Hey Graeme,
The passage starts by saying “Everyone in the waiting room at 9am just registered for the tennis clinic”. The answer B goes on to mirror this (in my view). Is this wrong because we must answer what is also true rather than what is already true?
Best regards,

Hi Amaresh,
That’s not why B is wrong. B says that everyone sitting there registered ONLY for a beginners tennis clinic. All we know is that they had registered for the tennis clinic, but there’s no textual support that tennis is the only clinic they registered for. So B assumes something that the stimulus does not say. Hope that helps!
