Working in a fast production line requires not only physical strength and quick reflexes but presence of mind. In instances when the operating machine jams, you need to decide quickly to either temporarily pause the production and call an expert to fix the machine to avoid further delays or fix the machine by yourself. The first option is the more sensible one.
Well it really depends.
If you are describing a 12 year old girl, with brown hair and brown eyes it could go something like this:
"The young, twelve year old girl, had long brown curls that fell to her shoulders. Her chocolate brown eyes were as dark as her hair and stood out on her pale, freckled skin. She was - in short - lovely."
If you are describing... let's say... a 16 year old boy with black hair and blue eyes it could go something like this:
"The young man turned his crystal blue eyes in my direction and I looked away quickly so as not to be caught staring. "How old are you?" He asked. "Sixteen," I replied timidly, twirling my long hair around my finger. "Me too," He replied, flicking his shoulder length black hair out of his eyes."
There are no answer choices available??
"Sitting on the park bench" is the dangling modifier. Who is sitting on a park bench? Is it the sun? It does not make sense because you don't have a subject.
