Article: Children today would rather toy with new technologies. The role of children has changed as well as that of teens. The world has truly evolved throughout the years. Today,a typical day in the life of a five year old is entirely different from what it once was. A few decades ago children used to work. They did the kind of work parents do today. Today there are shows on which children are putting pounds of makeup on and have flashing things all over their bodies. This makes a child want to _ all of their imperfections. They think they have to look perfect all the time. Teens have changed as well. My grandma got married when she was thirteen. Girls who had an arranged marriage had no time to play because they were expected to cook, clean,take care of the kids, and do housework every single day. Today,we go to school every morning, maybe participate in some after-school activities, and possibly go to work for extra cash. Then we go home and do homework, and eat. After all of this we have to find the time to socialize by texting, talking on the phone, or logging on to social networking sites. We enjoy ourselves a lot. The generation before us complains about how they did not have the things we have now. They say we are not appreciative and do not value life or just do not care about our futures anymore. Let's make a change! The youth have the power to work on whatever they believe in and make a difference in the world. Take advantage of your resources. It is never too late to make a positive change in our world.

Article: A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says. Researchers studied the effects of tranexamic acid , or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journalLancet.Doctors found that patients who got TXA had a 15percent lower chance of dying from _ than those who didn't get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government. The drug is commonly used in wealthy countries during elective surgeries to stop bleeding , but isn't used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection and would be relatively easy to introduce, even in poor countries, experts said. Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots in the heart and lungs, strokes, or heart attacks. There was no evidence of that in theLancet study, though the authors said it was possible they might have missed some of these incidents. For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn't tested on children , experts said it would almost certainly work with them as well.
Question: What can we learn about TXA from the passage?
Options: (A) It can only be made in England (B) It was only used in operations before (C) It is a patented drug (D) It is mainly used in poor countries
