I was having a similar problem. I got "Unspecified return value" because I
was writing the string "Input is not a sentence" instead of just returning it
from the diagram-sentence function.

If you just return a string from diagram-sentence, you should not get parens
around it in the output:

(define (diagram-sentence lst)
        (cond
                ...
                (else "Input is not a sentence.")
        )
)
