Please provide the passage so that I can help :)
They ask the priest to sprinkle holy water on the grave so the old man’s spirit will make it rain.
When the priest is asked to home to the burial with the holy water, the priest initially refuses since the family did not ask him to say the funeral rites or have Mass. Leon, who comes to get the priest says, "we just want him to have plenty of water." Then the last line of the story says, "he was happy about the sprinkling of the holy water; now the old man could send them big thunderclouds for sure." From this we can infer that the people expect Teofilo to make it rain now that he has died. This also connects with the title of the story.
According to Mark Dyble, the dawn of agriculture gave rise to the practice of polygamy.
Polygamy is having many spouses. It usually is a man having many wives.
The society before was an egalitarian society. This is a society for a gatherer-hunter community. This society treats everyone as equal.
When they began to find land and settle down to farm the land, men no longer wanted to become equal. They wanted to acquire more possession. They wanted to have more wives and more children. Thus, polygamy practices arise.
In the first book, the Capitol forces the last players together by draining the river/stream which forces them to go to the lake near the cornucopia if they want access to water.
