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.

The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.

Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic rays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn’t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.

Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significant greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.

However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperature were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.

Most of the helium in the universe was formed ______

A. during the first minute of the universe's existence

B. in a very short time

C. in interstellar space

D. before most of the hydrogen

Hầu hết helium trong vũ trụ được hình thành ______

A. trong phút đầu tiên của sự tồn tại của vũ trụ B. trong một thời gian rất ngắn

C. trong không gian giữa các vì sao D. trước phần lớn hydro

Thông tin: However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperature were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist.

Tạm dịch: Tuy nhiên, khi vũ trụ hình thành chưa đầy một phút, Heli đã không thể tồn tại. Các tính toán cho thấy rằng trước khi nhiệt độ thời gian này là quá cao và các hạt của vật chất đã được di chuyển xung quanh nhiều quá nhanh. Chỉ sau mốc một phút Heli mới thể tồn tại.

Chọn B

Dịch bài đọc:

Các yếu tố ngoài Hydro và Heli tồn tại với số lượng nhỏ đến nỗi chính xác khi nói rằng theo trọng lượng, vũ trụ có phần hơn 25 phần trăm heli tính và phần nào ít hơn 75 phần trăm Hydro.

Các nhà thiên văn đã đo sự dư thừa của Heli khắp thiên hà của chúng ta và các thiên hà khác. Heli đã được tìm thấy trong những ngôi sao tồn tại đã lâu, ở những ngôi sao tương đối mới, trong khí giữa các vì sao, và trong các đối tượng ở xa gọi là chuẩn tinh. Hạt nhân helium cũng đã được tìm thấy là thành phần của các tia vũ trụ chiếu xuống Trái đất (tia vũ trụ không phải là thực sự là một dạng bức xạ, chúng gồm các hạt của nhiều loại khác nhau di chuyển nhanh chóng). Nó dường như không làm khác biệt đi nhiều nơi Heli được tìm thấy. Sự phong phú tương đối của nó dường như không bao giờ thay đổi nhiều. Ở một số nơi, có thể có nhiều hơn một chút; ở những nơi khác, một chút ít, nhưng tỷ lệ Heli trên các hạt nhân Hydro luôn luôn vẫn như nhau.

Helium được tạo ra trong các ngôi sao. Trong thực tế, phản ứng hạt nhân mà chuyển đổi Hydro thành Heli đảm nhiệm hầu hết năng lượng mà các ngôi sao tạo ra. Tuy nhiên, lượng Heli có thể đã được sản xuất theo cách này có thể được tính toán, và hóa ra là không có nhiều hơn một vài phần trăm. Vũ trụ đã không tồn tại đủ lâu để con số này là lớn hơn đáng kể. Do đó, nếu vũ trụ là có phần hơn 25 % Heli bây giờ, thì nó phải có được khoảng 25% Heli tại một thời điểm gần lúc nó hình thành.

Tuy nhiên, khi vũ trụ hình thành chưa đầy một phút, Heli đã không thể tồn tại. Các tính toán cho thấy rằng trước khi nhiệt độ thời gian này là quá cao và các hạt của vật chất đã được di chuyển xung quanh nhiều quá nhanh. Chỉ sau mốc một phút Heli mới thể tồn tại. Đến thời điểm này, vũ trụ đã quá nguội đến nỗi Nơtron và Proton có thể kết hợp vào nhau. Nhưng phản ứng hạt nhân dẫn đến sự hình thành của Heli đã hoàn thiện trong một thời gian tương đối ngắn. Sau khi vũ trụ được hình thành vài phút, việc tạo ra Heli đã không còn hiệu quả.
