35? Probably less than 50/50 that that will be right. Unless you are required to have 100% or be punished I would take a guess and note that it was not clear where to find the info. Hopefully the examiner will illuminate where to find the answer. Depending on where you are, sometimes there isn't an answer, only a goose chase to see how you chase geese.
These exams are frustrating at times, don't bog down on the minutia, keep a clear view of where you are going.
Cheers.
