<passage>:
in the miasma of a planet without spaceflight, or sink to utter destruction! I The horses and packs were loaded before we went aboard the scoutship. The scout bay is no more than a great oversized airlock with a dozen He said what I expected. "Mia, do you want to go partners if we can get My name is Mia Havero. I'm fourteen, of course, or I wouldn't be leave that way, but George thinks it's fun to be a hot pilot. partners with the competition, do you? Besides, there was still that crack about being a snob. The planet chosen for our Trial was called Tintera. The last contact the Ship had had with it—and we were the ones who dropped them—was almost 150 years ago. No contact since. That had made the Council kids because they never tell you anything about the place they're going I felt like crawling in a corner of the ship and crying, but nobody Planets make me feel wretched. and little grubby things just looking for to crawl on. If you can think of anything creepier than that, you've got a real nasty imagination. Worst of all, planets stink. Every single one smells—I've been on enough to know that. A planet is all right for a Mud-eater, but not for me. a level or down a level and be back in civilization. When we reached Tintera, they started dropping us. We swung over the sea from the morning side and then dropped low over gray-green forested hills. Finally George spotted a clear area and dropped into it. They Jimmy—if he would get back alive. It's no game we play. When we turn fourteen, they drop us on the nearest colonized planet and come back one month later. That may sound like fun to you, but a lot of us never come back alive. Don't think I was helpless. I'm hell on wheels. They don't let us grow the Ship. There's sense behind it. It means that everybody on the Ship keep the population steady. I began to check my gear out—sonic pistol, pickup signal so I could be identify. they dropped the colonies. I say "they" because, while we did the actual dropping, the idea originated with the whole evac plan back on Earth. Considering how short a time it was in which the colonies were established, there was not time to set up industry, so they had to have draft animals. as well as the two that were being built then, went up with everything else in the Solar System in 2041. In that sixteen years 112 colonies were planted. I don't know how many of those planets had animals that could have been substituted but, even if they had, they would have He said, "What be you doing out here, boy? Be you out of your head? There be escaped Losels in these woods." I told you I hadn't finished filling out yet, but I hadn't thought it everybody here spoke the same way.

The thing is that inside it, hadn't seemed smart enough to count to one, let alone do any work. But it relieved me. I thought they might have been eating them or something. I decided I'd not tell anybody different until I found what made the closed my eyes until it passed. The first thing you learn in school is that if it weren't for idiot and criminal people like these, Earth would never have been destroyed. The evacuation would never have had to take place, and eight billion people wouldn't have died. There wouldn't have been eight billion people. But, no. They bred and they spread and they devoured everything in foresight to see what was coming. If it hadn't been for them and some others like them, there wouldn't be any humans left anywhere. And I wouldn't be here. That may not scare you, but it scares me. What happened before, when people didn't use their heads and wound up blowing the Solar System apart, is something nobody should forget. The older people don't let us forget. But these people had, and that the Council should know. For the first time since I landed on Tintera, I felt really again. I couldn't help wishing for Jimmy D. Whatever else he is, he's smart and brains I needed. How do you find out what's going on? Eavesdrop? That's a lousy method. For one thing, people can't be depended on to talk about the things you want to hear. For another, you're likely to get caught. Ask somebody? I'd had two bad shocks on this day, but they weren't the last. In the late afternoon, when the sun was starting to sink and a cool wind was starting to ripple the tree leaves, I saw the scoutship high in the sky. The dying sun colored it a deep red. Back again? I wondered what had gone wrong. I reached down into my saddlebag and brought out my contact signal. The scoutship swung up in the sky in a familiar movement calculated to drop the stomach out of everybody aboard. George Fuhonin's style. I triggered the signal, my heart turning flips all the while. I didn't Not too different, but not ours. One more enigma. Where was it from? Not here. Even if you know how, and we wouldn't tell these Mud-eaters how, a scoutship is something that takes an advanced technology to build. I felt defeated and tired. Not much farther along the road, I came to that moment that it wouldn't even seem out of the ordinary to these nice little girl, and to get rid of the kid, she sent her on a phony errand into the deep dark woods at nightfall. I could appreciate the campfire. I got up and eased away as Horst and his men came up to the fire, and cut back to where Ninc was parked. I grabbed up my blankets and mattress and started to roll them up. I had a pretty good idea now knew I'd goofed. "Boy, boy. Don't talk about the courts. I be doing you a favor. I be taking what I can use of your gear, but I be letting you go. You go to court and they'll take everything and lock you up besides. I be leaving "Why would they be doing that?" I asked. I slipped my hand under my jacket. "Every time you open your mouth you shout that you be off one of the Ships," Horst said. "That be enough. They already have one of you brats in jail in Forton." I was about to bring my gun out when up came Jack leading Ninc, with "Don't make any noise," I said, "or you'll fry. Now hand it over." I stowed it away, then paused with one hand on the leather horn of the saddle. "What's the name of the kid in jail in Forton." "I can't remember," he said. "But it be coming to me. Hold on." that my ears rang. "You dirty little punk."

<question>:
What does Mia discover about the people of the planet Tintera and why does it scare her?

<options>:
A The Tinterans are free birthers. Free birthing is breeding without restraint, which is how the Earth became over populated. This is what catalyzed the wars that eventually destroyed the solar system.
B The Tinterans have begun exploiting Losels for labor, which is against the laws of The Council. Mia knows she will have to report this back to the council, and that this will foster hostility between the scouts and the Tinterans.
C The Tinterans have learned how to build a space ship. Successfully launching a ship means that they are now a threat to the people who live in space, like Mia.
D The Tinterans know that scouts have invaded their planet, and are planning to round them up and put them in jail.
