Hi. Silly question. I'm pursuing the Dowling method. A week ago I finally passed the Dowling Wheel using the online tool, and I'm making a go at LLPSI. Right in Cap II I've run into a question. These two sentences: Quis pater Mārcī est? .... Quae est māter Mārcī? The first makes sense to me, but I thought 'Quae' was plural: (https://en.wiktionary.org/wiki/quis#Latin). Shouldn't they both be 'Quis'? m-f-n singular: quis-quis-quid | m-f-n plural: quī-quae-quae no? What am I missing?
