This is a question from my English exercise book:
Choose the best answer A, B ,c or D to complete the following sentence:
I _____ through the booklet but couldn’t find the address.
A. scanned B. scan C. have scanned D. am scanning
Even the answer key is 'A. scanned', I think 'C. have scanned' is also possible. In my opinion, both the present perfect (have scanned) and past simple (scanned) in this case indicate an action / event started and finished in the past.
I would appreciate if you could tell me whether my understanding is correct or not.
