Translation:This young police officer has three sons.
It is still insisting on "policeman," and "police officer" was rejected. I reported it and checked "my answer should be accepted." But can someone tell me if the person who gets my report will know what I entered? If not, then how will they know which part of the sentence I'm referring to?
The "my answer should be accepted" is the best thing you can do. It looks like the moderator gets your answer then, and just has to push a button to add it to the list of accepted answers.
Which occasionally results in inconsistent formatting if the learner who reports it isn't too keen on placing proper punctuation and the moderator is too unwilling to edit it. :)
