Đáp án A
Dịch đề bài:
Ở dòng 17, từ “most” chỉ...
A. Phần lớn các nhà sinh vật biển
B. Một vài con cá heo mũi chai
C. Rất nhiều cá heo mũi chai
D. Thiểu số các nhà sinh vật học biển
* Hướng dẫn làm bài:
Đối với loại câu hỏi này, đọc ngược lại 1-2 câu trước nó để tìm từ mà nó đang thay thế. Trích thông tin trong bài: “These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication.”
Tạm dịch: Những nghiên cứu này đã bị chỉ trích vì một số nhà sinh vật biển tin rằng cá heo sống trong bể cá hoặc trung tâm nghiên cứu không thể được coi là "bình thường". Mặc dù vậy, hầu hết đều tin rằng nghiên cứu hành vi giao tiếp của cá heo trong điều kiện nuôi nhốt là hữu ích để bắt đầu hiểu được sự phức tạp trong sự giao tiếp cá heo.
Như vậy, “most” ở đây chỉ hầu hết các nhà sinh vật biển. → đáp án A phù hợp.

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 36 to 42.
There are many theories of aging, but virtually all fall into the category of being hypotheses with a minimum of supporting evidence. One viewpoint is that aging occurs as the body's organ systems become less efficient. Thus failures in the immune system, hormonal system, and nervous system could all produce characteristics that we associate with aging. Following a different vein, many current researchers are looking for evidence at the cellular and sub cellular level.
It has been shown that cells such as human fibroblasts (generalized tissue cells) grown in culture divide only a limited number of times and then die. (Only cancer cells seem immortal in this respect). Fibroblast cells from an embryo divide more times than those taken from an adult. Thus some researchers believe that aging occurs at the cellular level and is part of the cell's genetic makeup. Any event that disturbs the cell's genetic machinery such as mutation, damaging chemicals in the cell's environment, or loss of genetic material, could cause cells to lose their ability to divide and thus bring on aging. Other theories of aging look at different processes. Chronological aging refers to the passage of time since birth and is usually measured in years. While chronological age can be useful in estimating the average status of a large group of people, it is a poor indicator of an individual person's status because there is a tremendous amount of variation from one individual to the next in regard to the rate at which biological age changes occur. For example, on the average, aging results in people losing much of their ability to perform strenuous activities, yet some elderly individuals are excellent marathon runners.
Another type of aging is cosmetic aging, which consists of changes in outward appearance with advancing age. This includes changes in the body and changes in other aspects of a person's appearance, such as the style of hair and clothing, the type of eyeglasses, and the use of a hearing aid. Like chronological aging, it is frequently used to estimate the degree to which other types of aging have occurred. However, it is an inaccurate indicator for either purpose because of variation among individuals and because a person's appearance is affected by many factors that are not part of aging, including illness, poor nutrition, and exposure to sunlight
