Of the various food containers made of recycled Styrofoam, egg cartons are among the easiest to make. Because egg shells keep the actual food to be consumed from touching the Styrofoam, used Styrofoam need not be as thoroughly cleaned when made into egg cartons as when made into other food containers. Which one of the following is most strongly supported by the information above? ['Not every type of food container made of recycled Styrofoam is effectively prevented from coming into contact with the food it contains.', 'The main reason Styrofoam must be thoroughly cleaned when recycled is to remove any residual food that has come into contact with the Styrofoam.', 'No food containers other than egg cartons can safely be made of recycled Styrofoam that has not been thoroughly cleaned.', 'There are some foods that cannot be packaged in recycled Styrofoam no matter how the Styrofoam is recycled.']
