Answer:
2. This World War II advertisement shows the famous boxer Joe Louis with the caption “We’re going to do our part . . . .”
Step-by-step explanation:
Celebrities and beautiful people tend to have a big influence on ordinary people in a country. Many people have celebrities and other beautiful people as a source of admiration, so it is common for the government to use these people for some ideologically biased propaganda. In wartime, it's no different.
In wartime, celebrities and beautiful people can be used to influence the common people to support the country and join the army. The government shows these people doing very patriotic things and joining the military so that ordinary people have thoughts like "if he thinks it's right, it probably is." An example of such propaganda can be seen in the number 2 from the options shown above.
