For EIGRP, "participate in" implies that it is part of the EIGRP process/neighbor relationships. That is where the passive-interface/no passive-interface component comes into play. It is the interfaces with those subnets which will become EIGRP neighbors. The network statements dictate which routes will be passed between neighbors. The wording in the requirement can be a bit confusing. Sometimes that's on purpose; sometimes it just works out that way :)
