question:  How have increasingly longer life spans impacted Federation society?
context: They were such cute synthetic creatures, it was impossible not to love them. But think—we get this house rent-free; I've got my own district with no bosses around; I make my own hours; you'll meet lots of people that stop in at the pound. If I don't want to follow my aptitudes, the only choice is common labor. And because I have a B.S. in biology and an aptitude for dealing with people. Honey, before the evolvotron, before Anthropos went into the mutant-animal business, people used to elect dogcatchers. The suburban street wound among the pastel plasticoid cottages that were set approximately two to an acre on the lightly wooded land. With its population legally fixed at three hundred million, most of the country had become one big suburb, dotted with community centers and lined with narrow belts of industrial development. A class-C couple, allowed no children of their own, could get quite attached to a cat-Q-5. The felines were emotionally safer than the quasi-human chimp-K series called "neutroids." When a pet neutroid died, a family was broken with grief; but most couples could endure the death of a cat-Q or a dog-F. Class-C couples were allowed two lesser units or one neutroid. This could be a ruse to bring a stop to investigations when one animal is found. If allowed to reach age-set or adulthood, such a deviant could be dangerous to its owner or to others. Its replacement-quota of new neutroids was around three hundred animals a month. He tried to estimate how many of July's influx had been K-99s from Bermuda Factory. You're welcome to it, Doctor, but you can't fake a serial number. Only thirty-five of July's Bermuda-K-99s had entered his territory, and they were about equally divided among five pet shops, three of which were in Wylo City. The robot operator, which had on tape the working habits of each Wylo City citizen, began calling numbers.
output:  The population is tightly controlled to prevent scarcity.
options:  The population is tightly controlled to prevent scarcity.  Mutant animals have been created to satisfy the parental desires of childless couples.  Life expectancy has increased to 80.  The whole country has become a giant suburb, with two houses on every acre.
