Question

correct the text by inserting one comma. (note: in this skill, serial commas are not optional.) , after nan wood graham posed for the painting american gothic some viewers called her the american mona lisa.

Explanation:

The original sentence has two independent clauses: "After Nan Wood Graham posed for the painting American Gothic" (a dependent clause acting as an adverbial phrase) and "some viewers called her the American Mona Lisa" (the main clause). To separate these two parts for clarity, a comma should be inserted after "American Gothic" to show the break between the introductory phrase and the main clause.

Answer:

After Nan Wood Graham posed for the painting American Gothic, some viewers called her the American Mona Lisa.
