Explanation:

Plastic, styrofoam (a type of plastic), and gas (like natural gas which can be associated with petroleum - related processes in some contexts) are related to petroleum in terms of their production (plastics are made from petrochemicals). Paper, on the other hand, is mainly made from wood pulp (through processes like pulping and bleaching) and not from petroleum.
