8 - A 13 - C 20 - B 22 - B 27 - D 30 - C
The answer is A. Tú tocas el piano. Because Tu tocas is the only correct way of saying you are playing the piano in this instance. C is saying "tocan" which is wrong because it's saying you but then using a the group form of playing. The same thing with B, it's also using the group form of playing and it's past tense. And D is using the I form of playing not the you form.
Your supposed to answer what the people on the first column buy (insert in second column ) (I think your supposed to make something up) and then type how they payed for it (third row) (ex. Credit card, as shown in the last row).
