this is a matter of opinion. the question doesn't specify a character or situation. think about your friends and what traits they have that you value, then write a short answer as to why you value those traits. for instance, if you value your friend's loyalty, explain why this is beneficial to you or why you feel that that makes them a better person. then you have to decide what traits are stronger. is loyalty a stronger trait then, say, kindness? if you feel so, write about why this trait is "more effective" than the others.
