Answer:
B. to narrate past events
Explanation:
The verb tenses used in the following sentence from the story: "In the past they had sometimes been treated to three-legged creatures from Venus" are used to narrate past events.
This is because, events that have already happened are being narrated.
I think it is c because abrasive can be to scrape and abound can be to exist in great quantities or numbers.
It would be "house is what" because "is" would need to be changed to "are".
