Article: Six-month-old babies are strictly limited in what they can remember about the objects they see in the world. If you hide several objects from babies, they will only remember one of those objects. But a new study, which was published in an issue of Psychological Science, a journal of the Association for Psychological Science, finds that when babies "forget" about an object, not all is lost. Researchers used to think that babies less than two years old did not understand that an object continues to exist when it is not in the baby's view. But in mid-1980s, new ways of doing experiments with babies found that they do, in fact, know that objects don't disappear when they do not look at them -- a concept known as object permanence. But it was still unknown what babies needed to remember about objects in order to remember their existence. Now Melissa Kibbe, of John Hopkins University, and Alan Leslie, of Rutgers University, are working to figure out exactly what it is that babies remember about objects. For the new study, they showed six-month-old babies two objects, a disk and a triangle. Then they hid the objects behind small screens, first one shape, then the other. Earlier research has shown that young babies can remember what was hidden most recently, but have more trouble remembering the first object that was hidden. Once the shapes were hidden, they lifted the screen in front of the first object. Sometimes they showed babies the shape that was hidden there originally , but sometimes it was the other shape, and sometimes the object had _ completely. Psychologists measure how long babies look at something to see how surprised they are. In Kibbe and Leslie's study, babies weren't particularly surprised to see that screen had changed, for example, from a triangle to a disk. But if the object was gone altogether, the babies looked significantly longer, indicating surprise at an unexpected outcome: "This shows that even though babies don't remember the shape of the object, they know that it should continue to exist," Kibbe says. "They remember the object without remembering the features that identify that object." This helps explain how the young brain processes information about objects, Leslie say. He thinks the brain has a structure that acts like a kind of pointer, a mental finger that points at an object.
Question: Before the study, which of the following was unclear?
Options: (A) Whether babies know objects are gone. (B) What made babies remember objects' existence. (C) Whether babies can remember what was hidden first. (D) Why babies were interested in what was hidden.
Asnwer: D

Ex Output:
No

Article: I still remember the days when I was a youthful student in an engineering school. I lived a casual life, without caring about the future. I smoked, drank with friends and made girl friends. Little did I realize that casualness would certainly lead to loss. Two years had passed and I was staring down a report card that highlighted FAIL in more than half the subjects. I didn't care, at least not till my dad found out about it. You see, I studied in India and unlike the United States where the students are expected to finance their own education, my dad financed me. Then came the day when my dad found out my habit of smoking. He lost his temper but he just told me, "Son, your allowance is cut in half from this moment on". It hit me like a roundhouse kick from Bruce Lee. I was jolted out of my bones! I couldn't comprehend how to pay off the debts that I had accumulated in college. I owed everybody money: the grocery store, the bars, the restaurants, my friends, etc. I was living a life filled with credit. When I went back to college, I knew that if I don't change the way I live my life I won't be able to pay everybody off. So I decided to make some changes, drastic changes. I quit smoking, cut off from my friends who led me down the wrong road, starting hanging out in libraries and reading my engineering books. One year later, I went from a miserable failure to a magna cum laude . . This incident made me know that anything is possible if you take action and do something about it, however small or large. Even today it still motivates me when I feel that I'm about to lose or give up. It reminds me that I can do it!

Article: The next time you get caught jumping on your bed you can tell your parents with a straight face that you are not playing, simply getting ready got a promising career in "Mattress Jumping". Believe it or not, there are some people who actually get paid to do that! According to Reuben Reynoso, a professional mattress tester at San Francisco's McRoskey Mattress Factory that still makes every mattress by hand, it is real work and needs some training. For a start, it's not all about jumping to new heights or doing tricks like professional athletes, but rather about feeling each area of the mattress carefully to detect the filling. In order to do it right, every bit of the mattress has to be tested slowly and deliberately. Over the years, Reynoso has figured out the perfect routine. He begins by placing a protective mat over the mattress so that it doesn't get dirty or absorb the smell from his feet. Then begins the fun---he steps to the middle of an edge and then takes five steps back and five steps forward. In this way, he slowly but surely, covers the entire surface. The key according to him is to find the perfect number of jumps---Too many and he will end up destroying the mattress completely. Too few? And it will not fit into the giant machine for that final sewing! Who knew a job that sounds so simple could have so many skills! While Reuben will not reveal how he got into this profession, he will admit that it is more fun than being a carpenter, roofer, construction worker and railroad engineer---all jobs he has tried previous to finding his true profession!
