@shafieiava,

Let's take a look at (C) and (E).

(C) says, "The main reason Styrofoam must be thoroughly cleaned when
recycled is to remove any residual food that has come into contact
with the Styrofoam."

The problem with (C) is that the stimulus did not provide us with a
reason for why the Styrofoam has to be cleaned; it simply told us that
it had to be, so (C) doesn't have support from the stimulus. Thus, we
can get rid of it.

(E) says, "Not every type of food container made of recycled Styrofoam
is effectively prevented from coming into contact with the food it
contains."

(E) is basically telling us that there are some types of food
containers made of recycled Styrofoam that are not effectively
prevented from coming into contact with the food inside. (E) is
definitely supported by the stimulus. Egg cartons are different from
other types of recycled Styrofoam containers because the egg shells
keep the food from touching the Styrofoam, so the Styrofoam used to
make egg cartons doesn't have to be cleaned as much. This means that
with other types of Styrofoam containers, food would normally come
into contact with the Styrofoam. Thus, (E) is supported by the
stimulus, so it's the correct answer choice.

Does this make sense? Let us know if you have any other questions!
