A K Warder Exercise 7

Hi All:
Happy new year to you all. Hope you had nice holidays.

I am reading Warder and am stuck now at Excercise 7 where
the 'solutions' to all questions end.

On page 43,

desito Aananda mayaa dhammo

What does it translate to?

1. What is taught, O Ananda, by me dhamma -->

2. O Ananda, I teach dhamma.

3. O Ananda, I have taught dhamma.

Is this about right? Or the agent here is Ananda? What should be the
right translation?

Thanks in advance,
jaran

PS What do numbers on pp 465 on-ward refer to?
