Read the following passage and answer the questions
Thomas Alva Edison was born in 1847 in Ohio, America. As a little boy, he was very inquisitive. He always wanted to know how things were done. Very early in life he showed that he was full of curiosity, a quality which is so important to inventors. In 1869 he went to New York where he worked for some time as a telephone operator. But soon he became interested in inventions. In a very short time they were his chief business. In order to carry on this business, which became his life's work, he built a laboratory at Menlo Park, where he had gone to live. His first great invention was a system of telegraphy. Soon afterwards he invented the phonograph, the first form of the instrument that we now know as the gramophone' or record player. The word 'phonograph means something that can write or record sound. Other scientists before Edison had thought of instruments which would do this, but Edison was the first to make an instrument which actually worked. He also invented the incandescent' lamp, a lamp in which the light is caused by a heated wire called a 'filament'. The wire is heated by an 'electric current'. People can now use 'electricity' to illuminate their homes. By the time Edison died in 1931 he had about a thousand inventions to his credit.

বাংলা অনুবাদ:
থমাস আলভা এডিসন ১৮৪৭ সালে ওহাইও, আমেরিকায় জন্মগ্রহণ করেন। ছোটবেলা থেকেই তিনি অত্যন্ত কৌতূহলী ছিলেন। তিনি সব সময় জানতে চাইতেন কিভাবে জিনিসপত্র কাজ করে। খুব অল্প বয়সেই তিনি দেখিয়েছিলেন যে তিনি অনুসন্ধিৎসু, যা উদ্ভাবকদের জন্য একটি গুরুত্বপূর্ণ গুণ।
১৮৬৯ সালে তিনি নিউ ইয়র্কে যান এবং কিছু সময়ের জন্য টেলিফোন অপারেটর হিসেবে কাজ করেন। কিন্তু খুব দ্রুত তিনি আবিষ্কারের প্রতি আগ্রহী হয়ে ওঠেন। অল্প সময়ের মধ্যেই এটি তার প্রধান কাজ হয়ে ওঠে। এই কাজ চালিয়ে যাওয়ার জন্য, তিনি মেনলো পার্কে একটি গবেষণাগার তৈরি করেন, যেখানে তিনি বসবাস করতেন।
তার প্রথম গুরুত্বপূর্ণ আবিষ্কার ছিল একটি টেলিগ্রাফি ব্যবস্থা। কিছুদিন পর, তিনি ফোনোগ্রাফ আবিষ্কার করেন, যা বর্তমানে গ্রামোফোন বা রেকর্ড প্লেয়ার নামে পরিচিত। ‘ফোনোগ্রাফ’ শব্দের অর্থ এমন কিছু যা শব্দ লিখতে বা রেকর্ড করতে পারে।
এডিসন ছাড়াও অন্য বিজ্ঞানীরা এমন যন্ত্রের কথা ভেবেছিলেন, কিন্তু তিনিই প্রথম ব্যক্তি যিনি সত্যিকারের কার্যকর একটি যন্ত্র তৈরি করেছিলেন। এছাড়া, তিনি ইনক্যান্ডেসেন্ট বাতি আবিষ্কার করেন, যেখানে আলো একটি উত্তপ্ত তার বা ‘ফিলামেন্ট’-এর মাধ্যমে তৈরি হয়। এই তারটি বৈদ্যুতিক প্রবাহ দ্বারা উত্তপ্ত হয়।
এই আবিষ্কারের ফলে মানুষ তাদের বাড়ি আলোকিত করতে বিদ্যুৎ ব্যবহার করতে পারে। ১৯৩১ সালে মৃত্যুর পূর্বে, এডিসনের নামে প্রায় এক হাজার উদ্ভাবন ছিল।
