Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct answer to each of the questions.
A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison had to make more than 1,000 attempts to invent the incandescent light bulb before he finally succeeded. History is replete with numerous other examples of people trying, yet failing to make inventions before they eventually succeeded. Yet some inventions have come about not through hard work but simply by accident.
In most cases, when someone unintentionally invented something, the inventor was attempting to create something else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a new substance that could be used to refrigerate items. He mixed some chemicals together. Then, he put them into a pressurized container and cooled the mixture. By the time his experiment was complete, he had a new invention. It was not a new substance that could be used for refrigeration though. Instead, he had invented Teflon, which is today most commonly used to make nonstick pots and pans. Similarly, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia. He was attempting to create a tonic that people could use whenever they had headaches. While he was not successful in that endeavor, he managed to invent Coca – Cola, the world – famous carbonated soft drink.
Scientists have also made crucial discoveries by accident when they were conducting experiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. He discovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemed to be avoiding the mold. When he investigated further, he determined some of the many useful properties of penicillin, which has saved millions of lives over the past few decades. Likewise, in 1946, scientist Percy Spencer was conducting an experiment with microwaves. He had a candy bar in his pocket, and he noticed that it suddenly melted. He investigated and learned the reason why that had happened. Soon afterward, he built a device that could utilize microwaves to heat food. the microwave oven.
What does the author say about Teflon?
A. It is used for kitchenware nowadays.
B. It was created many years before Coca–Cola.
C. The man who made it was a pharmacist.
D. People first used it as a refrigeration device.

DỊCH BÀI
Một số lượng lớn các phát minh đòi hỏi nhiều năm nghiên cứu và phát triển gian khổ trước khi chúng được hoàn thiện. Chẳng hạn, Thomas Edison đã phải thực hiện hơn 1.000 nỗ lực để phát minh ra bóng đèn sợi đốt trước khi cuối cùng ông thành công. Lịch sử là đầy đủ với nhiều ví dụ khác về những người đang cố gắng, nhưng không thể tạo ra các phát minh trước khi cuối cùng họ đã thành công. Tuy nhiên, một số phát minh đã xuất hiện không phải thông qua công việc khó khăn mà chỉ đơn giản là tình cờ.
Trong hầu hết các trường hợp, khi ai đó vô tình phát minh ra thứ gì đó, nhà phát minh đã cố gắng tạo ra thứ khác. Ví dụ, vào những năm 1930, nhà hóa học Roy Plunkett đã cố gắng tạo ra một chất mới có thể được sử dụng để làm lạnh các mặt hàng. Anh trộn một số hóa chất với nhau. Sau đó, anh cho chúng vào một thùng chứa có áp suất và làm nguội hỗn hợp. Đến khi thí nghiệm của anh hoàn thành, anh có một phát minh mới. Nó không phải là một chất mới có thể được sử dụng để làm lạnh. Thay vào đó, ông đã phát minh ra Teflon, ngày nay được sử dụng phổ biến nhất để làm nồi và chảo không dính. Tương tự, nhiều thập kỷ trước đó, John Pemberton là một dược sĩ ở Atlanta, Georgia. Ông đã cố gắng tạo ra một loại thuốc bổ mà mọi người có thể sử dụng bất cứ khi nào họ bị đau đầu. Trong khi anh ta không thành công trong nỗ lực đó, anh ta đã phát minh ra Coca - Cola, nước ngọt có ga nổi tiếng thế giới.
Các nhà khoa học cũng đã có những khám phá quan trọng một cách tình cờ khi họ đang tiến hành thí nghiệm. Năm 1928, Alexander Fleming đã phát hiện ra penicillin, một loại kháng sinh, theo cách này. Ông phát hiện ra một số nấm mốc phát triển trong một món ăn có một số vi khuẩn. Ông nhận thấy rằng vi khuẩn dường như đang tránh nấm mốc. Khi điều tra sâu hơn, ông đã xác định được một số trong nhiều đặc tính hữu ích của penicillin, thứ đã cứu sống hàng triệu người trong vài thập kỷ qua. Tương tự như vậy, vào năm 1946, nhà khoa học Percy Spencer đang tiến hành một thí nghiệm với vi sóng. Anh ta có một thanh kẹo trong túi, và anh ta nhận thấy rằng nó đột nhiên tan chảy. Ông đã điều tra và tìm hiểu lý do tại sao điều đó đã xảy ra. Ngay sau đó, anh đã chế tạo một thiết bị có thể sử dụng lò vi sóng để hâm nóng thức ăn. lò vi sóng.
