I think that Shakespeare is referring to Winter. I think so because he says,
“Yellow leaves, or none, or few do hang. Upon those boughs which shake against the cold.” Which means that the leaves are falling off of the trees and also that the tree stumps are shaking against the cold. All these things happen is winter. Hope this helped!
D is correct because it was the beginning of the conversation and also because unlike C, when the guard shouted "or" it wasn't the start of the conversation but a continuation so it didn't need capitalization.<span />
The answer would be d because music doesn't necessarily require physical activity unless you are in the marching band. Hope this helped! :)<span />
