I figured that he figured that I had something to do with the way he looked. "Shipping marocca to Gloryanna III didn't turn out to be a cakewalk succeed in getting the marocca to Gloryanna III?" I asked The success of that venture—even if the job had turned out to be more difficult than we had expected—meant an enormous profit to both of us. The fruit of the marocca is delicious and fabulously expensive. The plant grew only on the single planet Mypore II. Transshipped seeds invariably failed to germinate, which explained its rarity. letting any of the living plants get shipped off their planet. But when "I got them there safely," said Captain Hannah. "And they are growing all right?" I persisted. "When I left, marocca was growing like mad," said Captain Hannah. I relaxed and leaned back in my chair. I no longer felt the need of rhial for myself. "Tell me about it," I suggested. "It was you who said that we should carry those damn plants to that marocca takes a very special kind of environment. Bright sun most of the time—that means an almost cloudless environment. A very equable climate. Days and nights the same length and no seasons—that means no ecliptical and no axial tilt. But our tests showed that the plants had enough tolerance to cause no trouble in the trip in "You'll remember that I warned you that we should take some marocca out into space and solve any problems we might find before committing ourselves to hauling a full load of it?" asked Captain Hannah. "We couldn't," I protested. "The Myporians gave us a deadline. If we had gone through all of that rigamarole, we would have lost the own way, in his own time. "Well," he said, "I got into parking orbit around Mypore without any trouble. The plastic film kept the water in the hydroponic tanks without any trouble, even in a no-gravity condition. And by the time I doesn't keep winding, the plants die extra hours of night time before they run down." "Oh," said Captain Hannah in quiet tones of controlled desperation, "it was very simple. I just put enough spin on the ship to make artificial gravity, and then I strung a light and moved it every fifteen minutes for ten and one-half hours, until I had gone halfway around the room. The plants liked it fine. "Of course, first I had to move all the hydroponic tanks from their original positions perpendicular to the axial thrust line of the ship the southern hemisphere, it turned out that half of the plants had a sinistral corkscrew and the other half had a dextral. So I had to set the plants up in two different rooms, and run an artificial sun for It was full of minerals and manure and such, and I didn't want to introduce it into the ship's tanks." situation fairly well under control, but like you, I hadn't thought things through. The plastic membranes hadn't torn when we brought the mosquito. They had apparently been swimming in the water during their larval stage. Instead of making cocoons for themselves, they snipped "I couldn't figure whether to turn up the fans and dissipate the cloud—by spreading it all through the ship—or whether to try to block off the other plant room, and save it at least. So I ended up by not doing anything, which was the right thing to do. No more plants died because it's poisonous to humans too. marocca. The larvae provide an enzyme without which the plants die. "Of course. I immediately stopped slapping at the relatively few midges that had made their way into the head with me, and started to change the air in the ship to get rid of the poison. I knew it was too late given their larvae in moving the tanks and dipping the water up in buckets and all that had inhibited them in completing their cycle the "And the reason they had the same life cycle as the carolla was that fill itself full to bursting before it will reproduce. If I had the translation done correctly, they were supposed to dart gracefully inquisitive. They explored the whole ship, going into places I wouldn't have believed it to be possible for them to reach, including the inside of the main computer, which promptly shorted out. I finally figured "I got up with the sun the next morning. Hell, I had to, considering that it was I who turned the sun on! I found that the dingleburys immediately got busy opening small buds on the stems of the marocca plants. Apparently they were pollinating them. I felt sure that these buds weren't the marocca blossoms from which the fruit formed—I'd seen a lot of those while we were on Mypore II and they were much but I was busy. "Anyway, the action of the dingleburys triggered the violent growth phase of the marocca plants. Did you know that they plant marocca seedlings, back on Mypore II, at least you'll recall, a mature field, which was the only kind we ever saw, is one solid mass of green growth. "The book says that it takes just six hours for a marocca field to shift from the seedling stage to the mature stage. It didn't seem that long. You could watch it wouldn't do its job right. In effect, their growth would put out the one of the things they do is to defend the marocca against marauders. "And what's more, I found that I couldn't kill the damn things. Not if other to the point where they curled up and died, and I had to do it Made them forget all about me. "While they were having their orgy, I caught up on my reading. It was necessary for me to cut back the marocca vines. For one thing, I couldn't get up to the area of the bridge. For another, the main computer was completely clogged. I could use the auxiliary, on the back to normal as soon as possible. But before cutting, I had to translate the gouge. "It turns out that it's all right to cut marocca as soon as it stops growing. To keep the plants from dying, though, you have to mulch the cuttings and then feed them back to the plants, where the roots store growth. Of course, if you prefer you can wait for the vines to die back will poison the plants if they are fed back to them without having been "I was the special processor. That's what the instructions said—I translated very carefully—it required an 'organic processor'. "So I had to eat pounds of that horrible tasting stuff every day, and process it the hard way. didn't bother me any. I was far beyond the point where hay fever could had finished. "Well, go on," I urged him. "The marocca plants were still in good shape, weren't they?" Hannah nodded. "They were growing luxuriously." He nodded his head a He said, "They made me burn the entire crop right away, of course. They didn't get all of the carolla or dingleburys, though. Or spores." "Gloryanna III is the original home planet of marocca. They hated the stuff, of course, but they liked the profit. Then, when a plague almost crop. It wasn't as lucrative, but it was so much more pleasant that they outlawed marocca. Took them almost fifty years to stamp it out completely. Meanwhile, some clever native shipped a load of the stuff to Mypore II. He took his time, did it without any trouble and made his Delta Crucis as security to pay for the cost of stamping out marocca all over again—those spores sprout fast—and for a time I was worried. "Of course, when I showed them our contract—that you alone were

<question>:
If the marocca plants happened to die during transport, what would be one logical explanation for why they died based on the conditions they needed to survive in the article?

<options>:
A The temperature of the environment did not vary enough and was too stagnant for the plants.
B The carollas decided to start eating the dingleburys instead of vice versa.
C An error on the spaceship caused the artificial days and nights to not be equal length.
D The spaceship was not correctly simulating all the seasons that the marocca needed to be subjected to in order to grow.

C
