Answer:
The president once again proved how eloquent he was during his well-delivered State of the Union speech.
Explanation:
The words "well-delivered" imply that it was a good speech. Therefore, repulsive and impious wouldn't fit this sentence because impious means a person who's wicked and repulsive means evoking disgust. That leaves us with eloquent and consolatory. Now, eloquent meaning states "fluent or persuasive in speaking or writing." while consolatory is "making or intended to make someone who is sad or disappointed feel better." I concluded my answer from this.
I hope this helps:)
