Answer:
b.
Step-by-step explanation:
Based on Ben's idea he is stating that every potential member of the Dragon Owls project has outstanding skills in at least one respect. He seems to know that potential candidates can possess various skills that may be useful to the overall project. Since he has identified seven key skills that are detrimental to the success of the project, he basically wants at least one member of the project that has an exceptional skill level in at least one of the needed skills. That way by having seven members, each of which is exceptional at one of these skills then he would have experts in every skill to get the project done right.
