Air pollution, together with littering, are causing many problems in our large, industrial world.
Đáp án D
“Air pollution” là danh từ không đếm được và là chủ ngữ số ít nên động từ theo sau nó phải được chia ở số ít. Vậy nên, đáp án D - are → is.
Tạm dịch: Ô nhiễm không khí, cùng với việc xả rác bừa bãi, đang gây ra nhiều vấn đề trong thế giới công nghiệp hóa rộng lớn của chúng ta.
* Mở rộng: Các cụm “with, along with, as well as, together with, accompanied by, besides, in addition to...” thực chất ra là các giới từ. Vì vậy, các cụm này kết hợp với danh từ theo sau, ví dụ như trên đề bài là “together with littering”, tạo thành một cụm giới từ - có vai trò làm trạng ngữ trong câu, nên động từ trong câu sẽ không bị ảnh hưởng bởi các cụm này bởi động từ chỉ chia theo chủ ngữ chứ không chia theo trạng ngữ.Gói VIP thi online tại VietJack (chỉ 400k/1 năm học), luyện tập gần 1 triệu câu hỏi có đáp án chi tiết

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 from 43 to 50.
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 significantly 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 temperatures 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
