I believe the correct answer is: The narrator's superior
pigs and his demand that the villagers pay for the damage done to his pigs
creates tension between the narrator and the villagers.
In this excerpt from the story “In a Native Village” from
the “Ridan the Devil and the other stories”, written by Louis Becke, main
conflict begins with narrator’s conviction that his pigs are superior and had
done no wrong to other villagers when they escape from his property:
“Next
morning the seven piglets were returned one by one by various native children.
Each piglet had, according to their accounts, been in a separate garden, and done
considerable damage… I gave each lying child a quarter-dollar.”
Their next escape resulted in losing their tails while
confronting the other pigs, for with the narrator demanded a considerable
payment as he regarded this as their escape from the “cruel death”. This
situation cumulated the tension between the villagers and the narrator and
resulted in their fraud and narrator shooting his own pig.
Therefore, I would say that the narrator advances the plot of the story with
his demand that the villagers pay for the damage done to his superior pigs,
which creates tension between the narrator and the villagers.
