The correct answer to this open question is the following.
Unfortunately, you forgot to attach the statements to answer the question. Without those statements, we do not know what they say.
However, trying to help you, we did some deep research and can comment on the following.
Political parties and interest groups use propaganda techniques to influence citizens. One statement that could be the best example of the "just plain folks" technique that would be used by a candidate running for office would be this: "My father emphasized the value of hard work."
This is correct because using phrases like that, the political candidate is trying to appear like "an everyday common United States citizen." This way, the candidate tries to project the image that he/she is like you and knows your necessities, and has the same concerns as you.
