2 জন পুরুষ ও 5 জন মহিলার একটি দল 3 দিনে একটি কাজের 1/4 অংশ করল। 3 দিন পরে, আর একজন পুরুষ ঐ টিমে যোগ করলেন এবং তারা একত্রে 2 দিনে আরো 1/4 অংশ কাজ করল। কত জন পুরুষ 4 দিনে কাজটি করতে পারবে?

2 men and 5 women require 3 days to complete 14 job

∴ They complete 14 ×3 = 112 job in 1 day.

3 men + 5 women require 2 days to complete 14 job;

∴ They complete 14 ×2= 18 in 1 days.

3 men+5 women   = 18 2 men +5 women  = 112                 (Subtracting) 1 man = 18 - 112 = 3-224 =124

 

124 job is done in 1 day by 1 men

∴ 1 job is done in 1 day by 24 men

∴ 1 job is done in 4 day by 244 = 6 men

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.

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)

Prepare a summary of the following text: All through history there have been wars, yet mankind has survived, developed, and became civilized in spite of them. But unfortunately, as part of his development, man has learned to tap the hidden forces of our planet and use them for his purposes. Now, if his purposes are those of destruction, each fresh advance in his mastery of nature only increases the danger from war, as men learn to destroy one another in ever greater numbers, from ever greater distances, and in ever more varied and ingenious ways. Man has now discovered how to release the forces locked up in the atom. In consequence, the leading nations of the world are now making atom bombs which would almost certainly be widely used. Nobody knows what the effect of dropping such bombs on a large scale would be, but it is quite possible that the total destruction of the world and its civilization might ensue. As somebody has jokingly remarked, in the next war, men will fight with atom bombs and in the war after that with bows and arrows.
