A. He thought that people might be more willing to believe news agents than the government.
Explanation:
When the Jewish people were discriminated against by the German Nazis, the world media would become one source of world exposure. Despite government admissions and information, the media reports would become the unlikely source of information that the public would rely more on upon. These American correspondents would report on the rise of the Nazi regime in Germany.
The reports about the Holocaust by American news media by various war correspondents would gain public recognition. Reporters such as Edward R. Murrow from CBS and Joseph Pulitzer would become the major reporters of the Holocaust and the atrocities committed to the Jewish people. So, inviting these media agents to tour the concentration camps will enable the people to understand and know the truth about such evil acts, with the belief that people will be more willing to believe the news agents than the government information.
