I have to say...
I encountered an original question!
Compared to finding that misshapen humerus in the classroom, this difficulty... obviously wasn't high since both male and female skeletons could be labeled incorrectly.
With that in mind, Chen Gong spent 10 minutes observing, then returned to his seat to start writing.
