You are the owner of a company that sells cleaning products. The people in research and development have two new products for you to review. The first is a type of hand soap that they say cuts grease because "it is from lipid and like dissolves like." The second is a laundry detergent that is supposed to get out grass strains very well because "it uses a protein and protein gets out proteins." Using your knowledge of macromolecules, this job evaluates these claims and gives the reasoning behind the decision to approve one, both or neither of these projects.
