Basketball is good, and writing it on your file or resume will make you more team-oriented. But also can keep the body in good condition. Besides, loving sports makes you look more sunny and more popular at school. Singing well is also a good advantage. Singing on any occasion is very useful. Having your own opening song helps to avoid the embarrassment when you ask for a performance, so you won't play singing. But I personally think basketball is better. It can also cultivate the feelings between you and your friends and classmates.
