Question

\i cant believe that you put your sneakers in the oven,\ complained teresa, toms wife. completely frustrated, she added \it will take me all afternoon to scrape this melted rubber off the rack.\

add a comma between added and it.
no change is necessary.
remove the comma between oven and complained.
remove the comma between teresa and toms.

Explanation:

When a dialogue tag like "she added" comes before a direct quote, a comma must separate the tag from the start of the quoted sentence. The original text lacks this comma between "added" and "It", which is a grammatical error. The other options are incorrect: the comma after "oven" is proper for separating a quoted phrase from its dialogue tag, the comma between "Teresa" and "Tom's" correctly sets off the appositive phrase identifying Teresa, and the text does need a change.

Answer:

Add a comma between added and It.
