<passage>:
on Mars By JACK SHARKEY Somebody had to get the human trip to Mars. He was always getting sandy, but handkerchiefs over nose and mouth solve this. We look like desperadoes, what Kroger and Pat, with the help of the aliens. Or maybe I should call them the Martians. Either way, it's better than what Jones calls them. fired, but the shots either bounced off their scales or stuck in their thick hides. Anyway, they took the rifles away and threw them into the stream, and picked us all up and but it didn't get dark. Kroger tells me that there are phosphorescent bacteria living in the mold on the walls. The air has a fresh-dug-grave make it a gift to Martian archeologists? a short and unscientific word and went to sleep. There's a Martian guarding the entrance to our cave. I don't know Mars. And I kept a diary. This is what they intend to do with us. Feed us, I hope. So far, they've just we're aimed toward where Mars on all four sides by running water, maybe twenty feet across, and we're on it. Martians keep coming to the far edge of the water and looking at us and whistling at each other. A little Martian came near the edge of the water and a larger Martian whistled like crazy and dragged it away. "Water must be dangerous to else. Right now I could eat a dinner raw, in a centrifuge, and keep it down. A Martian threw a stone at Jones today, and Jones threw one back at him and broke off a couple of scales. The Martian whistled furiously and went away. When the crowd thinned out, same as it did sleeping cycle here), Kroger talked Lloyd into swimming across the river and getting the red scales. (they call it the bulkhead, for some reason or other) table, scratching away with a ballpoint cold water, with the scales gripped in his fist. Or what was left of the scales. They had melted down in the water and left his hand all sticky. studied them in the uncertain light, then tasted them and grinned. The Martians are made of sugar. Later, same day . Kroger said that the Martian metabolism must be like Terran (Earth-type) metabolism, only with no pancreas to make insulin. They store their outside of their bodies, in the form of scales. He's watched them more closely and seen that they have long rubbery tubes for tongues, and that they now and then suck up water from us, being careful not to get their lips (all sugar, of course) wet. He guesses that their "blood" must be almost pure water, and that it washes away (from the inside, of course) the sugar they need for their bodies isolated carbon from water) to make sugar, a common carbohydrate. Like plants, on Earth, he said. Except, instead of using special cells on leaves to form carbohydrates with the help of sunpower, as Earth plants do in photosynthesis scales like prisms, to isolate the spectra (another Kroger word) necessary to form the sugar. in that medium, they lose all energy and die. Two: even partial sprinkling alters the shape of the scales, and they are unable to use sunpower to form more sugar, and still die, if a bit slower." of theirs. They must be for biting something more substantial than moss, Kroger." But there's some kind of a "drag." I told him I hoped it didn't mean The Martians have coal mines. we'd land on Mars upside down. He Jones got the rifles out of the stream (the Martians had probably thought they were beyond recovery on Mars?" and tell what we've learned about Mars (we know there are Martians, and they're made of sugar). "Why," I said, "can't we just tell Mary, Mary, quite contrary, How does your garden grow? With Martian rime, Venusian slime, And a radioactive hoe. I showed it to Kroger. He says Mars, so escape velocity didn't have to be so fast, hence a smoother (relatively) trip on our shock-absorbing Hell's bells . Kroger says there are two baby Martians loose on board ship. Pat told him he was nuts, but there are certain Earth for instructions. We can't. Here we are, somewhere in a void headed for Earth, with enough air and water left for maybe three days—if the Martians don't take any more. Kroger is thrilled that he is Mars has Martian reproductive processes. the whole screen filled. Looks like Death Valley. No When he told Pat, Pat put it to a vote whether or not to jettison and I'm very thirsty. Kroger says that at least—when the Martians get bigger—they'll have to show themselves. Pat says what do we do from Earth. So we just have that all turn into little Martians. Jones says he'll go down spitting. Pat says why not dismantle interior says it's the dust. The sand underfoot is kind of rose-colored, and not the carbon in the AFAR system. We'll have to try it, I guess. The Martians ate the bread. Jones came forward to tell us the got back they were gone. However, he did find a few of the red crystals on the galley deck (floor). They're good-sized crystals, too. Which means so are the Martians. Kroger says the Martians must be intelligent, otherwise they couldn't have guessed at the carbohydrates a lifelong diet of anthracite. Pat by suggesting the crystals be pulverized and mixed with sulphuric acid. He says this'll produce the rocket. Meantime, we have to catch those Martians. June 29, 1961 Worse and worse . Lloyd caught one of the Martians in the firing chamber. We had to flood the chamber with acid to subdue the creature, which carbonized nicely. So now we have plenty of air and water again, but besides having another Martian still on the loose, we now don't have enough acid left in the fuel tanks Pat says at least our vector will carry us to Earth and we can die was red and scaly, and I think it had a tail. It was two heads taller than you." He shuddered. "Ran off Martian is still with us. He's where we can't get at him without blow-torches, but he can't get at the carbon made of carbohydrates, too. I'd rather not have known. my diary aboard, and towed the rocket to San Francisco. News of the "captured Martian" leaked out, and we all became nine-day wonders until the dismantling of the unless they get covered up, too. We're taking extra oxygen, shells, those big tracks nearby. We're taking the jeep to follow the aliens' tracks. There's some moss around would do. There are about a thousand of those crystal-scales on a Martian. So last week we found out, when those red-scaled things began clambering out of the sea on every coastal region on Earth. Kroger tried here, on reddish brown rocks that stick up through the sand, just on The point is, bullets won't stop these things, and wherever a crystal falls, a new Martian springs up in a few weeks. It looks like the five of us have abetted an invasion from Mars. Needless to say, we're no longer heroes. here is hard-packed and damp, and there are normal-size footprints mingled with the alien ones, sharp and clear. The aliens seem to have six or seven toes. It varies from print to print. And they're barefoot, too, or else they have the damnedest-looking shoes in creation. The constant shower of sand

<question>:
How do the Martians reproduce?

<options>:
A The Martians are made of sugar. Once the body dissolves in the water a new body forms, like a phoenix rising from the ashes.
B The Martians reproduce the same way humans do.
C The red scales the Martians leave behind are like eggs. New Martians hatch out of the scales.
D The Martians are covered in red scales. The scales are shed. The discarded scales grow into new aliens.

D
