On Level 9 of French 1 (Memrise course), I believe the French needs to be fixed. Refer “est-ce que vous êtes prêt”. IMO the it should read, “est-ce que vous êtes prêts”. If someone suggests it’s formal singular - that’s fine except it doesn’t specify that. At a minumum the addition of the ‘s’ should at least be added as an alternative answer, meaning prêts (not prêt). Merci beaucoup.
