From the description, reduction happens at the Ag electrode so this is the cathode.
The Cd electrode would be the anode (equation 3 shows Cd oxidation).
I was thinking about equations 1 & 2 for the cathode, though. The passage says the oxygen is getting reduced, but equation 2 shows the higher reduction potential. Would equation 1 get flipped?
