorized to sell those landmarks, and the people who gave him money didn't really buy anything. b. the titles of the famous landmarks should be in quotation marks because they are large and well-known. c. the words "conned others" should be in quotation marks for special emphasis. d. "a con artist from around the 1900s" should be in quotation marks because it is a direct quotation.
