The comparison of televised war images vs. claims of government officials best represents the "credibility gap" during the Vietnam War.  

Explanation:

The "credibility gap" was a social phenomenon that occurred during the Vietnam War, through which society did not believe in what the government was saying about the results of the war: the Lyndon Johnson government spoke of positive results, with optimism and triumphalism, relying on the media that operated in his favor; but society, on the other hand, viewed the war with a bad eye due to the large number of Americans killed or wounded in the conflict, thereby believing all that victorious paraphernalia that was being attempted to establish from the sectors of power.

This lack of social support, added to various tragic events caused as a consequence of this unrest (such as the Kent State University Massacre) ended up bending the government's position and forcing it to end American participation in the conflict.

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
