When cecilia is listening to her partner, she occasionally interjects, "oh, i see" or "uh-huh" during the interaction, cecilia is using backchannel talk?

If this is a true or false question, the answer would be true. Backchannel means describing the behavior of the listeners during a verbal communication. Hope this is the right answer for this question and would be of big help.

world war i had a devastating effect on german-americans and their cultural heritage. up until that point   german-americans, as a group, had been spared much of the discrimination, abuse, rejection, collective mistrust experienced by so many different racial and ethnic groups in the history of the united states. indeed, over the years, they had been viewed as a well integrated and esteemed part of american society. all of this change with the outbreak of war.
