"A. The ancestor of the dog." is a fragment. When in doubt, say the sentence out loud and ask yourself if there is enough information for the sentence to make sense.
Answer:
- A. She includes the explicit lesson learned from Arachne’s tale.
- D. She displays Arachne’s arrogant and impertinent behavior.
Explanation:
When Coolidge told the story of Arachne, she made sure to include the arrogant and impertinent behavior that got Arachne to challenge the gods by saying she was better than Athena.
In the end Athena turned her into a spider and Coolidge makes sure to include the lesson learned from Athena's tale of arrogance being a punishable offence.
I believe the answer would be C. Hope this helps!
