This week's advanced grammar quiz
For those of you that enjoyed the challenge of last week's 'advanced grammar quiz' here's a new one for this week. (Not everyone's cup of tea I know.)
Also if you'd like some audio practice there is also a quiz to go with the audio recording.
I hope that they are helpful and please do leave feedback and let us know how you get on.
Also if you spot any errors feel free to let me know as I really appreciate it.

Question 12, I think it was, the English would surely be ' they'?? Estos disfrutaban.. They benefited..
I did see one small error... #2:
How would you translate 'por es' in the context of the second sentence?
Should be 'por eso'.
Thanks for the quiz!
It seems like a great quiz. I just wanted to mention that I had never heard the term "one off event" before. Thanks for the chance to practice!
