Answer:(Letters going in order) B, A, B, A, B, A, B, A
Step-by-step explanation:
Firstly, why 1, 3, 5, and 7 are B
Since B is an advertisement, it have the elements of what would make for an typical advertisement which would include 1, 3, 5, and 7. Advertaisments can include elements from the other questions but in this case, they don't which is why 1, 3, 5, and 7 are B
Secondly, why 2, 4, 6, and 8 are A
All A is in this case is an informal piece, it's not trying to persuade you to do anything. And since 1, 3, 5, and 7 are taken by B, that leave 2, 4, 6, and 8 for A and they all match A because A is an informal piece. A typical informal piece would include elements from 2, 4, 6, and 8 which is why A is those things.
I hope this helps!
