Input: Consider Input: Article: As the school year comes to an end, many senior students of school across the nation will not just be starting another summer of holidays to provide a break during semesters. Leaving their _ , many of them are to take their first step into the world of adulthood, attending fast-paced, crowded universities, taking up part-time or full-time employment. Many may even move from family homes in their pursuit of educational fulfillment or the "perfect" job opportunity. One ceremony that has become part of coming of age has been the senior prom . The senior prom is an opportunity for youth to celebrate the entrance into the world of adulthood with color and formality. However, there is far more behind the social event than ever noticed. What is formal? Formal means to present one's self to others in a way which is "with form", with shape, polite, inoffensive and organized. We see the example of a formal letter; it uses proper grammar and sentence structure in order to be respectful, while at the same time serving a purpose or getting an important message across. In our society, what is formal? Very little. On average, clothing, language, behavior --- all is very informal. Individuals who are formal (polite, inoffensive, organized) in their daily dealings with people are often looked upon as boring. Yet in certain situations, individuals play with the concept of formality not truly to achieve respectfulness and order but because it becomes fashionable to do so. While a prom may seem, on the surface, like a fun opportunity to behave formally, it is actually a flowery version of Halloween. On the occasion of the spring prom, we see flowering youth taking on the formalities of "adult". Fine dress, careful makeup, luxury cars all become part of being an adult. But being "adult" isn't that way. In our society we have a wrong idea of what adulthood actually is. It has always been my understanding that adulthood and maturity are not based upon one's ability to hold a cigarette in a certain way or tie a bow tie. Adulthood comes with understanding of one's place in the universe; it comes with the knowledge of how to interact with our fellow human beings; it comes with the ability to take responsibility for one's own actions --- whether good or bad.
Question: The writer holds the opinion that being an adult means one can _ .
Options: (A) put on heavy makeup (B) better get on with others (C) learn to smoke cigarettes (D) buy a luxury car or dress

Output: B

Input: Consider Input: Article: Compared to high heels , they don't look dangerous, but flip-flop wearers should think twice before slipping on a pair. The National Health Service spends PS40 million a year treating injuries caused by wearing the casual footwear. More than 200,000 people end up in hospital every year after suffering falls or developing long-term problems. Once worn only at the beach, flip-flops have become the regular summer footwear of choice for women, with two in five women owning at least one pair. But experts are warning the public of the dangers of wearing flip-flops, such as the risk of joint pains. They say flip-flops force people to change the way they walk so that when taking a walk with long steps they put pressure on the outside of their foot, rather than their heel, causing long-term damage. And there is also the risk of serious injury. Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground. Many also suffer aching toes as they constantly wear them. Mike, a spokesman, warned wearers of the damage done by flip-flops. He said, "They land on the outside and then roll the foot inwards putting all the pressure on the big toe." This constant rolling puts pressure on the ankle joint, causing it to weaken. The lack of support of the flip-flop also causes pain on the inside of the foot and lower leg. And if you're not used to wearing them, they can cause blisters , he added. Doctors say flip-flops cause far more damage as they are worn for longer periods of time. Emma Supple, consultant podiatrist , said, "Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that wearing on hard flat surfaces can cause considerable foot and leg problems." She encouraged women to wear suitable shoes to help recover from summertime injuries.

Options: (A) The benefits of wearing high heels. (B) The dangers caused by wearing flip-flops. (C) The advantages and disadvantages of wearing flip-flops. (D) Some advice on how to avoid injuries caused by wearing high heels.

Input: Consider Input: Article: As hand-held devices such as smartphones are becoming more common, users are reporting some new physical problems. Florida chiropractor Dean Fishman began noticing an increased number of patients talking about neck and shoulder pain. He discovered these symptoms were due to the overuse of hand-held devices, particularly the action of bending the neck, and then _ the term "Text Neck." As if the painful symptoms weren't bad enough, Fishman warns that an untreated case of Text Neck could lead to permanent spinal damage. Other doctors have warned about "iPad Hand," a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain. In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic principles: Avoid awkward positioning. Don't strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren't leaning over for a long period of time. Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes. When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle. Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you'll be resting both hands on the keyboard. And since you won't be holding the tablet, you'll be less likely to experience hand or arm pain.
