Hi, Samantha! Thank you so much for writing out your questions so cleary, you make it so much easier and that is much appreciated! The wording of this question has now been updated to make it more clear as it could have been interpreted in two different ways, which is why there were two different answers in the key! Your answer is correct which signifies the timeline of the patients medical history, starting with Liver Qi Stagnation which would have Wood invading the Spleen resulting in a Spleen Yang Deficiency over time, and as the Earth generates Metal that resulted in a Lung Qi Deficiency, which progressed even further to a Kidney and Heart Yang Deficiency with Water overflowing to the upper Burner. Well done, Samantha – you’re right on track for your exams! – Kylie
