প্রশ্নে বলা হচ্ছে, 5000 টি স্ট্যাম্প দুই ভাই বোনের মধ্যে 5 : 3 অনুপাতে ভাগ করে নিল। এরপর ঐ ভাই তার প্রাপ্ত স্ট্যাম্পগুলি তার দুই বন্ধুর সাথে 3 : 1 : 1 অনুপাতে ভাগ করে নিল । তার প্রত্যেক বন্ধু কতটি করে স্ট্যাম্প পেয়েছিল?

Given, Brother : Sister = 5 : 3

Here, sum of their ratio = 5 + 3 = 8

∴ Brother received = 5000× 58= 3125

Again, sum of the ratio of brother and his two friends = 3 + 1 + 1 = 5

∴ Each friend received = 3125 × 15 625 stamps

Precis writing: Ericsson and his colleagues then compared amateur (অপেশাদার ক্রিড়াবিদ) pianists with professional pianists. The same pattern emerged. The amateurs never practiced more than about three hours a week over the course of their childhood, and by the age of twenty they had totaled two thousand hours of practice. The professionals, on the other hand, steadily increased their practice time every year, until by the age of twenty they, like the violinists (বেহালাবাদক), had reached ten thousand hours. The striking thing about Ericsson's study is that he and his colleagues couldn't find any “naturals” musicians who floated effortlessly to the top while practicing a fraction of the time their peers did Nor could they find any "grinds". people who worked harder than everyone else, yet just didn't have what it takes to break the top ranks. Their research suggests that once a musician has enough ability to get into a top music school, the thing that distinguishes (দু'টি জিনিসের মধ্যে পার্থক্য শোনা, দেখা, বোঝা) one performer from another is how hard he or she works. That's it. And what's more, the people a the very top don't work just harder or even much harder than everyone else. They work much, much harder.The idea that excellence at performing a complex task requires a critical minimum level of practice surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is the magic number for true expertise: ten thousand hours. The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world- class expert-in anything, writes the neurologist Daniel Levitin. In a study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, this number comes up again and again. Of course, this doesn't address why some people get more out of their practice sessions than others do. But no one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.Instruction: Write a summary of the above passage with an appropriate title in the stipulated space.

Translation: English to Bengali Economic affluence and prosperity are likely to reduce the scope and necessity of social protest which is a common phenomenon in many of the developing nations. Though the proposition is not always true and failed to pass the test of time in many countries and many societies, governments in one developing countries nowadays strongly uphold the concept. That's why they have concentrated their focuses, resources and efforts to economic growth to turn their countries affluent and prosperous. The growth-centric or growth-obsessed drive towards prosperity mostly sidelines the distributive aspects which is a major factor of different social protests. Theoretically, social protest is defined as a form of political expression that seeks to bring about a social or political change by influencing the knowledge, attitudes and behaviors of the public or the policies of an organization or institution. These protests generally take the form of overt public displays, demonstrations, civil disobedience and may also include covert activities like petitions, boycotts, lobbying, and even different online activities.

In Bangladesh, different kinds of social protests have been observed in last couple of years when economy registered an unrelenting growth Usually social protests mostly ended within a period of time and mostly never linger unless those are serious issues. Those who participate in the protests do not come for any revolutionary change overnight. They mostly want to draw the attention of the policymakers and authorities to rectify the defects within a reasonable time frame.

Patriotism is a quality that inspires a man to do everything just and fair for well-being and betterment of the country. It is the quality that impels a man to sacrifice his own interest, comfort pleasure and even his life. Patriotic zeal makes a man dutiful. He cannot sit idle. He is energetic and enthusiastic to work for the country. He obeys the laws, pays taxes and thinks for the betterment of the country. Patriotism is a quality that teaches a man fellow-feeling, fraternity, love and sympathy for the countrymen. A patriotic man gets pleasure in removing the suffering and sorrow of his fellowmen. He devotes his time and energy to develop the country, its culture and civilization, its economic and political systems. On the contrary, a man devoid of patriotic zeal engages all his time in achieving mean end. (Translation: English to Bangla)
