Which accurately describes the south's strengths at the beginning of the civil war? ?

I believe the correct answer is - The South had numerous experienced military officers to lead its army.
The other options are incorrect because:
- not all food crops came from the South; a lot of them came from the North
- the North had a far superior government
- the North had better roads than the South
This leaves us with military officers, who were indeed an asset the South had during the Civil War. 

I would go with A. I am sure that it is correct, because he was the first one to examine, and the first to accurately show the description of the human body.
Hope that this would help you! =)
