Saxophone<br>Brendan loves listening to the Saxophone. He really wants to learn how to play. He has looked every where for a cheap saxophone. One day he finally found one he could afford. He was late getting to the store, and someone else already bought it.
Brendan is learning to play the saxophone
The context only says that he is looking to buy one, not that he has started learning yet. It also may be that he is buying a saxophone for someone else to play. The system could likely not differentiate between wanting to play and actually playing
