"It is not always easy to see who is related to whom -- and in which ways. The following argument pertains to this question: First, not being a niece of Ashley is sufficient for being a schoolmate of Latisha and a close friend of Jaime. Second, Bernice is a schoolmate of Latisha or a close friend of Jaime. In consequence, it is false that Bernice is a niece of Ashley."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
