Learning rate decay in Quiz

Need clarification on the answer to the quiz question on “Which of these is NOT a good learning rate decay scheme?” Shouldn’t the answer be {moderator edit - quiz answer removed} as alpha will keep on increasing (expectation is that it should decrease) as t increases?

Your reasoning sounds right to me. I tried that answer and the grader gave me the points. Are you sure you’re reading the results correctly?

I also answered the same and got 1/1 point for that question!
