why is "limonadia" pronounced as if having english vowels? that's misleading
Same question: shouldn't it sound like "limonAHdiAH"?
Why is this partitive?
Its because of the "some lemonade". Its not the lemonade but lemonade in a general sense
This implies that "some black soda pop" is the object of a sentence. If it were the subject, however unlikely, it would be in the nominative. Therefore, the exercise is a bit misleading, as it is not a full sentence.
Where does the word some fit in
I guess it comes from the partitive (extra -a at the end of the words). Since partitive is used for undefined amount of something.
