Could you explain to me why there is no article before «parent» but there is the indefinite article before «meeting»? Is possible to use the article in the first case or omit it in the second?
Say whether you feel the following remark/sentences are okay, too formal or too informal <...> 2 (Parent to another parent at a school parents meeting): How many offspring do you have at the school?
This is taken from an exercise in the book «English Vocabulary in Use».
Thank you for your time.
