The 'Type what you hear' exercise sound like Mwili mwahitaji lishe. Which obviously makes no sense.
How do we tell whether this translates to "A body..." or "The body..."?
In this course: just guess and hope for the best and if they haven't included both possibilities, use the report function.
Why u in unahitaji and not i???
"Mwili" is a class 3 (singular) noun, so the subject concord is -u-
The plural "miili" would take an -i-
Your audio has very poor diction
