Final Answer
In this sentence, the word "consumer" means a person who eats or uses something.
Explanation
The word "consumer" is formed by combining the root word "sum," which means to take in Latin, with the suffix "-er," denoting a person or thing that does something. In this case, "consumer" refers to a person who consumes or uses something. The sentence, "Because of these concerns, many consumers want to know if the food they eat contains GMOs," indicates that individuals who eat or use products are interested in knowing whether the food they consume contains genetically modified organisms (GMOs).
Understanding the etymology of the word provides insight into its meaning. The root "sum" implies taking or using, and the "-er" suffix indicates a person who engages in the action. Therefore, a "consumer" is someone actively involved in the act of using or eating products, aligning with the context of the sentence. The choices provided in the question are then differentiated based on the relationship between the root word and the suffix, leading to the selection of "a person who eats or uses something" as the accurate definition in this context.
In summary, the word "consumer," derived from the Latin root "sum" and the suffix "-er," specifically denotes a person who actively consumes or uses something, and this definition aligns with the sentence's context about individuals interested in the content of their food.
