Example Input: Article: When school was out, I hurried to find my sister and get out of the schoolyard before seeing anybody in my class. But Barbara and her friends had beaten us to the playground entrance and they seemed to be waiting for us. Barbara said, "So now you' re in the A class. " She sounded impressed. "What' s the A class? "I asked. Everybody made superior yet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, Dopey? Didn' t you know you were in the C class before, way in the back of the room? " Of course I hadn' t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, and the idea of subdivisions within a grade had never occurred to me. The subdividing for the first marking period had been done before I came to the school, and I had never, in the six weeks I' d been there, talked to anyone long enough to find out about the A, B, and C classes. I still could not understand why that had made such a difference to Barbara and her friends. I didn' t yet know that it was shameful and dirty to be a transient laborer and ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house. I didn' t know that we were gypsies, really (how that thought would have excited me then! ), and that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn' t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here and there like mists or winds, I didn' t know that I was the only child who had camped on the Baumann' s land ever to get out of the C class. I didn' t know that school administrators and civic leaders held conferences to talk about the problem of transient laborers. I only knew that for two happy days I walked to school with Barbara and her friends, played hopscotch and jumped rope with them at class intervals, and was even invited into the house for some ginger ale--a strange drink I had never tasted before.

Example Input: Article: ,. Three-year-old Teddy Lasry was sleeping in his cowboy outfit yesterday at his family's Fifth Ave.apartment when he shot up in bed screaming.A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger. "The babysitter (a person taking care of children while their parents are away for a short time) was frightened to death," said Teddy's father, David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building's doorman.The doorman and two cable TV workers helped take the snake off the boy's arm and put it in a garbage bag.Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous.It wasn't.Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy's bed? A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys.The apologetic owner said his son's pet snake likely traveled up the water pipes and into his neighbor's apartment."It's a very gentle, very harmless snake," he said."It's handled by our family all the time." David Lasry believed the pet was simply hungry after two weeks of wandering.Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital. "I told Teddy he's a pretty snake, a nice pet snake who got out of his cage," Evelyn said."But he asked, 'Why did he bite my finger, Mamma?' And I said, 'Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.'"

Example Input: Article: The advantages of using flashcards to build up a vocabulary are well known. You can buy sets of cards, or make your own, and carry them with you wherever you go. There's no question this is useful and because you can use them in short bursts, it's not too much for you. It can be fun. I don't recommend drilling for hours at a time with flashcards. If you want to use flashcard software, things get even better. There are many packages out there for maintaining and drilling flashcards. I recommend VTrain though there are many others. One stands out, however: SuperMemo. Similar to Pimsleur, SuperMemo is engineered according to a carefully researched methodology in order to test you on a card the very minimum number of times you need to see it for it to stick. When you look at a card, you give some feedback to the software on whether you got it right and how easy you found it. It uses this information, and that of your previous attempts, to decide when you will be shown the card next. It's smart and it really works. If you're like me, the news is even better! I have a version of SuperMemo that runs on my PalmOS phone. Wherever I am, if I have my phone handy, I have thousands of flashcards with me too. Honestly, it would be worth purchasing a cheap Palm device only for this. You can pick one up for $20 or even less on eBay or elsewhere. Consider it, at least.
Question: With SuperMemo, whether the next card will be shown depends on _ .
Options: (A) the time you look at the card (B) the information in the computer (C) the feedback one gives to the software (D) the times one attempts to do with a card
Example Output:
C
