Discussion - Forest for the Trees.

Discussion not a paper. cite all references. Please use proper English.

"The paper's content is jumbled and is partially in second person and uses unusual wording together as if it was a machine translation from a foreign language to English'.

Due to this I am failing some classes. instructions as follows: "Read the following question and post your answer to the discussion board.

Thinking about that mapping process, which aspect of the Galaxy 's structure do think is our most interesting - or hardest to understand - discovery?"
