"It is not always easy to see who is related to whom -- and in which ways. The following argument pertains to this question: To begin with, being a cousin of Sara is sufficient for not being a workmate of Kimberly. Moreover, every cousin of Sara is a workmate of Kimberly or, otherwise, neither a workmate of Kimberly nor a daughter of Valerie. Therefore, no cousin of Sara is a daughter of Valerie."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
