Translation:I would have made a cake if I had had time.
Don't trust in the pronunciation of "bolo" because it's wrong. I reported this for duolingo. Although, "bolo" seems like "bowl" with the "o" in the end, I could write "bowlow".
That's it. I hope it helps someone.
Listened to "bolo" + ten times and still did not make out the word. Still bad audio Dec 15
