This is a question from my English exercise book:
Choose the best answer A, B, C or D to complete the following sentences.
In the article, he ____ that the problems in the refugee camps are getting worse.
A. wrote B. had written C. writes D. has written
I checked the source and found it was from Cambridge Dictionary (link). Would it be correct if I use the past simple tense 'wrote' in this case to indicate the action already finished / completed in the past? I don't understand why the present tense 'writes' is used in this case. Could you explain the purpose of this?
