Midway through the parade, the rodeo queen from New Mexico
appeared — a red sash across her chest, a crown hugging the band of her cowboy hat; she rode in circles on her gray horse, waving at the crowd as if she knew each of them personally.
A. appeared — a red sash across her chest, a crown hugging the band of her cowboy hat; she rode in circles on her gray horse, waving at the crowd as if she knew each of them personally
B. appeared — a red sash across her chest and a crown hugging the band of her cowboy hat; she rode in circles on her gray horse and waving at the crowd as if she knew each of them personally
C. appeared — a red sash across her chest; a crown hugging the band of her cowboy hat; she rode in circles on her gray horse and was waving at the crowd as if she knew each of them personally
D. appeared with a red sash across her chest, a crown hugging the band of her cowboy hat, she rode in circles on her gray horse and was waving at the crowd as if she knew each of them personally
E. appeared with a red sash across her chest and a crown hugging the band of her cowboy hat, rode in circles on her gray horse, waving at the crowd as if she knew each of them personally
This is indeed a daunting question to especially those non-natives who may not have heard of 'asyndeton' before. I was under the impression that the two modifiers are co-ordinate adverbs (which do not require to be conjugated with a conjunction) describing how the queen appeared. Still, we may try other roads to reach our Rome.
Choice B is unparallel with a clause before 'and' a phrase after.
Choice C is un-stylistic since a semicolon is not used unless there is a distraction from the presence multiple commas in a sentence.
Choice D is a run - on with no conjunction between the two ICs
Choice E is unparallel with no conjunction between the two verbs
What remains is A.
Incidentally, --waving at the crowd as if she knew each of them personally-- is common to all the five choices. Why underline that phrase unduly?
