Answer:
Dragons are real because all the other animals on the calendar are real.
Step-by-step explanation:
The author talks about finding evidence that dragons are not only mythical creatures, but that they are actually real animals that truly exists. She lists all the evidence she has found to confirm this – there are animals in many different cultures mentioned in various moments in history. They are also in the Bible, as well as in real accounts of Marco Polo’s travels.
She then says she also has seen dragons along with other real animals in the Chinese calendar. For her, this is the proof. This is for her one more evidence that dragons are real – if other animals on the calendar are real, then also dragons should be real.
"Dragons are included along with eleven real animals." in the context of proving that dragons are real are used as evidence of their existence.
