1.______ anonymous caller helped ______ local police crack ______ difficult case that had remained unsolved for years.
Which article correctly fill these blanks ? I am trying to set an article question, but am confused as to what the correct answer is.
An/The anonymous caller helped a/the local police crack on a difficult case that had remained unsolved for years.
I am not a teacher. Could you check the sentence for us?
Thanks
Thanks for the replies.
Typo in the earlier post - *articles
The first and last bank are "An" and "a" respectively.
However I am a little confused about the use of "the" in the middle blank. I would like a clarification as to when the article should be used, and when not.
