You work for a company that manufactures food products. A new "wonder food" is being distributed by a rival company.

a. includes proteins.
b. could only be made of carbohydrates.
c. could only be made of triglycerides.
d. does not include proteins or nucleic acids.

At this point, your researchers can say with certainty that the food INCLUDES PROTEIN.
