There is a section in the TOEIC Speaking & Writing Test where you are supposed to describe a picture.
Let's say there is a picture of a man holding a cell phone at a refinery (an example question from the internet).
I would write: A worker is holding a cell phone at a refinery.
But the example answer always had "the" instead of "a" (as in "the" worker is holding a...)
I think both articles suffice for answering, right?
Thanks in advance.
I would follow the pattern they use, but the indefinite article is OK there.
