The option sounds simple enough. I assume it indicates that the bounty starter wants an answer that draws from or is supported by canon. But the description underneath it seems odd. It reads:
The question is widely applicable to a large audience.
How does that relate to wanting a canonical answer? The rest of the description is also a bit confusing.
A detailed canonical answer is required to address all the concerns.
Maybe I'm reading too much into the word choice here but couldn't "to address all the concerns" simply be "to answer the question"? How does a question having a lot of concerns relate to wanting an answer that is supported by canon?
