Why is 'hall' not accepted. It is given as a hint.
Why doesn't énorme come before rat? I thought BAGS (beauty, age, goodness, and SIZE) came before the noun. Énorme is definitely a size adjective.
"Énorme" is not part of the BANGs adjectives. You can place it before or after the noun it modifies.
Before the noun, it is your opinion only (subjective/relative) and after the noun, it is what most people would agree on (subjective/factual).
