Thank you, everyone, for your kind responses. I sincerely appreciate the help.

I must apologize, as I misstated something above. Not enough sleep.

I am not comparing averages. I meant to say that I am comparing those percentages across the columns for groups A and B.

The key is that each group read something different. I am looking for significance in the difference between the two groups at each level of the Likert, so that we can know whether the choice of reading material had significant effect on the respondents' Likert rankings.

*How interested are you in this place after reading? *
Reading A group Reading B group

I am definitely interested 27.2% 19.4%

significant difference here?
I am somewhat interested 45.6% 35.2%

or here?
I am neither interested nor 24.3% 36.1%

etc.
uninterested

I am somewhat uninterested 2.9% 8.3%

I am definitely uinterested 0.0% 0.9%

I have several questions like this sample above.

The Mann-Whitney looks like a possible fit for what I am doing, but I am not sure. Does everyone concur on that one?
