In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
One example: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Now, solve this: Article: "You know, these cups bring to mind a tea quote I heard." Mary's aunt said. She poured tea. There were four of them and there were four totally different cups on the table. They took their tea cups. "What quote?" Mary asked. "Well, maybe I should rather say it is a story," aunt said, "I heard that there was a wise teacher who took all his students for tea. They were surprised that all the cups on the table were different. Each of them took a cup and started drinking their tea, each looking at the cups of others. The teacher let them do that for a while and then said,' Do you notice your behavior? You are all looking at each other's tea cup and I can see some of you with the broken ones are even envious of the finer cups of others. Is this not so?' " The students agreed, amused by their own behavior. "You may have wondered why you all had different cups, but I put them here on purpose. You see they represent life itself. Life is like that tea and the cups are like the physical circumstances of your life. You all got the same thing in your cups -- tea. And yet you can not truly enjoy it in your envy of another's cup. It's just the same with life. You forget to enjoy your own life when you concentrate on envying the circumstances of someone else's life. So now, close your eyes, and taste your own tea. Really taste it. And tell me -- did it matter from which cup it came from?" Aunt finished telling her short tea story and they all sat in silence for a while, tasting their tea. A sleepy fly buzzed past, a bird sang in the tree. And it really did not matter one bit from which tea cup they drank.
Question: When the students found they had different tea cups, they _ .
Options: (A) were satisfied with their own cup (B) were angry about the broken cups they had been given (C) asked the teacher to get new cups for them (D) were curious about the difference between the cups
