    That egg cartons are among the easiest food containers to make implies that there may be other food containers similar to egg cartons.

  2. Out of Scope4% picked this

    The statements only discuss the level of cleaning required of used Styrofoam in order to make suitable food containers for different kinds of food. It does not speak to whether there are some foods that cannot be packaged in containers made from recycled Styrofoam.

  3. Out of Scope11% picked this

    The reason why used Styrofoam must be thoroughly cleaned when recycled is to not discussed in the statements.

  4. Too Strong8% picked this

    While the statements suggest that some egg cartons are made from recycled Styrofoam, they do not go so far as to suggest that most egg cartons are made from recycled Styrofoam.

  5. Correct72% picked this

    Not every type of food container made of recycled Styrofoam is effectively prevented from coming into contact with

    Why this is right

    We always rephrase "not all A's are B" into "Some A's are not B". This is saying, "Some containers made of recycled Styrofoam do NOT prevent the container from contacting the food", i.e. "some recycled Styrofoam containers contact the food that's in them". This sounds like an obvious and weak statement in the real world. It's very very plausible. And it's supported by the fact that we know that when food doesn't have a built-in buffer like an egg shell, we worry about cleaning that recycled Styrofoam more thoroughly. Why would we worry about cleaning it, unless we were thinking, "the food is going to be touching this Styrofoam"?
