Self-study
Of the various food containers made of recycled Styrofoam, egg cartons are among the easiest to make. ███████ ███ ██████ ████ ███ ██████ ████ ██ ██ ████████ ████ ████████ ███ ██████████ ████ █████████ ████ ███ ██ ██ ██████████ ███████ ████ ████ ████ ███ ███████ ██ ████ ████ ████ █████ ████ ███████████
Summary
The stimulus states that egg cartons are among the easiest food containers to make from recycled Styrofoam because the eggshells prevent the food (the eggs) from directly contacting the Styrofoam. Therefore, used Styrofoam doesn't need to be as thoroughly cleaned for making egg cartons as it is for making other food containers.
Strongly Supported Conclusions
Eggs in a carton make contact with the Styrofoam, but it does not matter because they are in a shell.

Which one of the following ██ ████ ████████ █████████ ██ ███ ███████████ ██████
a
No food containers █████ ████ ███ ███████ ███ ██████ ██ ████ ██ ████████ █████████ ████ ███ ███ ████ ██████████ ████████
This is too strong to support. There is no information as to whether there is or is not another type of food that does not need its Styrofoam packaging to be thoroughly cleaned.
b
There are some █████ ████ ██████ ██ ████████ ██ ████████ █████████ ██ ██████ ███ ███ █████████ ██ █████████
The stimulus does not mention a food that absolutely cannot be packaged in Styrofoam. You have to make several assumptions for this to work.

The main reason █████████ ████ ██ ██████████ ███████ ████ ████████ ██ ██ ██████ ███ ████████ ████ ████ ███ ████ ████ ███████ ████ ███ ██████████
This is too strong to support. Perhaps removing residual foods is a reason, but there is no indication that it is the main reason.
d
Because they are █████ ███ ███████ ████ ██████████ ██ ████ ████ ████████ ██████████ ████ ███ ███████ ███ ████ ████ ████████ ██████████
There is no mention of what most egg cartons are made from. The stimulus says that egg cartons are among the easiest to make from recycled Styrofoam.

This is definitely hard to parse through, but it is supported. The stimulus acknowledges that egg cartons (a type of food container) come into contact with the eggs (food it contains).
