Final answer:
The critical tone toward adults in Langston Hughes's 'Salvation' is primarily shown through the juxtaposition of adult excitement and child confusion.
Step-by-step explanation:
In Langston Hughes's Salvation, the critical tone toward adults is most contributed to by the juxtaposition of the adults' excitement with the children's lack of understanding. This technique illustrates the pressure felt by the children to conform to the expectations of the adults, which in turn portrays the adults in a critical light. Hughes highlights this tension to show the disconnect between the adult's perceived religious experience and the actual emotional understanding of the children involved.
