This is called using context clues.
Hello. You did not enter the text to which the question refers, which makes it difficult to accurately compose an answer. However, I will try to help you in the best possible way.
A context clue occurs when you don't know a word, or one of its meanings, but the entire text, or another word in the same sentence, presents you with a context that allows you to understand what the unknown word represents.
In the case of your question, you should look for a word in the sentence that is related to the word "mission" and that is contextualizing it. Esssa is the context clue.
It seems like A or B but more for the answer B
Answer:
just plain folks
Explanation:
Propagandists use different techniques and ways to relay messages and influence/convince others.
just plain folks makes the voters think the candidate is just like them, that they share the same desires and concerns..
The plain folks technique is designed in such a way that ordinary voters would end up identifying with candidate that they share no similiarities with. For example, a candidate may come from very wealthy background, but to win voters on his side he presents himself as a humble person by doing those things that the plain folks do.
