Passage: One day I was hungry and checked my refrigerator for something to eat . I found a plate of mixed meat and vegetables and decided to heat it in my microwave . The plate was microwave safe , so I did n't need to move it to another container . After checking that the microwave was clean inside , I put the plate in the microwave and placed a plastic microwave cover over it . I then set the timer for automatic heat . This way I did n't need to figure out how long it would take . The microwave did it for me . After about a minute or so the microwave made a dinging sound letting me know that my food was ready . Steam rose showing that the food was very hot . I was careful when I started to eat so I would n't burn my mouth . Question: What did they take off? Option1: the mixed meat Option2: the plastic cover
the plastic cover
