Hi,
I'd change these:

5. The sun was eclipsed by the moon. ACTIVE PASSIVE
9. This bone has been buried by the dog. PASSIVE
10. It takes a long time to think of these examples. PASSIVE ACTIVE
13. There was a cup of coffee on the table but now it's gone. ACTIVE
15. Mark was given one month to write this book. ACTIVE PASSIVE

As far as your #14 is concerned, I am not sure everybody would agree on this. Emotion: smile

14. I was born under a wandering star

I was taught that this is technically a passive form, but some regard it as active (Cambridge dictionary lists the verb "be born "). For instance, here's what some of our most prominent members wrote in the forums. (Opinions are split)

Clive (from this post ) ...
Quaid-e-Azam was born on 25th of December.
Technically, it's already passive.
Active voice would be 'His mother bore him on 25th of December'. The infinitive form of the verb is 'bear', and 'born/borne' is the past participle.
It's an odd verb because usually, when we say 'He was born . . ', we think of 'born' as an adjective.

... Philip (from this post ) ...
"I was born" is not really a passive voice construction. It is the simple past of the verbal expression 'to be born'. "To bear" can be used passively, "as he was borne of the Virgin Mary", meaning "carried".
... Alphecca Stars (from this pos t) ...
When the focus is on the offspring or on something brought forth as if by birth, born is the standard spelling, and it occurs only in passive constructions:
My friend was born in Ohio.
No children have been born at the South Pole.
A strange desire was born of the tragic experience.

... and Avangi (from this post )
The tricky, confusing thing is that we're talking about the verb "to bear."
Present tense: She bears another child every year.
Past tense: She bore me a sister in 1975.
Future passive: How many children will be born in 2010?
(All passive voice tenses use the same past participle.)
I am born. I shall be born. I was born. I shall have been born, etc.
